In this study role of peroxidase, lipids and phenolics in deterioration of quality of pearl millet in control and stored flour of high (HHB 94) and low (ICMA 94222 x 78/71) rancid genotype was determined. Fat content, fat acidity, free fatty acids, total phenols, C-glycosylflavones content and peroxidase activity of HHB 94 were higher than that of ICMA 94222 x 78/71. Storage of flour for 8 days of these two genotypes showed significant increase in fat acidity and free fatty acids. Storage had no effect on C-glycosylflavones content whereas peroxidase activity reduced significantly with storage time. Isozyme profile showed that pearl millet grains had 3 isozymes of peroxidase and banding pattern was similar in both HHB 94 and ICMA 94222 x 78/71. While banding intensity represented that ICMA 94222 x 78/711 had lesser peroxidase activity as compared to HHB 94. The result suggested that peroxidase activity, fat acidity and free fatty acid value were usually correlated.

Br.] is the staple food of majority of the poor and small land holders, as well as a source of feed and fodder for livestock in the rainfed regions of the country. Pearl millet excels all other cereals because it is a C4 plant with high photosynthetic efficiency and dry matter production capacity. It requires less inputs, matures in short duration and is considered as nutritious food, feed and fodder. It is usually grown under the most adverse agro-climatic conditions where other crops like sorghum and maize fail to produce economic yields. In India, pearl millet is the third most widely cultivated food crop after rice and wheat. It is grown on 7.128 million ha with an average productivity of 1132 kg/ha during 2015-16 (Directorate of Millet Development, 2017; Project Coordinator Review, 2017). The major pearl millet growing states are Rajasthan, Maharashtra, Gujarat, Uttar Pradesh and Haryana which account for more than 90% of pearl millet acreage in the country. Most of pearl millet in India is grown in rainy (kharif) season (June-September). It is also cultivated during the summer season (February-May) in parts of Gujarat, Rajasthan and Uttar Pradesh; and during the post-rainy (rabi) season (November-February) at a small scale in Maharashtra and Gujarat. The pearl millet grain is small but has a proportionally larger germ than all other cereal grains, except maize (Taylor 2004). The pearl millet grain comprises about 8% pericarp, 17% germ (which is proportionally large) and 75% endosperm (Serna-Saldivar & Rooney 1995). A thin waxy cutin layer covers the surface of the pericarp. Beneath the pericarp, is a thin layer of seed coat, and then a single aleurone layer (one-cell thick). Bran is hard outer layer of cereals which consists of combined aleurone, pericarp and part of germ. Generally the pericarp is thin, single layered with compact

The experiment consisted of 16 treatment combinations with two irrigation sources [canal and treated sewage water], two levels of farm yard manure [2.5 and 5 t ha −1 ] that assisted in main plots and four fertility levels [control, 50, 75 and 100% recommended dose of fertilizer (RDF, 156.25 kg N and 62.5 kg P 2 O 5 ha −1)] that assisted in subplots in split-plot design using three replications. The results revealed that the irrigation sources did not influence significantly growth parameters, protein percent, fat acidity, canopy temperature and grain yield. However, canal and treated sewage water differ significantly in respect of photosynthesis and chlorophyll content. Further, data showed that different fertility levels differed significantly (P ≤ 0.05). Higher leaf water potential, canopy temperature, photosynthesis and chlorophyll content were recorded with the application of 100% RDF over control, 50 and 75% RDF. The concentration of heavy metals (Pb, Cd, Ni and Co) decreased with increasing levels of FYM application from 2.5 to 5 tha −1 in plant, while in soils these were increased with increasing levels of FYM application. The interaction effect showed significant effect on pooled grain yield of pearl millet. Application of 100% RDF along with FYM @ 5.0 t/ha produced higher yield over 75% RDF + FYM @ 5.0 tha −1 and 50% RDF + FYM @ 5.0 tha −1 irrespective of irrigation sources. This clearly showed that higher application of FYM reduces the heavy metal accumulation in pearl millet irrigated with treated sewage water.

Path coefficient analysis based on genotypic correlation showed high positive and direct effects on grain yield per plant by ear girth and days to 50 per cent flowering. The high association of ear girth and effective tillers per plant with grain yield per plant; their large direct effects suggested maximum emphasis in selection for improvement of grain yield in pearl millet.

Crude protein content of various varieties ranged from 7.2 to 9.1 per cent. Total soluble proteins when separated by SDS-PAGE resolved into 11-17 bands and 22-29 bands in seeds and seedlings of various varieties, respectively. Protein pattern of seeds of various varieties were unique and could clearly distinguish all the varieties indicating that SDS-PAGE of seed proteins may be used as a reliable parameter for rice varietal/cultivar identification.

Br.]- mustard [Brassica juncea (L.) Czernj. and Coss.] cropping sequence. The study consisted of 12 treatment combinations of farmyard manure and inorganic fertilizers with micronutrients were laid out in Factorial Randomized Block Design with three replications. The mean data revealed that use of balanced fertilizers (Potash, gypsum, ZnSO 4 and FeSO 4 ) along with application of 5.0 tonnes FYM/ha in pearl millet-mustard crop sequence produced 7.5 per cent higher pearl millet grain yield (3.59 tonnes/ha) and 8.2 per cent more mustard seed yield (1.96 tonnes/ha) than no FYM application (3.34 tonnes/ha by pearl millet and 1.81 tonnes/ha by mustard).

Bran yield of analyzed hybrids/ composites varied from 9.2 to 13.8 %. In decorticated grains (endosperm fraction) phytate content varied from 5.0 mg/g (HC 20) to 6.54 mg/g (HHB 67 improved) with an average value of 5.92 mg/g while in bran fraction it varied from 3.96 mg/g to 4.90 mg/g with an average value of 4.42 mg/g. On an average 5.34 % increment in phytate content was observed on decortications which varied from 3.5 to 9.2 %. A positive correlation was observed between bran content and increase in phytate content in decorticated grains. It is concluded that phytate deposition occurs throughout the endosperm and bran fractions but deposition in endosperm fraction is significantly denser than that in bran fraction. Therefore, decortications migh...

At the same time, the seed’s sink strength plays an important role in dry matter accumulation. To investigate the relative contribution of pearl millet flag leaves to protein, micronutrient (Fe and Zn) and phytate accumulation, a field experiment was conducted to evaluate the effect of flag leaf removal on grain test weight (1000 grain weight), protein, micronutrients (Fe and Zn) and Phytate deposition in developing grains of two pearl millet cultivars viz. HC 20 and WHC 901-445. Flag leaf was removed on anthesis. Major effect of flag leaf removal was observed on test weight and protein content. A reduction of 10-12% in test weight and 4-6% in protein content was recorded in flag leaf removed plants than that of control plants. No significant red...

Across the groups, pearl millet genotypes showed a significant and marked variation during both the seasons. It varied from rom 175 to 435 mg catechol equi./100g during kharif-2013 and from 191 to 387 mg catechol equi./100g dring kharif 2014. The mean total phenolic content of two seasons (kharif-2013 and kharif-2014) of selected lines varied from 199 to 400 mg catechol equi./100g. During both the seasons designated B lines showed lower mean total phenolic content than that of inbred lines. On the basis of mean performance during kharif-2013 and kharif-2014 HTP 94/54, LPBL 10/112, HMS 14B and HMS 21B were identified as low total phenols containing lines whereas, DPHBL-11-123, HBL 112/H12/1011, HMS 36B and HMS 53B were identified as high phenolic containing pearl millet lines.

Their flour were stored at 15 °C and 82 % relative humidity RH for one month and changes in fat acidity (FA), activities of peroxidase (POX), lipoxygenase (LOX) and polyphenol oxidase (PPO) in control and stored flour along with change in pH of water extract of flour were monitored. Increase in FA (mg KOH/100 g d.m.) and decrease in pH of flour was maximal in pearl millet (287.5 mg KOH/100 g d.m. and 0.4) followed by maize (151 mg KOH/100 g d.m. and 0.23) and wheat (61 mg KOH/100 g d.m. and 0.1) respectively. A decline in activity of POX, LOX and PPO was observed during storage. Pearl millet flour possessed almost double activity of POX (413 Units/g d.m.) in comparison to wheat (198 Units/g d.m.) and 1.3 fold higher than that of maize (153 Units/g d.m.) and even after decrease activity of POX was higher in flour of pearl millet compared to the other two.

This investigation was carried out in view of generating breeding material for development of low rancid pearl millet hybrids/varieties. Flour of twenty-one genotypes; seven hybrids, seven CMS lines, five inbreds and two composites stored in covered aluminium boxes at 37°C for 30 days along with respective fresh flour was analysed for shelf life indicators/determinants. Crude fat content and fat acidity (FA) of fresh flour of the genotypes varied from 3.8 to 7.2% and 11 to 75 mg KOH/100 g d.m., respectively. FA in stored flour ranged between 180 and 330 mg KOH/ 100 g d.m. After storage, magnitude of decrease in pH of water extract of flour of the genotypes varied from 0.15 to 0.44. Activity of peroxidase (POX) varied from 378 to 588 units in control flour and irrespective of the genotypes decreased upon storage. Increase in FA (difference between FA of fresh and stored flour) rather total build up of FA was positively associated with crude fat content (r = 0.440*) indicated comparatively more prominent role of lipolytic enzymes. Chemical changes taking place in water soluble fraction of flour were independent of fat content as no correlation was discerned between fat content and decrease in pH. Among the hybrids, HHB 197 had lowest crude fat content (4.7%), lowest total build up FA (212 mg KOH/100 g d.m.), slowest increase in FA (191 mg KOH/100 g d.m.), least decrease in pH (0.31) of water soluble fraction flour during storage and lowest activity of POX in fresh flour (377 units/g d.m). Among all the tested CMS lines, inbreds and composites, HBL 11 showed pattern of quantitative changes in FA, pH and POX activity similar to the hybrid HHB 197 and was identified a promising inbred for developing low-rancid pearl millet variety or hybrid.

They constitute an important source of carbohydrates, protein, dietary fiber, vitamins and anti-nutrients (Katina et al., 2005). Pearl millet [Pennisetum glaucum (L) R. Br.] is an important hardy coarse cereal crop grown mostly in marginal environments in the arid and semi-arid tropical regions of south Asia and sub-saharan Africa. Pearl millet, being a C4 plant, has a very high photosynthetic efficiency and dry matter production capacity. It is usually grown under most adverse agroclimatic conditions where other crop fails to produce economic yields. In spite of this, pearl millet has a remarkable ability to respond to favorable environments because of its short developmental stages and capacity for higher growth rates, thus making it excellent crop in short growing season under

In this study role of peroxidase, lipids and phenolics in deterioration of quality of pearl millet in control and stored flour of high (HHB 94) and low (ICMA 94222 x 78/71) rancid genotype was determined. Fat content, fat acidity, free fatty acids, total phenols, C-glycosylflavones content and peroxidase activity of HHB 94 were higher than that of ICMA 94222 x 78/71. Storage of flour for 8 days of these two genotypes showed significant increase in fat acidity and free fatty acids. Storage had no effect on C-glycosylflavones content whereas peroxidase activity reduced significantly with storage time. Isozyme profile showed that pearl millet grains had 3 isozymes of peroxidase and banding pattern was similar in both HHB 94 and ICMA 94222 x 78/71. While banding intensity represented that ICMA 94222 x 78/711 had lesser peroxidase activity as compared to HHB 94. The result suggested that peroxidase activity, fat acidity and free fatty acid value were usually correlated.

Flour of twenty-one genotypes; seven hybrids, seven CMS lines, five inbreds and two composites stored in covered aluminium boxes at 37°C for 30 days along with respective fresh flour was analysed for shelf life indicators/determinants. Crude fat content and fat acidity (FA) of fresh flour of the genotypes varied from 3.8 to 7.2% and 11 to 75 mg KOH/100 g d.m., respectively. FA in stored flour ranged between 180 and 330 mg KOH/ 100 g d.m. After storage, magnitude of decrease in pH of water extract of flour of the genotypes varied from 0.15 to 0.44. Activity of peroxidase (POX) varied from 378 to 588 units in control flour and irrespective of the genotypes decreased upon storage. Increase in FA (difference between FA of fresh and stored flour) rather total build up of FA was positively associated with crude fat content (r = 0.440*) indicated comparatively more prominent role of lipolytic enzymes. Chemical changes taking place in water soluble fraction of flour were independent of fat content as no correlation was discerned between fat content and decrease in pH. Among the hybrids, HHB 197 had lowest crude fat content (4.7%), lowest total build up FA (212 mg KOH/100 g d.m.), slowest increase in FA (191 mg KOH/100 g d.m.), least decrease in pH (0.31) of water soluble fraction flour during storage and lowest activity of POX in fresh flour (377 units/g d.m). Among all the tested CMS lines, inbreds and composites, HBL 11 showed pattern of quantitative changes in FA, pH and POX activity similar to the hybrid HHB 197 and was identified a promising inbred for developing low-rancid pearl millet variety or hybrid.

They constitute an important source of carbohydrates, protein, dietary fiber, vitamins and anti-nutrients (Katina et al., 2005). Pearl millet [Pennisetum glaucum (L) R. Br.] is an important hardy coarse cereal crop grown mostly in marginal environments in the arid and semi-arid tropical regions of south Asia and sub-saharan Africa. Pearl millet, being a C4 plant, has a very high photosynthetic efficiency and dry matter production capacity. It is usually grown under most adverse agroclimatic conditions where other crop fails to produce economic yields. In spite of this, pearl millet has a remarkable ability to respond to favorable environments because of its short developmental stages and capacity for higher growth rates, thus making it excellent crop in short growing season under
