Genotypic correlation studies enable breeders to assess the inherent pattern relationship between various traits since it is based on heritable traits. The genotypic correlation for 40 greengram germplasm for 10 quantitative traits viz., days to 50 per cent flowering, number of branches/plant, plant height (cm), number of clusters/plant, number of pods/plant, number of pods/cluster, number of seed/pod, pod length (cm), single plant yield (g) and hundred seed weight (g) were evaluated at two different centers viz., Agricultural College and Research Institute, TNAU, Madurai (kharif 2012 and rabi 2012), and Agricultural Research Station, TNAU, Vaigai Dam (kharif 2012). The correlation of yield and yield contributing characters indicated that seed yield/plant was positive and significantly associated with days to maturity, plant height, number of pods/plant, number of seeds/pod and hundred seed weight. Hence, characters such as plant height, numbers of pods/plant, number of branches/plant, number of clusters/plant and number of seeds/pod has to be given importance during the selection programme to improve the yield potential of the crop.

Genetic improvement through induced mutation was found to be very effective for induction of variability in the quantitative and qualitative characters. The mutagenic effect of gamma rays (200Gy, 300Gy and 400Gy) and Electron beam (200Gy, 300Gy and 400Gy) alone or in combination (200+200Gy, 300+300Gy and 400+400Gy) on frequency and spectrum of chlorophyll and micromutations in cultivar, ADT 3 and CO 6 of blackgram was studied. Micro and macro-mutants play an important role to assess the effectiveness of the mutagens. The individual treatment of electron beam was found to be more efficient than gamma rays and combined treatment to induce chlorophyll mutants. Five different types of chlorophyll mutants such as, chlorina, albino, xantha, viridis and xanthoviridis in M2 generation were observed. The chlorophyll mutants were scored from 7 to 10 days after sowing. Among the chlorophyll mutat...

This crop has enough genetic diversity both for quantitative and qualitative characters. The qualitative traits using minimal descriptors was developed by NBPGR. Enough work had been done in characterising the greengram using quantitative characters. In this study, fifteen qualitative characters were chosen for phenotyping the 40 greengram germplasm. The fifteen characters Early plant vigour, Plant growth habit, Leaf colour, Terminal leaf length (cm), Leaflet shape, Plant surface, Branching pattern, Flower colour, Leafiness, Flowering tendency, Raceme position, Pod pubescence, Pod colour, Seed colour, Hypocotyl colour. The crop was raised in Randomised Block Design with three replications at AC & RI, Madurai during kharif 2012. The data was subjected to statistical analysis and the results revealed that 40 greengram genotypes were grouped into six clusters at 40% level. The variety ADT 1 is the distinct one differing from the other genotypes studied. It could be inferred from the present study that the geographical origin of most of the greengram germplasm is from the southern states of India having enough genetic variability in germplasm.

The individual plant and plant-row selections were made in M2, M3 and M4 generation of MDU 1 and VBN (Bg) 4. Mutant population was screened for YMV resistance, pods protruding up above the canopy, early maturity, and purple pigmentation on plant. The investigation revealed that ACM-16-30, ACM-16-29, ACM-6-17 and ACM-16-14 mutant lines were found to be as ideal mutant lines for further improvement programme. The mutants line had YMV resistance, purple pigmentation on leaf, hypocotyls, stem and pod along with pods protruding up above the canopy, good batter quality and bold seeded type.

In order to develop a determinate type and improved batter quality, MDU 1 and VBN (Bg) 4 blackgram seeds were treated with different doses (100 Gy, 200 Gy, 300 Gy, 400 Gy and 500 Gy) of gamma rays. Methods: Uniform sized seeds treated with different mutagenic doses were raised in randomised block design which constitute M1 generation. Each plant was harvested individually and forwarded to M2 generation following plant to progeny row method. The determinate types were selected from M2 generation and forwarded to further generations. After attaining homozygosity in the advanced generation, the mutants were checked for its biochemical characters (Total solubule protein content analysed by kjeldahl method, albumin and globulin analysed by Lowery’s method, arabinose content analysed by Bial method.

Wilczek) occupies a unique position in Indian agriculture and has been grown under various agro-ecological conditions. It is cultivated in 1.61mha with production of 3.38MT and productivi-ty of 474kg/ha in India. Mungbean pods are thin and brittle when dry, so shattering is a major problem. The loss of seeds by pod dehiscence is one of the major reasons for low yield in mungbean; thus, reducing the frequency of pod dehiscence is an important objective in mungbean breeding. Induced mutations, have offered a single and short alternative to conventional breeding including isolation, screening, selection and testing generation after generation. In this study, variability was induced by gamma rays and Ethyl methane sulphonate (EMS) in two greengram geno-types viz., CO (Gg) 7 and NM 65. Screening for pod shattering was carried out in M2 and M3 populations of green-gram. The scoring for shattering was recorded at physiological maturity of the pod. The shatteri...

Wilczek] is a cheap source of dietary protein for the poor, with high levels of folate and iron compared with many other legumes. Mungbean yellow mosaic virus is also one of the destructive viral disease affecting yield potential of greengram both quantitatively and qualitatively. Induced mutations, have offered a single and short alternative to conventional breeding including isolation, screening, selection and testing generation after generation. An investigation was carried out in two mungbean genotypes viz., CO (Gg) 7 and NM 65 treated by two mutagens viz., gamma rays at the doses of 300, 400 and 500 Gy and EMS treatments of 10, 20 and 30 mM. The trial was conducted in the research farm of Agricultural College and Research Institute, TNAU, Madurai during Kharif season 2013. The M 2 generation was raised as individual M 1 plant basis. The treated and control populations of M 2 generation were carefully screened for pod shattering resistance. The yellow vein mosaic virus disease (YMV) incidence was recorded for all the plants in M 3 generation for the selected 22 mutants. Based on field scoring, the mutants viz.
