The treatments (cropping patterns) were T1 = T. aman rice (BINA 7)-Potato-Mungbean (BARI mungbean 6) (Improved pattern), T2 = T. aman rice (BR11)-Potato-Fallow (Farmers pattern), T3 = T. aman rice (BINA 7)-Potato + Maize intercrop-Mungbean (Improved pattern) and T4 = T. aman rice (BR11)-Potato / Maize relay (Farmers pattern). The highest yield (4.16 t ha-1) was recorded in T2 (BR11) which is statistically at par with T4 (4.15 t ha-1) but higher than the other treatments. Early planting sole potato (T1) gave highest yield (26.10 t ha-1) which was significantly higher than all other treatments. Late planting sole potato (T2), intercropped early potato (T3) and relay potato (T4) showed similar yield (23.61-24.79 t ha-1). Intercropped (T3) and Relay (T4) maize did not vary significantly in the studied parameters and yields were 8.21 and 7.92 t ha-1 , respectively. Mungbean after sole potato (T1) gave higher number of pods/plant (17.25), and yield (1.47 t ha-1) which is significantly higher than those of T3 (14.89 and 1.28 t ha-1 , respectively). Highest gross return (GR) (Tk. 417720) and gross margin (GM) (Tk. 220220) were calculated in improved pattern T3 and the lowest of those (Tk. 289670, Tk. 146020) in farmers pattern T2. The other improved pattern T3 was the second highest performer considering GR and GM. But BCR (2.21) was highest in T1 and second highest in T3. The results indicated that the improved patterns (T1, T3) were better than farmers pattern (T2, T4). The improved pattern (T1) gave GR Tk. 67890 and GM Tk. 51785 higher than farmers pattern (T2). Similarly, the other improved pattern (T3) showed Tk. 51870 and Tk. 37395 higher than farmers pattern (T4). The improved pattern T1 and T3 created 45 working day job for the labour for harvesting early matured rice in the Monga/ jobless period (October) while farmers' pattern gives only 3 days work. The mungbean included improved cropping patterns can be suggested for increased production, economic return and Monga mitigation (work opportunity in off period) in Rangpur.

Significant variation was observed among all the genotypes for all the characters studied. Considering genetic parameters high genotypic coefficient of variation (GCV) was observed for number of secondary branches per plant, siliquae per plant, yield per plant, whereas days to maturity showed very low GCV. High heritability with low genetic advance in percent of mean was observed for days to maturity which indicated that non-additive gene effects were involved for the expression of this character and selection for such trait might not be rewarding. High heritability with moderate genetic advance in percent of mean was observed for plant height and days to 50% flowering indicating that this trait was under additive gene control and selection for genetic improvement for this trait would be effective. Considering, inter genotypic variability, heritability, and genetic advance, % coefficient of variation and other agronomic performance G 2 , G 14 , G 18 , G 1 , G 9 , G 12 , G 16 , G 17 may be considered to be better parents for future uses in hybridization programme.

Merrill) seeds are abundant in physiologically active metabolites, including carotenoids and chlorophylls, and are used as an affordable source of functional foods that promote and maintain human health. The distribution and variation of soybean seed metabolites are influenced by plant genetic characteristics and environmental factors. Here, we investigated the effects of germplasm origin, genotype, seed coat color and maturity group (MG) on the concentration variation of carotenoid and chlorophyll components in 408 soybean germplasm accessions collected from China, Japan, the USA and Russia. The results showed that genotype, germplasm origin, seed color, and MG were significant variation sources of carotenoid and chlorophyll contents in soybean seeds. The total carotenoids showed about a 25-fold variation among the soybean germplasms, with an overall mean of 12.04 µg g−1. Russian soybeans yielded 1.3-fold higher total carotenoids compared with Chinese and ...

To investigate the variation in seed tocopherol composition of soybeans from different origins, 493 soybean accessions from different countries (China, USA, Japan, and Russia) belonging to 7 maturity groups (MG 0–VI) were grown in 2 locations (Beijing and Hainan Provinces of China) for 2 years (2017 and 2018). The results showed that significant differences (p < 0.001) were observed among the accessions and origins for individual and total tocopherol contents. The total tocopherol content ranged from 118.92 μg g−1 to 344.02 μg g−1. Accessions from the USA had the highest average concentration of γ- and total tocopherols (152.92 and 238.21 μg g−1, respectively), whereas a higher level of α-tocopherol (12.82 μg g−1) was observed in the Russian accessions. The maturity group of the accession significantly (p < 0.001) influenced all tocopherol comp...

Selection for higher tocopherol contents in seeds along with other desirable traits is an important goal in soybean breeding. In order to identify the genomic loci and candidate genes controlling tocopherol content in soybean seeds, the bulked-segregant analysis technique was performed using a natural population of soybean consisting of 1525 accessions. We constructed the bulked-segregant analysis based on 98 soybean accessions that showed extreme phenotypic variation for the target trait, consisting of 49 accessions with extremely-high and 49 accessions with extremely-low tocopherol content. A total of 144 variant sites and 109 predicted genes related to tocopherol content were identified, in which a total of 83 genes were annotated by the gene ontology functions. Furthermore, 13 enriched terms (p < 0.05) were detected, with ...

We optimised the extraction and detection of folates from soybean seeds by HPLC-MS/MS and analysed the folate content and composition of 1074 accessions. Total folate content ranged from 64.51 to 691.24 μg/100 g fresh weight, with 10-fold variation, and 60 elite accessions with over 400 μg/100 g of total folate were identified. The most abundant component was 5-CHO-H4folate, which accounted for an average of 60% of total folate content. Seed-coat colour, seed weight, ecoregion, and accession type significantly affected soybean folate content. Furthermore, 5-CH3-H4folate correlated positively with seed protein (r = 0.24***) and negatively with oil (r = -0.26***). The geographical distribution of folate according to accession origin revealed that accessions from Northeast China contain higher amounts of total folate and 5-CHO-H4folate. This study provides comprehensive and novel insights into the folate profile of soybean, which will benefit soybean breeding for folate enhancement.

Carotenoids are applicable in pharmaceuticals/nutreceuticals, cosmetic, and mainly food industries. However, an efficient and accurate method for carotenoid and chlorophyll detection and quantification has not yet been developed and validated for soybean seeds. The need for a rapid and reliable analysis method has become increasingly important. Thus, this study was initiated to develop and validate a simple, rapid, and selective reversed-phase high-performance liquid chromatographic (RP-HPLC) method for the simultaneous determination of lutein, zeaxanthin, α-carotene, β–carotene, β–cryptoxanthin, and chlorophyll–a and –b in soybean flour sample (100.00 mg) extracted using ethanol-acetone (1:1) solvents at a volume of 1.50 mL. Interestingly, the effective separation technique was achieved using the mobile phases of methyl tert-butyl ether, methanol containing 10 mM ammonium ...

Here, we profiled the seed tocopherol compositions of 1151 Chinese soybean accessions that originated from different ecoregions, grown in three locations for two years in China. Thus, this study aimed to evaluate the effect of accessions, ecoregions of origin, accession types and geographical factors on tocopherol content of soybean as well as unveil the correlations among tocopherols and other important seed quality traits. The highest average contents of α- and γ-tocopherols (15.43 μg g-1 and 151.44 μg g-1, respectively) were observed in the Northern Region (NR) accessions of China. Also, α-, γ-, and total tocopherol contents were higher in cultivars than landraces. The correlation analysis showed that tocopherols were significantly associated with other seed quality traits. α- and γ-tocopherols had significant positive correlations with latitude and longitude, while δ-tocopherol showed a contrary trend. Taken together, we identified novel soybean accessions that can be utilized as raw materials for food industries and in breeding programs to improve the tocopherols contents of soybean seeds.
