Abstract: The morpho-physiological divergence was assessed in 44 Soybean (Glycine max L. Merrill) genotypes were studied in three groups. The objectives of the research work to evaluate the diversity of soybean genotypes at morpho-physiological traits and plant architecture linked to higher yield and their correlation among the traits. Negative and significant correlations were observed between HI and CGR, RGR, NAR, and biological yield in early duration group. However CGR of medium duration and long duration group was positively correlated with RGR, NAR, and biological yield and negatively correlation with test weight in (Medium group). HI was positively correlated with seed yield and test weight in long duration genotypes. The correlation of morpho-physiological traits showed positive correlation of plant height with HI and test weight. In yield traits negative and significant correlation was observed between chlorophyll (SPAD) value and biological yield. Genotype KDS 775 (Early) RSC10-30 (Early) NRC123 (Medium) and PS1570 (Long) have higher HI amongst their group. Genotype RVS 2010-1 (Early), KDS-975 (Early),RSC10-04 (Medium), NRC 117 (Medium), JS 20-94 (Medium) and JS 97-52 (c)( long) and RSC 10-29 (Long) have shown significantly higher seed yield amongst their respective groups. These genotypes having efficient partitioning of photo assimilates during the period of sink development.
