Morphological Characterization, Variability and Diversity among Vegetable Soybean (Glycine max L.) Genotypes

Area of Science:

• Plant genetics
• Agricultural science
• Soybean breeding

Background:

• Vegetable soybean production requires superior varieties with enhanced traits.
• Understanding the quantitative genetics of vegetable soybean is crucial for breeding programs.

Purpose of the Study:

• To reveal the quantitative genetics of vegetable soybean genotypes.
• To estimate genetic variability and divergence of main morphological traits.

Main Methods:

• Estimation of genotypic variation (GV) and phenotypic variation (PV).
• Assessment of heritability (h²) and genetic advance percentage mean (GAM).
• Cluster analysis to determine genetic diversity among genotypes.

Main Results:

• Significant genetic variability and divergence were observed in morphological traits.
• All traits exhibited high heritability (h²) and high genetic advance percentage mean (GAM).
• Eight clusters were identified, with clusters VIII and I showing maximum diversity; genotypes GM-6 and GM-27 were highlighted for high yield traits.

Conclusions:

• Variable traits in vegetable soybean possess high potential for genetic improvement.
• Genotypes GM-6 and GM-27 are suitable for commercial cultivation.
• Other identified genotypes can serve as valuable breeding lines for future vegetable soybean development.
