Assess morphological and genetic diversity across 27 advance breeding lines and varieties of brinjal to identify favorable traits and selection indices for breeding programs.
Evaluated 11 morphological and 16 quantitative traits across 27 advance brinjal breeding lines and varieties in the Eastern Gangetic Plains of India.
Calculated the Shannon-Wiener diversity index and estimated genotypic coefficient of variation, heritability, and genetic advance across traits.
The overall mean Shannon-Wiener diversity index was 0.733, with the widest phenotypic variation observed in fruit color, curvature, shape, and growth habit.
Genotypes BCB-40, Bidhan Super, and Garia achieved the highest marketable fruit yield, whereas SM-6-6, Arka Nidhi, and 13/BRBW RES-3 showed the lowest fruit borer infestation.
High genotypic coefficient of variation, heritability, and genetic advance occurred for yield, fruit count, fruit weight, sugar contents, and borer resistance, confirming predominant additive gene action.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Agronomic evaluation demonstrates high genetic diversity and additive gene action in brinjal varieties, suggesting early generation selection can effectively optimize yield and borer resistance.
