Variability and stability analyses for yield and related traits of baby corn (Zea mays L.) genotypes grown under NE region of India

Abstract

Baby corn is gaining preference as a vegetable across different parts of India but the availability of varieties specific to baby corn purposes is limited. To increase production, it is essential to study the variability and stability of genotypes that can be used for baby corn purposes across different environments. Assessment of genetic variability among 12 baby corn genotypes for nine quantitative traits revealed that days to 50% silking and cob weight are essential traits for increasing baby corn yield. Environment plays a predominant role in determining the stable performance of genotypes. AMMI and GGE biplot analysis provided a clear idea of genotype and environment interaction. The results of the present study showed the influence of environments on the evaluated genotypes across seasons. Which- won- where biplot revealed that pre kharif season was better for higher baby corn yield and also the genotype GAYMH-4 was stable across the three evaluated environments with respect to baby corn yield without husk.
