Correlation and Path Analysis Studies of Pod Yield and its Component Traits in Mungbean [Vigna radiata (L.) Wilczek] Genotypes

Abstract

Background: Mungbean is an important pulse crop grown in India. The mungbean is an excellent source of protein (27%) and its essential amino acid comparable with that of soybean and kidney bean. Estimates of correlation coefficient are useful in identifying the component traits which can be used for yield improvement of mungbean. Path coefficient analysis provides a thorough understanding of contribution of various characters by partitioning the correlation coefficient into components of direct and indirect effects. This study aimed to quantify the relationship and contributions of various traits to seed yield. Methods: The present investigation was undertaken to assess the correlation and path analysis on yield and its components in 38 genotypes of mungbean. The genotypes were raised in randomized block design with three replications during Kharif 2019 at Agricultural Research Station Farm, Agriculture University, Jodhpur, Rajasthan. Result: The experimental results showed that positive correlation and positive direct effect on seed yield were observed for plant height, number of pods per plant, number of seeds per pod and 100 seed weight. Therefore these traits can be used for mungbean improvement program as well as developing high yielding varieties of mungbean.
