Character association and path analysis studies on seed yield and its yield attributing traits in mungbean (Vigna radiata (L.) Wilczek)

Abstract

Mungbean (Vigna radiata (L.) Wilczek) is an important pulse crop of India. It is an excellent source of dietary protein. Inter-relationship among various quantitative characters i.e days to 50% Flowering, days to Maturity, plant height (cm), primary Branches /plant, secondary Branches /plant, pods per plant, Seeds per pod, 100 seed weight (gms) were analysed with seed yield. Eight genotypes being studied at station trial at Barrister Thakur Chhedilal college of Agriculture and Research Station, Sarkanda Bilaspur, Chhattisgarh in Kharif 2014-15. Correlation analysis revealed that days to 50 % flowering has positive significant correlation with days to maturity, plant height and pods per plant. Pods per plant have positive significant correlation with plant height, secondary branches per plant and days to maturity. Plant height has positive significant correlation with days to maturity and secondary branches per plant. The path coefficient analysis revealed that days to 50% flowering, primary branches/plant, secondary branches/plant, 100 seed weight and no of seeds per pod had positive direct effect on seed yield, while plant height, days to maturity and pods per plant had negative direct effects on seed yield. Late flowering with numerous primary and secondary branches with more seed weight and more no of seeds per pod directly lead to increase in seed yield. Less pods per plant with high seeds/pods is more desirable trait for high seed yield.
