Correlation and path analysis for seed yield and components traits in mungbean under arid environment

Abstract

A field experiment with 79 genotypes of mungbean was conducted at Swami Keshwanand Rajasthan Agricultural University, Bikaner during Kharif-2017 to study the correlation and path coefficient analysis for seed yield and its component traits. Significant differences were observed among genotypes for all 11 characters studied. Number of pods per plant, biological yield per plant, harvest index, number of seeds per pod, 100 seed weight and pod length had significant positive correlation with seed yield and also directly contributed towards seed yield. In addition to these traits, plant height and days to 50 per cent flowering also had direct effect on seed yield in mungbean. Therefore, selection based on these component traits would results improvement in seed yield of mungbean.
