Abstract:
During 2019-20, thirty-three groundnut genotypes were evaluated in completely randomized design with three replications in controlled environment facility, ICRISAT, Hyderabad. Observations were recorded on various characters such as days to 50% flowering, days to maturity, fresh pod yield per plant, dry pod yield per plant, hundred seed weight and shelling percentage on three plants per genotype per replication in controlled environment facilities and mean were calculated. Analysis of variance revealed significant differences among the genotypes for all the traits under controlled environment facility at 0.01 and 0.05 probability levels. The correlation studies revealed that dry pod yield per plant had significant positive genotypic and phenotypic association with shelling percentage. Path coefficient analysis revealed that fresh pod yield per plant followed by hundred seed weight and shelling percentage have positive and direct effect on dry pod yield per plant. Further, studies on correlation and path co-efficient analysis revealed the importance of fresh pod yield per plant, which showed highly significant positive correlation and positive direct effect with dry pod yield per plant followed hundred seed weight and shelling percentage, thus can be used as selection criteria for effective yield improvement.
