dc.description.abstractThe present investigation entitled “Character Association and Path Analysis in Groundnut (Arachis hypogaea L.)” was conducted with 24 genotypes (including three checks namely UG-5 (Pratap Raj Mungphali), PM-2, GG-7) during Kharif- 2015 at the Instructional Farm, College of Technology and Engineering, Maharana Pratap University of Agricultural and Technology, Udaipur. The genotypes were planted in a randomized block design with three replications. The observations were recorded for 12 characters viz., days to 50% flowering, days to maturity, plant height, number of pods per plant, dry pod yield per plant, kernel yield per plant, 100-kernel weight, sound mature kernel, shelling out turn, seed oil content, number of kernels per pod and weight of single pod on five randomly selected plants from each genotype in all the replications while days to 50% flowering and days to maturity which were recorded on plot basis and average value was subjected to analysis of variance, estimation of variability parameters, correlation and path coefficient. The estimates of genotypic parameters revealed that differences between the estimates of GCV and PCV were found least for most of the characters. Higher estimates of GCV were observed for number of mature pods per plant. Maximum heritability was found for plant height. While, maximum genetic gain was observed for number of pods per plant followed by weight of single pod. Association estimate revealed that dry pod yield per plant was positively correlated at both genotypic and phenotypic levels with kernel yield per plant , number of pods per plant, plant height, 100-kernel weight, sound mature kernels shelling percent and number of kernels per pod. Similarly, kernel yield per plant also showed positive correlation with dry pod yield, at both genotypic and phenotypic levels. Present experimental findings revealed that characters, number of mature pods per plant and weight of single pod, showed high GCV, heritability and genetic gain. Hence, selection can be made for improvement of these characters. Path coefficient analysis revealed maximum direct effect by kernel yield per plant (1.05) with dry pod yield per plant. Such an association may used for more effective breeding programmesen_US
