GENETIC VARIABILITY AND ASSOCIATION PATTERN OF YIELD AND IT’S ATTRIBUTING CHARACTERS AMONG DIALLEL POPULATION OF PIGEONPEA (CAJANUS CAJAN (L) MILLS.)

A nature gifted crop Pigeonpea [Cajanus cajan (L.) Mill sp.] alternatively termed tur, arhar, etc. is manage status as leading pulse crop of India.Pigeonpea breeders are looking as important asset which genotypes are adapted broadly and favourable to input deficient as well as input intensive agriculture in demand to boost productivity and production of the crop.Research in the present context was carried out in Research-cum-Instructional Farm, Department of Genetics & Plant Breeding, IGKV, Raipur, (C.G.).Material under study subject comprised of 5 parents, 10 direct crosses and 10 reciprocals of pigeonpea using parent Rajeevlochan as check variety.The parents were crossed during Kharif 2020-2021 on 5x5 diallel fashion.Parent and F 1 's in all combinations were evaluated by utilizing Full Diallel Analysis, Method-I, Model-I, (Griffing's Approach) in Complete Randomized Block Design (RBD) by 3 replications through out Kharif 2021-2022.Observations were taken on 9 different quantitative characters.Result:The results revealed that character seed yield per plant genotypic and phenotypic coefficient of variation value indicated highest.High heritability was reported by seed yield per plant followed by 100 seed weight, primary branches/plant, number of pods per plant, plant height, shelling percentage and number of seeds per pod.Low heritability was reported by days to 50% flowering.Genetic advance estimated high on Seed yield per plant followed by number of pods per plant, primary branches per plant, 100 seed weight, shelling percentage and plant height.Heritability together with genetic advance both estimated high stated by seed yield per plant followed by primary branches per plant, plant height, 100 seed weight and shelling percentage.Heritability together with genetic advance estimated low stated by days to 50% flowering.Association analysis results reported that characters 100 seed weight and number of pods per plant showed significant positive correlation at both genotypic and phenotypic orders and seed yield per plant stated positive direct effect.Whereas, negative significant correlation days to 50% flowering at phenotypic order and seed yield per plant aid negative direct effect.
