Approaches for Genetic Analysis of Chickpea Genotypes under Late Sown Condition

Abstract

Investigation of the genetic potential of chickpeas is crucial in order to achieve durable and high-yielding genotypes. The goal of this study is to identify the genetic potential and personality traits associated. Evaluation of thirty-six desi genotypes of chickpea under late sown condition revealed that substantial degree of variation was present, while three traits viz., Leaf pattern, flower colour, seed shape and plant pigmentation were found monomorphic, whereas foliage colour, seed surface were dimorphic,polymorphic traits were noted in leaflet size, plant growth habit, plant height, seed colouring, days to 50% flowering and days to maturity. Magnitude of genotypic coefficient ofvariations, high heritability along with high genetic advance as percentage of mean recorded forharvest index, number of seeds per plant, number of pods per plant and number of effective pods per plant.Correlation and path analysis revealed biological yield, 100 seed weight, seed per plant, harvest Index and plant height are the mostimportant characters,while imparting selection as these exhibited strong association and maximum positive direct effects on seed yield per plant.Intra cluster D2 values showed that most diverse genotypes were Phule G13110 and PG 0104, hybridization program between these genotypes may generate desirable sergeants for various yield attributing traits. Genotypes GL 12021, PG 158, PG 0104, JG 24, H 12-62, IPC 2010-134, GNG 2261, GL29098, BG 3067, IPC 2012-98, Phule G13110 and RVSSG 38 were present in more than one PCs hence contributed maximum towards yield and can be used in various breeding programmes for yield improvement under late sown condition.
