Abstract
The research was done to study the genetic diversity and heritability for high yield and yield related parameters in18 accessions desi chickpea (Cicer arietinum L.) at experimental research area of Agriculture Research Institute (ARI) Ratta Kulachi, D. I. Khan during Rabi season 2017-2018 in RCB design with 3 replications along with two check genotypes i.e Bhakkar 2011and Bittle 2016. The results depicted the significant differences among all the accessions of chickpea i.e. days to germination with 5.18% coefficient of variation (CV). Grains Pod-1, Primary Branches plant-1 and plant Height (cm) were also found highly significant. The values of (PCV) were higher than the genotypic (GCV) depicted the interruption of environment on chickpea attributes. (GCV) was low for almost all the traits while its values were moderate for secondary branches plant-1 and high for grain yield plant -1. (PCV) low for almost all the traits while its value is moderate for no. of primary branches plant-1 100 seed weight and grain pods-1 and high for grain yield plant-1 and secondary branches plant-1. Heritability for days to germination, plant height and primary branches plant-1, days to 50 flowering, secondary branches plant-1 and grain yield plant-1 were high due to positive variation. The said experiment from analysis showed that accession code (CH10/12) was found for early days to germination and accession code (CH32/12) was noted for minimum days to 50% flowering, maximum plant height (cm) while accession code (CH44/12) was found for maximum no. of grains pod-1. Hence the said accessions code (CH10/12), (CH32/12), (CH14/12) and (CH44/12) have the best performance with significant variation in the terms of genotypic coefficient of variation (GCV), phenotypic coefficient of variation (PCV), variance of genotypic variation (GV), phenotypic variation (PV), environmental variation (EV), high heritability and low genetic advance among all the accessions. Therefore the said accessions should be used as parental crosses for producing new high yielding cultivar through further chickpea breeding programme for the agro ecological zone of Dera Ismail Khan, KPK, Pakistan.
