The success of good breeding program usually depends upon the genetic variability present in the breeding materials, however, spatial and temporal studying on the amount, kind and magnitude of variability as well as genetic relationship of traits are not efficiently exploited yet. The present investigation was designed to assess the extent of variability, genetic advance, heritability and interrelation of different traits of 100 chickpea genotypes using triple lattice design in Takusa district, North Gondar, Ethiopia, during 2018/19 main cropping season. The examined genotypes were highly significant for all studied traits. The magnitude of genotypic and phenotypic coefficient of variation indicated the presence of variability among advanced lines. The trait above ground biomass exhibited the highest range of variability followed by grain yield, number of pods per plant, hundred seed weight, days to flowering and days to maturity. The highest estimates of genotypic and phenotypic coefficient of variation were exhibited grain yield followed by number of pods per plant, number of secondary branches per plant, above ground biomass, and harvest index. The highest broad sense heritability coupled with high Amare Tsehaye ABOUT THE AUTHORThe Author was born on 03, October 1988 in North Gondar of Amhara Regional State, Ethiopia. As soon as he reached the age for schooling, he attend his education and joined Debre Birehan University and graduate with B.Sc. degree in plant science. Soon after, the Author was employed at Amhara Agricultural Research Institute (AARI), Gondar agricultural research center, North Gondar, Ethiopia, as sorghum and chickpea breeder. Now he completed his master of science in plant breeding at Bahir Dar University and working as chickpea breeder at Amhara Agricultural Research Institute, Ethiopia. During his stay he had generated more than 10 research proposals and published more than 3 research activities in Known journals.
