| dc.description.abstract | In the present study, a total of 36 kabuli chickpea genotypes consisting of two tolerant check genotypes pooled from ICRISAT, !CARDA and Debre Zeit Agricultural Research Center were evaluated under field experiment.for their agronomic and drought tolerant performances. All of the tested genotypes under field condition was further evaluated in Polyvinyl chloride cylinder (PVC) experiments for the evaluation of their root traits. The field trial was made in "Lattice design" in both stressed and non stressed condition with two replications for each set of experiment at Kobo in 2013. The PVC experiment was conducted by using randomized complete block design with three replications. Significant variation (P < 0. OJ) was observed for all evaluated traits of chickpea genotypes under field and PVC experiments. The highest yield under moisture stressed and non stressed conditions offield experiment was obtained by Koba and X07TH- 21-2. Among the tested genotypes !CCV- 11305 (58 gram) and !CCV- 11307 (54 gram) recorded the maximum seeds weight KOBO, EJERE, J-JABRU, AKURl YELBE, X07TH-21-2, JCCV-07313 and !CCV- 11306 expressed theit maximum potential of root length under PVC environment. Harvest index, biomass, number of pods and seeds per plant showed the highest positive and significant correlation with grain yield under stressed condition offield experiment. Higher heritability and genetic advances was obtained on grain yield, number of pods and seeds per.plant, harvest index, number of secondary branches per plant and days taken to maturity. The traits, which revealed high amount of heritability and genetic advance were controlled by additive genes, which advocated the chances of the improvement. Differences were observed among genotypes in their reactions to drought based on drought susceptibility index (DSI), yield stability index (J'S!) and tolerance index (TOL) under field condition. As the overall performances, genotypes KOBO, ICCV-09-307, X07TH-Jl82 and !CCV- 92311 were the superior genotypes due to their early phenology, higl, yield and deep rooted potential as well as their large seed and drought tolerance characters and KOBO variety has to be recommended for breeding materials and production since it was released variety. | en_US |
