Abstract
Sixty-four chickpea genotypes introduced from ICARDA were evaluated with the commercial cultivars Giza-1 for yield and some components (water regime and rainfall) during two growing seasons (2002/03and 2003104) at Maryout and and 2003/2004 seasons EI-Maghara Research Stations, Desert Research Center.
Seed yield and some components were subjected to phenotypic stability analysis according to the procedure proposed by Eberhart and Russell (1966). The results indicated that a wide range of variability betw_een two locations and high genotypic differences were detected. The genotype x environment interaction was significant and a major portion of this was accounted by the deviation from linear response. Seed yield and some components influenced by the two supplemental irrigations. The highest values of these traits were obtained when chickpea plants were irrigated for two times. This out yielded for seed yield per plant by 436.19 and 134.18% at Env.2 and Env.1 (only one irrigation at sowing with seasonal rainfed) and 55.02 and 151.59% at EnvA and Env.5 (under intervals drip irrigation).
Genotypes no. 1,2,5,10,15,29,30,39,Giza-1 and 44 gave the highest values for all traits, whereas genotypes no.20, 12,11 and 14 as well as genotypes no.11, 5,3,4,36,43,42,33 and 34 recorded the highest values for DSl1 and DSI2 respectively. Also, genotypes no.1, 5,8,23,36 and 46 were more stable for seed yield and some components compared with the other genotypes and the commercial.
Finally, genotypes no.5 and 1 are consider the best genotypes because they more stable and highly drought tolerant.
