| Abstract | ||
| Twenty bread wheat (Triticum aestivum L.) genotypes were obtained from the Low Input Breeding Program at El Gemmeiza Agricultural Research Station. Four field experiments during two seasons 2017/2018 and 2018/2019 were done to evaluate these genotypes under normal and stress conditins at El-Mataana Agricultural Research Station. The experimental design was randomized complete block design, with three replications. Each season two experiments were done. The first experiment was represented normal conditions. Five times of irrigation with 70 Kg N/fed were used. However, the second experiment represented low input conditions two times of irrigation with 35 kg N/fed was used. The results indicated that low input had a significant effect on decreased heading and maturity dates. Results cleared that Shandaweel 1 had the best performance under both normal and low input condition. According to Stress Susceptibility Index (SSI) Misr 2 and Shandaweel 1 were considered as highest tolerant genotypes. Regarding to factor analysis two factors were identified under both normal and low input conditions. Each factor consists of the most effective characters. Results for cluster analysis obtained three major clusters of genotypes were classified under both normal and stress conditions. The first cluster which considered as high yielding genotypes was consisted of eleven genotypes namely Line 1, Line 8, Giza 171, Sids 14, Misr 2, Shandaweel 1, Line 5, Line 9, Line 7, Misr 3, and line 11 under normal conditions. Meanwhile, it consisted only of five genotypes namely Giza 171, Misr 2, Shandaweel 1, Misr3 and Sids 14 under low input conditions. | ||
