بررسی خصوصیات زراعی و عملکرد دانه ژنوتیپ های گندم دوروم در آزمایشات مقایسه عملکرد در مناطق معتدل دیم

In this project, 134 durum wheat genotypes in preliminary yield trial (PDYT) and 22 genotypes in advanced yield trial (ADYT) were evaluated. Results showed the existence of genetic variaon among genotypes. In PDYT, 50 genotypes had 1% to 72% superiority than the mean yield of the checks (mean= 2250 Kg/ha). 51 superior genotypes were varied for grain yield from 2273 to 4073 kg/ha. In ADYT, the line No. 8 had 7% superiority than the Saji's cultivar, but no superior genotypes than the bread wheat check (Sardari). Evaluation of genotypes for biotic (diseases and pests) and abiotic (cold) stresses showed that the genotypes were resistant to the mentioned stresses.
