اثر تنش شوری بر عملکرد و اجزای عملکرد ارقام بومی گندم ایرانی

To study the effects of salinity on yield and its related traits of native resistant varieties of wheat, a factorial experiment was conducted in a completely randomized design with three replication. Genotypes and three salinity levels including (controls, 7,14,21 dS/m) were considered as the first and the second factors, Of seed weight and seed yield were recorded at 10 days after pollination. The results indicated that with increasing salinity, the number of seed weight and seed yield decreased in salinity of 21 dS/m has negative impact on plant. the results showed that the genotype KC4862 and KC4604 had respectively higher amounts of grain. The genotype KC4551 The highest number of grains per spike and seed weight, respectively.
