بررسی کیفیت پروتئین‌های دانه در موتانت های سویا [Glycine max (L.) Merrill]

Lectin protein is considered as an important anti-nutrient factor in soybean seed. A low quality soybean proteins is associated whit the presence of lipoxygenase protein due to its unfavorable flavor. This research was conducted at the Sari Agricultural Sciences and Natural Resources University, during 2008-2009 to evaluate the effect of Gamma rays on anti-nutrient protein of Hill cultivar. M1 generation seeds were obtained and grown as plant-to-row in next generation. In M2 generation, highly variation was observed for plant height, flower color, sterility, leaf shape, early and late maturity, that among mutant plants with favorable morphological traits were selected. After protein evaluation by SDS-PAGE it hasn't shown the lectin protein in M-107 plant mutant and also anti-nutrient factor of lectin and lipoxygenase was absence in M-729 mutant. However, these two mutant plants which hadn't shown one or several subunit proteins, but not showed meaningful commutation in total volume protein and oil content. These two mutant plants can be considered very important for improving seed proteins in soybean breeding programs.
