Annotatsiya. Suv tanqisligi soya o‘simligining fotosintetik faolligi, suv almashinuvi, oksidlovchi stressga javobi, hosil elementlari hamda urug‘ tarkibidagi oqsil va moy miqdoriga sezilarli ta’sir ko‘rsatadi. Shu sababli qurg‘oqchilikka chidamli genotiplarni tanlashda faqat hosildorlikka tayanish yetarli emas. Mazkur tezisda soya genotiplarini suv tanqisligi sharoitida baholash uchun nisbiy suv miqdori, xlorofill holati, fotosintez, prolin, malondialdegid, antioksidant fermentlar, don tarkibidagi oqsil va moy miqdori hamda moy mahsuldorligini birgalikda qo‘llashning ahamiyati yoritilgan. Kompleks baholash genotiplarning stressga javobini chuqurroq tavsiflash va seleksiya uchun istiqbolli shakllarni aniqroq ajratishga imkon beradi.
