Ushbu tadqiqotda Qoraqalpog‘iston Respublikasining sho‘rlangan tuproq va suv resurslari tanqisligi sharoitiga moslashgan sholi genotiplarini seleksiyalashning ilmiy-amaliy asoslari o‘rganildi. Mintaqa sharoitida yetishtiriladigan madaniy sholi (Oryza sativa L.) ning japonica va indica kichik turlariga mansub ertapishar genotiplar hamda ularning noqulay abiyotik omillarga chidamlilik manbalari bo‘lgan yovvoyi ajdod turlar (Oryza rufipogon, Oryza nivara) seleksion va agrobiologik belgilar bo‘yicha kompleks baholandi. Tadqiqot natijasida qisqa vegetatsiya davrida (98–105 kun) yuqori hosildorlik elementlarini saqlab qoluvchi va sho‘rga chidamli dastlabki manbalar ajratib olindi.
