Abstract
Mazkur maqolada 20 ta yeryong‘oq navining nazorat va qurg‘oqchilik fonlarida hosildorlik hamda urug‘ tarkibidagi yog‘ miqdori bo‘yicha farqlanish xususiyatlari tahlil qilindi. Qurg‘oqchilik stressi o‘simliklarda suv almashinuvi, fotosintez jarayoni, assimilatsiya mahsulotlarining urug‘ga yo‘naltirilishi va yog‘ to‘planishiga ta’sir ko‘rsatib, hosil va urug‘ sifati pasayishiga olib kelishi mumkin. Shu sababli suv tanqisligi sharoitida hosildorlik va yog‘ miqdorini barqaror saqlaydigan navlarni aniqlash muhim ilmiy-amaliy ahamiyatga ega. Hosildorlik va yog‘ miqdorini birgalikda baholash qurg‘oqchilikka nisbatan istiqbolli navlarni ajratish hamda ularni seleksiya jarayonida boshlang‘ich material sifatida tavsiya etish imkonini beradi.References
