Abstract
Tadqiqotda zig‘ir (Linum usitatissimum L.) genotiplarining qurg‘oqchilikka chidamliligi laboratoriya sharoitida 15% PEG-6000 yordamida modellashtirilgan osmotik stress fonida baholandi. Tajriba distillangan suvli nazorat va PEG- 6000 stress variantlarida uch takrorlamada olib borildi. Urug‘lar dezinfeksiya qilinib, filtr qog‘ozli idishlarda 25°C haroratda 14 kun saqlandi. Asosiy baholash mezonlari sifatida ildiz uzunligi, ildiz soni va poya uzunligi tahlil qilindi. Natijalarda K-62, K-60, K-112, K-89, K- 97, K-61 va K-20 genotiplarida ildiz uzunligi nisbatan barqaror yoki yuqori bo‘ldi. K-284, K-30, K-41, K-61 va K-67 ildiz hosil qilish bo‘yicha ijobiy javob ko‘rsatdi. K-11, K-63, K- 90 va K-115 kabi ayrim genotiplar stressga sezgirligi bilan ajralib turdi. Olingan natijalar istiqbolli manbalarni dastlabki seleksion skrining uchun ajratish imkonini beradi.References
