Abstract
Ushbu ishda arpa (Hordeum vulgare L.) nav va tizimlarida qurg‘oqchilikka chidamlilik bilan bog‘liq xo‘jalik va morfologik belgilarni molekulyar-genetik markerlar yordamida tavsiflash yondashuvi bayon etilgan. Tadqiqot uchun 17 ta arpa genotipi tanlangan bo‘lib, ular bo‘yicha don hosildorligi, boshoqdagi donlar soni, 1000 dona don massasi, boshoqlash muddati va o‘simlik bo‘yi kabi belgilar bilan assotsiatsiyalangan SSR markerlar paneli shakllantirildi. Markerlar 2H–7H xromosomalarda joylashgan bo‘lib, panelda Bmag, GBM, GMS, EBmac, Scssr, gwm, wmc va gpw oilalariga mansub markerlar mavjud. Mazkur panel fenotipik baholash natijalarini molekulyar ma’lumotlar bilan birlashtirish va qurg‘oqchilikka chidamlilikning genetik komponentini aniqlash uchun qo‘llanishi mumkin.
