ARPA (HORDEUM VULGARE L.) O‘SIMLIGINING NAV VA TIZMALARIDA QURG‘OQCHILIKKA CHIDAMLILIK XUSUSIYATLARINING MOLEKULYAR-GENETIK TAVSIFI
Keywords:
arpa (hordeum vulgare) qurg‘oqchilik stressi, molekulyar genetika, markerga asoslangan tanlashAbstract
Qurg‘oqchilik stressi iqlim o‘zgarishi sharoitida don ekinlari yetishtirish samaradorligini cheklovchi asosiy abiotik omillardan biri hisoblanadi. Arpa (Hordeum vulgare L.) nisbatan qurg‘oqchilikka chidamli ekin bo‘lsa-da, nav va tizmalar orasida ushbu belgi bo‘yicha genetik farqlanish mavjud. Ushbu nazariy tezisda arpa nav va tizmalarida qurg‘oqchilikka chidamlilikni belgilovchi molekulyar-genetik mexanizmlar bo‘yicha mavjud ilmiy adabiyotlar tahlil qilinadi hamda seleksiya jarayonida qo‘llanilayotgan zamonaviy yondashuvlar yoritiladi.
