Annotatsiya. Maqolada Andijon viloyatining sug'oriladigan dehqonchilik sharoitiga mos mosh seleksion ashyolarini tanlash nuqtayi nazaridan xorijiy kolleksiya nav-namunalarining gullash va pishish muddatlari tahlil qilindi. 27 ta xorijiy namuna XN-01-XN-27 shartli kodlari bilan hamda mahalliy 'Navro'z' navi andoza sifatida baholandi. Model ma'lumotlarda 50% gullash muddati 35,3-44,7 kun, to'liq pishish 68,7-83,7 kun oralig'ida o'zgardi. XN-04, XN-09, XN-14, XN-18, XN-23 va XN-27 namunalari andozadan 3,3-6,3 kun erta pishishi bilan ajraldi. XN-14, XN-18, XN-23 va XN-27 namunalarida ertapisharlik yuqori hosildorlik bilan uyg'unlashdi. Natijalar qisqa vegetatsiya davri va mahsuldorlikni birlashtirgan genotiplarni keyingi seleksiya bosqichlariga jalb qilish uchun asos bo'la olishini ko'rsatdi.
Abstract. The paper evaluates flowering and maturity duration of foreign mungbean accessions for identifying breeding material adapted to irrigated conditions of Andijan region. Twenty-seven foreign accessions coded XN-01-XN-27 and the local cultivar 'Navro'z' as a standard were compared. In the model dataset, days to 50% flowering ranged from 35.3 to 44.7 days and full maturity from 68.7 to 83.7 days. Accessions XN-04, XN-09, XN-14, XN-18, XN-23 and XN-27 matured 3.3-6.3 days earlier than the standard. XN-14, XN-18, XN-23 and XN-27 combined earliness with relatively high seed yield and were identified as promising breeding sources.
