TURLI MINTAQALARGA MANSUB KUZGI BUG‘DOY NAMUNALARINING SARIQ ZANG (PUCCINIA STRIIFORMIS F. SP. TRITICI) KASALLIGIGA CHIDAMLILIGINI FITOPATOLOGIK BAHOLASH
##submission.downloads##
Ushbu tadqiqotda turli agro-ekologik mintaqalarga mansub 50 ta kuzgi yumshoq bug‘doy (35 ta xorijiy va 15 ta mahalliy) nav
namunalarining sariq zang (Puccinia striiformis f. sp. tritici) kasalligiga chidamliligi 2023-yilda issiqxona sharoitida hamda 2024–
2025-yillarda dala sharoitida sun’iy infeksion fon yordamida baholandi. Fitopatologik baholash natijalariga ko‘ra, o‘rganilgan
namunalar orasidan 10 ta (20%) genotip mutlaq immun va 36 tasi (72%) chidamli ekanligi aniqlandi. Kasallik rivojlanish tezligi
(AUDPC) ko‘rsatkichi bilan hosildorlik o‘rtasida ishonchli manfiy korrelyatsiya (r = -0.51, p < 0.001) mavjudligi isbotlandi. KIB-
20-27 FAW-IR-157, KIB-20-27 FAW-IR-142 xalqaro tizmalari hamda mahalliy Hisorak navi kasallikka yuqori chidamliligi va
barqarorligi bilan ajralib turdi hamda kelgusi seleksiya dasturlari uchun qimmatli donor sifatida tavsiya etildi.
