Abstract

Navoiy ilmiy-tajriba stansiyasida “Bacillus thuringiensis” (Bt) texnologiyasini tadbiq etish orqali ko’sak qurtiga va glifosatga bardoshlilik genini mahalliy g‘o‘za navlariga o‘tkazish imkoniyatlarini oshirish maqsadida Xitoyning XLZ-52 g‘o‘za navini янги mahalliy “S-01, Sharofat, SP-0655, SP-03, Sulton, S-6577, S-6601, S-8292, SP-0656, SP-04 va Buxoro-8” g‘o‘za navlari bilan o‘zaro chatishtirib olingan F1 duragaylarda bekkross chatishtirish ishlari olib borildi.


Ko‘sak qurtiga bardoshlilikning qo‘shaloq Bt genlari (CRY1AC va CRY2AB) va gerbitsidga bardoshlilikning (4EPSPS) genini mahalliy g‘o‘za navlariga o‘tkazish uchun xorijiy “XinLuZao-52” g‘o‘za navi jami 11 ta mahalliy navlar bilan chatishtirib olingan F1 duragaylarda o’tkazilgan bekkross chatishtirish natijalari, hosildorlik ko’rsatkichlari, qimmatli xo’jalik belgilarining samaradorligi o’rganildi.


Natijalar XLZ-52 navining duragaylashdagi yuqori kombinativ qobiliyatga ega ekanligini va sifatli tola yetishtirishda istiqbolli genetik resurs sifatida qo‘llanishi mumkinligini ko‘rsatdi.
