Abstract
Mazkur tadqiqotda turli rangli tolali g‘o‘za genotiplari va oq tolali navlar ishtirokida olingan F₁ duragaylarda asosiy morfo-xo‘jalik belgilarining namoyon bo‘lishi hamda irsiylanish xususiyatlari o‘rganildi. Tadqiqotlarda qo‘ng‘ir tolali 02408 va 08814, yashil tolali 04511 va 011283 genotiplari hamda oq tolali Buxoro-6, Buxoro-102, L- 001, L-100 va S-01 navlari ishtirok etdi. Asosiy poya balandligi, ertapisharlik, ko‘saklar soni, bir ko‘sakdagi paxta massasi va bir o‘simlikdagi paxta hosili kabi belgilar baholandi. Natijalar ayrim duragay kombinatsiyalarida ijobiy dominantlik, boshqalarida esa salbiy dominantlik kuzatilganligini ko‘rsatdi. Asosiy poya balandligi bo‘yicha 010444 × L-001, L- 100 × 011283 va 04511 × Buxoro-102 kombinatsiyalari, ertapisharlik bo‘yicha esa S-01 × 08814 hamda 04511 × Buxoro-102 kombinatsiyalari istiqbolli natijalarni namoyon etdi. Bir ko‘sakdagi paxta massasi bo‘yicha Buxoro-102 × 04511 va S-01 × 08814 kombinatsiyalarida ijobiy dominantlik aniqlandi. Olingan natijalar rangli tolali g‘o‘za genotiplaridan yuqori hosildor, ertapishar va qimmatli xo‘jalik belgilariga ega yangi seleksion materiallar yaratishda samarali foydalanish mumkinligini ko‘rsatdi.References
