Mazkur tadqiqotda rangli tolali g‘o‘za namunalari (A-800, 010108) va oq tolali Sadaf navi ishtirokida muhim xo‘jalik belgilaridan tola chiqimi, 1000 ta chigit og‘irligi hamda tola uzunligi ko‘rsatkichlari o‘rganildi. Ota-ona shakllari va F1 duragaylarda ushbu belgilar statistik tahlil qilinib, ularning irsiylanish xususiyatlari aniqlandi. Natijalarga ko‘ra, ayrim duragay kombinatsiyalarida to‘liqsiz dominantlik, retsessivlik va geterozis hodisalari kuzatildi. Ayniqsa, A-800 × Sadaf va A-800 × 010108 kombinatsiyalari ayrim belgilar bo‘yicha ijobiy natijalar ko‘rsatib, seleksiya ishlarida istiqbolli boshlang‘ich material sifatida ahamiyatga ega ekanligi aniqlandi.
