Abstract

Ushbu maqolada G. hirsutum L. turichi xilma-xilliklari va ularni duragaylash asosida olingan duragay avlodlarida bitta tup o‘simlikdagi ko‘saklar sonining irsiylanishi va o‘zgaruvchanligi tahlil qilingan. Tadqiqot natijalariga ko‘ra, hosildorlik ko‘rsatkichlari madaniy shakllarda ko‘proq, var. morilli (11,5 dona) va var. yucatanense (11,4 dona) shakllarida minimal qiymatlarni tashkil etdi. F1 duragay avlodlarda belgining to‘liq, to‘liqsiz va o‘ta dominantlik tarzida irsiylanishi namoyon bo‘ldi. F2 duragay avlodlarida kuzatilgan segregatsiya va irsiylanish darajasiga ko‘ra, hosildorlik belgisi bo‘yicha yuqori ko‘rsatkichga ega genotiplarni ajratib olinib, keyingi seleksion tadqiqotlar uchun tavsiya etiladi.
