目前,已见报导的棉属野生种共有35个,其中有的抗病虫,有的耐旱,耐寒或耐盐碱,有的无蜜腺或无棉毒素,有的具有高品质纤维的潜力,有的茎叶坚韧,遇到台风,植株不易倒伏,叶片不易破碎。所以,野生棉种是很宝贵的种质资源,在棉花育种上有很大的利用价值。我们选用陆地棉(G.hirsutum)“河南79”作母本,以非洲异常棉(G.anomalum)作父本,进行常规杂交,再配合其他措施,获得了杂种,并已培育出F_4代植株。 At present, 35 species of cotton genus have been reported. Some of them are resistant to pests and diseases, some are drought-resistant, cold-tolerant or salt-tolerant, some are non-nectary or cotton-free toxins, and some have the potential of high-quality fibers Some tough leaves, typhoons encountered, the plant is not easy to lodging, the leaves are not broken. Therefore, wild cotton species is a very valuable germplasm resource, which has great value in cotton breeding. We selected G. hirsutum “Henan 79” as the female parent and G.anomalum as the male parent to carry out conventional crossbreeding and other measures to obtain hybrids. F4 generation plants have been bred .
