利用杂交技术,把野生棉抗病、抗虫,纤维高品质等有益性状转移到栽培棉种,是扩大种质来源的一个重要途径。近年来,我国有些单位也先后开展种间远缘杂交,并获得了几个具有特殊性状的杂种。有关野生棉及其在杂交育种上的利用,尚有许多基本问题有待解决,至为密切。本文试从花器官形态特征、开花习性和花粉生活力等方面作概括介绍,仅供参考。 1980～82年,共观察16个野生棉种。棉种名及起源地见表。
The use of hybridization technology, the wild cotton disease resistance, insect resistance, high-quality fiber and other beneficial traits transferred to the cultivation of cotton, is to expand the source of germplasm is an important way. In recent years, some units in our country have also carried out interspecific distant crosses, and obtained several hybrids with special traits. There are still many basic issues that need to be resolved about the use of wild cotton and their hybridization and breeding patterns. In this paper, the morphological characteristics of flower organs, flowering habits and pollen viability are briefly summarized for reference purposes only. From 1980 to 1982, a total of 16 wild cotton species were observed. Cotton seed name and origin to see the table.
