目前,配制高粱杂交种所利用的雄性不育系仍以3197A为主。此不育系自1956年从国外引进至今已有二十六年之久,明显地表现出配合力降低、种性退化、抗逆性减退等缺点。因此,选育或引用综合性状优于3197A的新不育系是目前高梁育种工作者的当务之急。近年来,我们引进了一批国内外新不育系。为了明确这些不育系在生产上的利用 At present, the male sterile lines utilized in the preparation of sorghum hybrids are still mainly 3197A. This male sterile line has been introduced from abroad for about 26 years since its introduction in 1956. It clearly shows the disadvantages such as the decrease of combining ability, the degeneration of species and the decrease of stress resistance. Therefore, selecting or referencing new CMS lines with better integrated characters than 3197A is the most urgent task of sorghum breeding workers at present. In recent years, we have introduced a number of new CMS lines at home and abroad. In order to clarify the use of these sterile lines in production
