高粱“3197A”(以下简称3A),由于它的配合力较高,其杂交后代无论在产量性状还是在抗逆性等方面,都比其他一般高粱品种有较大的提高.所以,到目前为止,仍是我省高粱生产上应用最广泛的一个雄性不育系.我市杂交高粱制种和“3A”繁殖面积历年都在2万亩以上,但实收面积远远达不到这个数字,其原因除混杂报废、花期不遇和牲畜为害外,大部分是因选地不当,造成3A不能在霜前正常成熟,或遇霜冻冷害,丧失种用价值所致.
Sorghum “3197A” (hereinafter referred to as 3A), because of its higher combining ability, its hybrid offspring has higher yield than other general varieties of sorghum both in yield traits and in resistance, etc. Therefore, so far, , Is still the most widely used sorghum in our province a male sterile line.Our hybrid sorghum seed production and “3A” breeding area over the years are more than 20000 acres, but the real income area is far below this figure, The reason for this is that in addition to mixed scrapping, florescence, and livestock damage, most of them are improperly selected, causing 3A to fail to mature normally before frost or suffer frost damage and loss of species value.
