两性花类型黄瓜是用来作为雌型黄瓜制种的有效方法。我们用自己先前育成的‘铁皮青’雌性系与雄花两性花品种‘柠檬’杂交和多次回交,育成了长果形的两性花黄瓜新品系,并证实了它在黄瓜育种上的使用价值。这类长果形两性花黄瓜的长度近20cm,长势强健。以纯合基因型雌性系与之配制的杂交组合,一般植株都是全雌的表型,因而完全适用于三交种的制种要求;而由杂合基因型的雌性系与雄花两性花类型材料所配制的杂交组合,在夏秋栽培条件下,植株会有较多的雄花出现。雌性系×两性花系×普通品种所配制的三交种,果实长度因杂交亲本而异,通常都在25-30cm以上。这样的瓜长基本符合市场的需要。
Bisexual flower type cucumbers are used as an effective method of producing female cucumbers. We breed a long fruit-shaped bisexual cucumber line by crossbreeding with ’Lentin’, a male sterile line of ’Tiepiqing’ that we previously bred, and several backcrosses with male flowers of both sexes, and confirmed its value in cucumber breeding. Such long fruit bisexual cucumber length of nearly 20cm, growing strong. Homozygous genotypes of female lines and the preparation of the hybrid combination, the general plant is the whole female phenotype, which is fully applicable to the three cross seed production requirements; and heterozygous genotypes of female and male flowers bisexual type material The hybrids prepared in summer and autumn under cultivation conditions, plants will have more male flowers appear. Female × bisexual × common varieties of the three cross-breeding species, the length of the fruit due to hybrid parents vary, usually more than 25-30cm. This long melon basically meet the needs of the market.
