高粱杂种优势利用是以细胞质雄性不育为前提,通过利用细胞质雄性不育的“三系”配套而实现的,也是不育化育种以及杂种优势利用的主要途径。试验对可诱导高粱雄性不育的细胞质A1、A2、A3、A4开展甜高粱细胞质雄性不育研究,对于提高杂交高粱产量、品质、种子纯度,拓宽种质资源利用范围,实现异质高粱杂交种在生产中的应用提供一定的依据。 Utilization of heterosis in sorghum is based on the premise of cytoplasmic male sterility, which is achieved through the use of “three lines” of cytoplasmic male sterility. It is also the main way of infertility breeding and utilization of heterosis. Experiments on the cytoplasmic male sterility of sweet sorghum, which can induce the male sterile cytoplasms A1, A2, A3 and A4 in sorghum, are carried out to improve the yield, quality and purity of hybrid sorghum, broaden the utilization range of germplasm resources, In the application of production to provide some basis.
