农作物杂种优势的应用,在我国已有近30年的历史。而高粱杂种优势的利用却是比较早的。高粱雄性不育系3197A 在五十年代引进我国后,到六十年代先后选育出一批杂交组合:晋杂5号、原杂10号、遗杂10号等并应用于生产,对粮食增产起了积极作用。同时对高粱植物学特征的杂种优势,如茎、株高、穗长、千粒重等,国内外的学者都进行了许多的研究,报道也不少,但对高粱籽粒品质性状的杂种优势研究见报不多。作者从1983～1985年,连续3年对高粱籽粒品质性状的杂种优势进行了初步研究,为高粱品质育种提供依据。
The application of crop heterosis in our country has been nearly 30 years of history. The use of sorghum heterosis is relatively early. After introduced into our country in the 1950s, the sorghum male sterile line 3197A bred a number of hybrid combinations successively in the 1960s: Jinza 5, Yuanza 10, Jugao 10 and so on, and applied them to the production, Played a positive role. At the same time, many domestic and foreign scholars carried out many studies on the heterosis of sorghum botanical characteristics such as stem, plant height, spike length and 1000-grain weight, and reported many reports on the heterosis of sorghum grain quality. many. From 1983 to 1985, the author conducted a preliminary study on the heterosis of grain quality traits of sorghum for three years in succession, which provided the basis for the quality breeding of sorghum.
