几年来,我们在芝麻育种工作中,通过测定,发现两个或两个以上的不同类型的芝麻品种进行杂交所产生的后代,特别是第一代,同它的亲本相比,其生活力、抗逆性、产量和含油量等方面都有明显的提高,具有一定的杂种优势,其中有些组合的杂种优势较强。1974年,我们在繁育1973年做的杂交组合时,发现“尉氏柳条青×柘城叉子芝麻”、“开封狸芝麻×湖北观音麻”等4个组合杂种优势比较强,植株生长旺盛,分枝性强,结蒴稠密,蒴大粒饱。以“尉氏柳条青×柘城叉子”为例,该组合比母本增产97.7%,比父本增产48.3%。我县郭楼公社高平寺生产队科研组,1976年配制“70—048×驻芝 Over the past few years, we sesame breeding work, determined by testing and found that two or more different types of sesame breeds produced by the generation of offspring, especially the first generation, compared with its parents, its viability, Stress resistance, yield and oil content have obvious improvement, with some heterosis, some of which heterosis is strong. In 1974, when we breed the hybrid combination made in 1973, we found that four combinations of “Weishi wicker green × Tancheng fork sesame”, “Kaifeng raccoon × Hubei Guanyin Ma” had stronger heterosis, and the plants grew vigorously. Strong branches, dense knot bolt, bolt big grain full. For example, “Weishi wicker green × Yuncheng fork”, for example, the combination increased 97.7% than the female parent, 48.3% increase over the father.
