一、前言随分子遗传学的发展,农、园作物的雄性不育系育种,以提高杂种优势,提高产量和品质的理论研究,日益进展,对雄性不育系的原因及其机制,已多所阐明。下图示典型的正常的雄性可育的禾本科植物花粉母细胞和典型的雄性不育性的花粉母细胞的细胞质遗传。根据70年代植物雄性不育系的核质多系统,多基因平衡理论公式及三(四)系育性基因遗传式,可以较准确地鉴定、测定和创造两系、三系进行配套。
I. INTRODUCTION With the development of molecular genetics, the male sterile line of agriculture and garden crops breeding, in order to improve the heterosis, increase the yield and quality of the theoretical research, the progress of the male sterile lines of reason and mechanism, have more Clarified. The cytoplasmic inheritance of typical normal male-fertile gramineous pollen mother cells and typical male-sterile pollen mother cells is shown below. According to the multi-gene system of nuclear multi-gene, multi-gene balance theory and three (Ⅳ) genetics of plant sterility of male sterile lines in the 1970s, it is possible to identify, measure and create two-line and three-line systems more accurately.
