我国已选育出不同质源的水稻雄性不育系30多种。本文是试图对水稻雄性不育系的分类所进行的初步探讨。按恢保关系分类:目前可以明显判断为不同质类的有野败型、红莲型和滇一型。按细胞质源分类:大致可分为种间核置换、野生稻和栽培之间的核置换、栽培稻和野生稻之间的核置换、籼稻和粳稻之间的核置换、籼稻和粳稻之间的核置换、籼籼间或粳粳间的核置换。按花粉败育程度分类:可分为单核期败育、二核期败育、三核期败育。按杂种一代的花粉可育率分类:可分为孢子体不育和配子体不育。
China has bred more than 30 different types of male sterile rice lines. This article is an attempt to investigate the classification of male sterile lines in rice. According to the relationship between the recovery and security classification: At present, it can be obviously judged as a different type of wild defeat, Honglian and Yunnan type. According to the classification of cytoplasmic sources, they can be divided into interspecific nuclear displacements, nuclear displacements between wild and cultivated rice, nuclear transplants between cultivated and wild rice, nuclear transplants between indica and japonica, between indica and japonica Nuclear replacement, indica indica or between japonica and japonica nuclear replacement. According to the degree of pollen abortion classification: can be divided into single-nuclear abortion, two nuclear abortion, trinuclear abortion. According to the pollen fertility of hybrid generation classification: can be divided into sterile spores and gametophyte sterility.
