１９９０～１９９５年５年６季试验结果，各季矮败小麦不育株高为４４．６７ｃｍ、５６．６０ｃｍ、６６．５９ｃｍ、６６．０８ｃｍ、５４．５５ｃｍ和３７．６１ｃｍ，平均６１．５７ｃｍ，仅及可育株平均数的三分之二。不育株和可育株的比数为１：０．８９、１：１．２９、１：１．１７、１：１．１５、１：１．１０和１：１．１５，平均为１：１．１４，高秆株略多，Ｘ２测定结果，除个别例外，两类单株比数符合１：１。花器特征特性如同太谷核不育小麦，未出现变异类型。环境因素可一定程度上影响不育株和可育株的高度，但不能改变二者之间的相对关系。矮败小麦矮秆性和不育性的连锁遗传是稳定的，１９９０～１９９２年３年定株测量拔节至抽穗阶段的株高，前后期高度相关，表明从拔节期开始，可以根据植株高矮预测育性。１９９３年进一步验证了早期预测育性的效果。矮败小麦后代不育株和可育株株高等性状都会分离，但株内分离仍小于株间分离，故在后代种植方式上，经一定轮选世代，部分不育株采取株行种植，有利于提高田间选择效率。用晋麦２１４８连续回交４次，可育株综合性状接近回交父本，株高趋于一致，不育株除植株较矮外，其他性状也类似父本。、０．８９３５、０．８５０１。在此基础上，?
From 1990 to 1995, the results of five years and six seasons showed that the plant height of dwarf wheat was 44.67cm, 56.60cm, 66.59cm, 66.08cm, 54.55cm and 37.61cm, with an average of 61.57cm, Only two-thirds of the average number of fertile plants. The ratio of sterile to fertile plants was 1: 0.89, 1: 1.29, 1: 1.17, 1: 1.15, 1: 1.10 and 1: 1.15 with an average of 1 : 1.14, tall stalks slightly more, X2 test results, with a few exceptions, the ratio of two types of plants in line with 1: 1. Floral characteristics as Taigu nuclear sterile wheat, there is no type of mutation. Environmental factors may affect the height of sterile and fertile plants to a certain extent, but can not change the relative relationship between the two. The dwarfing wheat dwarfness and sterility of the genetic linkage is stable, 1990 ~ 1992 three years of plant height measured from jointing to heading stage, the height of the early and late, indicating that from the jointing stage, the plant height can be predicted Fertility. 1993 further validates the effect of early predictive fertility. Dwarf defeat offspring of offspring of offspring of male sterile and fertile plants will be isolated from the higher traits, but intra-plant segregation is still less than isolates, so in the way of future generations of planting, after a certain rotation generation, some sterile plants to plant lines, there Benefit to improve field selection efficiency. With Jinmai 2148 continuous backcross 4 times, the comprehensive characters of fertile plants were close to those of backcrossing parents, the plant height tended to be the same. The sterile plants except the plants were shorter, and other characters were similar to the male parent. , 0.8935,0.8501. on the basis of,?
