摘　　要：对南京 11,光壳稻和巴利拉或秋光配制的单交、测交 2 8个组合F1,F2 及其亲本在云南籼粳交错区的宜良县进行育性鉴定分析表明 :(1)云南光壳稻与籼粳杂种F1易受低温影响 ,其广亲和基因难以表达。南京 11与矮嘎、明子谷、木帮谷、毫秕、镰刀谷、末烈谷等光壳稻杂种F1和F2 代的育性表达基因不同 ,F1的育性表达基因易受环境影响 ;但F2 育性表达符合广亲和基因的遗传模式 ;并受主基因控制。 (2 )南京 11,光壳稻与巴利拉测交组合F1单株多数为不育株 ,不育株与可育半不育株比例符合X2 检验 1∶1理论值的分界以 5 %和 10 %居多。 (3)云南光壳稻与籼粳杂种育性基因的表达与环境因子密切相关 ,秋光的S -Cross combinations were made with Nanjing 11, Balilla or Akihikari and Nuda rice(with glossy, hairless husk) varieties and the fertility of their F 1s and F 2s was evaluated at Yiliang county of the cross areas of indica and japonica in Yunnan Province:(1) Hybrid F 1 between Yunnan nuda and indica or japonica was easily affected by the low temperature, its wide compability is difficult to express. It is difference to fertility expression gene of hybrid F 1 andF 2 between Nanjing 11 and Aiga,Mubanggu, Liandaogu and Moliegu etc.varieties, F 1 fertility expression is easily affected by environment, but F 2 conform to genetic model of the wide compability gene, and it is controlled by the mainly gene. (2) Most single plant of test cross F 1 between Nanjing 11, Balilla and Nuda rice are the sterile plants. The fertility boundary that the rate of the sterile and ferility plants (including semisterility plant) accorded with the theory value(1∶1) were relatively more at 5% and 10%.(3) It is connected with the environment to fertility expression gene of hybrids between Yunnan nuda rice and indica or japonica, S-8 fertility restoring gene of Akihikari and this gene belongs to allele.
