| 摘 要： | 选用Lemont、CPSLO17、02428、明恢63、培矮64、IR36等6个蛋白质含量高低不同的材料作亲本配制杂交组合，进行籽粒蛋白质含量的分析。结果显示F2及回交世代分离大、变异广，有部分植株超过了高值亲本，因此，可从F2或回交世代就进行单株选择。双亲蛋白质含量对后代有影响，但母本作用更大。建议选配组合时以高含量作母本为宜，若要进行回交选育，宜用高含量的母本作轮回亲本。

| Abstract: | P1, P2,F1,F2,B1,B2 in five combinations were used as materials and the genetic variability of grain protein content were analyzed. The results show protein content in rice grain belongs to quantitative traits controlled by polygene, F, and backcross generations present approximately normal distribution in continuous variation. There are some plants whose protein content of grain are higher than parents with high content among segregating generations. Selection was undertaken beginning with low generations, it is probable to obtain fine individuals. Parents' protein content affects progenies, whereas the female parents have much bigger effect. It is beneficial to use parents with high protein content as female parents in breeding combinations. |
