    The 3 salt tolerance varieties and 3 salt sensitivity varieties were used as parents to generate F1. F2 form a half diallel cross. It was employed to investigate the inheritance of salt tolerance by using Hayman's diallel cross analysis. The results suggested that the general combining ability (GCA) was highly significant difference between salt tolerance and salt sensitive varieties.
    根据Hayman的方法,对6个耐盐性不同的棉花品种(系)及其15个半双列杂交组合的F1、F2 代的平均盐害级别进行了双列杂交分析,结果表明,耐盐和盐敏感品种的一般配合力效应差异达极显 著水平,耐盐×盐敏感组合的特殊配合力普遍低于盐敏感×盐敏感、耐盐×耐盐组合。

the analysis of yieltls belween two lines from same parent and two sib-crosses showed no significant in sibcrosses (reciprocal cross ). as well as in sib -lines and between sib -cross and sib - line. the difference in yields was caused by the difference of tester. the results of combining ability analyses was showed that the general combining ability was no significant in the two lines、the two sib - crosses、 between line and sib - cross, but the GCA of testers was significant.

被测的两个同源自交系和相配的两个姊妹种.系与系之间、系与姊妹种之间、姊妹种之间(正反交)产量差异都不显著、而产量之间的差异主要是由于测验种之间的差异造成的。配合力测定结果.两个同源自交系和两个姊妹种中,系与系之间,系与姊妹种之间,两个姊妹种之间一般配合力差异不显著,说明利用配合力差异不显著的姊妹种替代自交系是可以作为杂交亲本生产种子的。

With 120 crosses made from 16X16 diallel cross, the relationship among parental expression,general combining ability (GCA),special combining ability (SCA) and heterosis were studied. The main results showed that the heterosis of various characters of 120 crosses was most significantly and positively correlated with the SCA. Some crosses had lower SCA, but still had high heterosis because the heterosis effect in GCA effect of these crosses was high. If the heterosis effect of both parents in GCA effect was low, though this cross had high SCA effect, it could not have high heterosis. The crosses with strong heterosis would be possible with both parents having high GCA and SCA effects.

利用16个小麦亲本及其双列杂交的120个F1为材料研究了亲本性状表现、一般配合力、特殊配合力及杂种优势间的关系,结果表明:各性状杂种优势与特殊配合力均存在极显著正相关;如果亲本一般配合力效应中含有较高的杂种优势效应,即使组合的特殊配合力较低,也有可能表现较强的杂种优势;若双亲一般配合力效应中杂种优势效应都较低,即使该组合特殊配合力较高,也难以表现明显的杂种优势。强优势组合选配应在亲本高一般配合力的基础上选择高特殊配合力组合。

The genetic significance of general combining ability(GCA)was analyzed and it was pointed out that the genetic essence of GCA was individual heretability.The effect of individual heretability used in crops' genetics and breeding was explained.

分析了一般配合力的遗传意义,提出一般配合力在实质上就是个体遗传力,并论述了个体遗传力在作物遗传育种中的应用。
