| 摘 要： | 以6个糯玉米自交系为试材,采用Griffing方法(4)完全双列杂交,研究鲜食糯玉米株高、穗位高、地上第一节茎粗、地上第一节茎长、生育期、穗重、穗长、穗粗等8个性状的一般配合力、特殊配合力.结果表明:除地上第一节茎长外,其余各性状一般配合力差异均极显著;除穗粗及地上第一节茎长差异显著外,其余各性状的特殊配合力差异均极显著;穗粗主要受加性基因决定,其余性状同时存在加性基因效应和非加性基因效应.在多数性状上,一般配合力表现较高的自交系有P2、P6、P3和P5;特殊配合力表现较高的组合有P36、P15、P12、P16、P23和P26.

| Abstract: | Six inbred lines in glutinous corn were used as test materials and a complete diallele cross was carried out by the the Griffing method(4) in order to study the general combining ability(GCA),specific combining ability(SCA) of plant height,ear height,the first stalk diameter on ground,the first stalk length on ground,growth date,ear weight,ear length and ear diameter in fresh glutinous corn.The results showed that the difference among GCA of other traits was very significant except the first stalk length on... |
