摘要
按照Griffing Ⅳ不完全双列杂交设计,利用11个相关农艺性状优良亲本筛选出55个杂交组合。所有F1代杂交组合及其亲本采用随机区组重复3次的方法,对番茄品质性状进行杂种优势研究与配合力分析,筛选出强优势与高配合力组合。结果表明,果形指数主要由加性效应组成,果肉厚度主要由显性效应组成,每个亲本不同性状的一般配合力(GCA)效应值均存在区别;硬度特殊配合力效应值最大组合为18P24×18696(70.23),果形指数特殊配合力效应值最高组合为18920×18P24(0.88),果肉厚度特殊配合力效应值最大杂交组合为18954×18943(1.05);综合3种品质性状最优越组合有:18920×18P24、18P24×18696、18954×18943;番茄各性状遗传力依次为果肉厚>硬度>果形指数。
According to the design of incomplete diallel cross of Griffing Ⅳ, 55 cross combinations were screened by using 11 excellent parents of related agronomic characters. All F1hybrid combinations and their parents used the method of random block repeat for three times to study the heterosis and analyze the combining ability of tomato quality traits, so as to screen out the combinations with strong heterosis and high combining ability. The results showed that the fruit shape index was mainly composed of additive effects, and the pulp thickness was mainly composed of dominant effects. The general combining ability(GCA) effect values of different characters of each parent were different. The combination with the largest hardness special combining force effect value was 18P24×18696(70.23),the combination with the highest special combining ability effect value of fruit shape index was 18920×18P24(0.88), the cross combination with the highest specific combining ability effect value of pulp thickness was 18954×18943(1.05). The most superior combinations of the three quality traits were 18920×18P24, 18P24×18696 and 18954×18943. The order of heritability of tomato characters was pulp thickness>firmness>fruit shape index.
