摘要

根据海曼法对南瓜品质和产量贡献性状进行了5 × 5双列分析。以南瓜5个高级自交系IB 23、IB 40、IB 47、IB 50和IB 57为材料。选用5个亲本及其f1杂交种，采用随机完全区组设计，每3个重复，研究对品质和产量有贡献的性状。方差分析表明，除干物质和果实产量外，其余性状基因型间差异均显著。亲本均数表明所有亲本均含有正效隐性等位基因。在5 × 5双列组合中，除果长、干物质、糖度和还原糖存在非等位基因互作外，其余性状均存在等位基因互作。农业学家2016;14 (1) 15-32

Diallel Analysis of Quality and Yield Contributing Traits of Pumpkin ( Cucurbita moschata Duch. ex Poir.)

A 5 X 5 diallel analysis was carried out according to Hayman on quality and yield contributing traits of pumpkin. Five (5) advanced inbreds of pumpkin viz IB 23, IB 40, IB 47, IB 50 and IB 57 were used in this study. The five parents and their F 1 hybrids were arranged in a randomized complete block design with three replications for studying the quality and yield contributing traits. Analysis of variance showed significant differences among genotypes for all of the traits except dry matter and fruit yield. Parental mean suggested that all the parents contained recessive alleles with positive effect. In the 5 × 5 diallel set, Wr-Vr graph analysis revealed the presence of allelic interaction in all the character’s except fruit length, dry matter, brix percentage and reducing sugar where non-allelic interaction was present.
