摘要:
以板栗为母本、锥栗为父本,进行种间杂交,对杂交产生的种实性状进行变异分析。结果表明:板栗和锥栗杂交后,其座果率降低,成熟期较父本锥栗有所提前;杂交栗苞形状偏向中性,栗苞质量、每苞坚果数显著高于锥栗,偏向母本,而苞刺长度、硬度及密度受父本影响较大;杂交坚果大小、质量显著大于父、母本,其中,两个杂交组合坚果质量分别为父、母本的1.81倍、1.23倍以上,坚果形状偏向母本,而坚果颜色、色泽受父本影响较大;聚类分析结果显示杂交种实栗苞、坚果性状与母本较为接近,而与父本相距较远。
Abstract:
Controlled cross was conducted on Castanea millissima as female parent and C. henryi as male parent in Qingyuan, Zhejiang province from 2008 to 2012. Analysis on variation of traits of hybrid nuts demonstrated that nut set rate was lower than normal pollinated one, and nut mature stage of hybrid was earlier than that of the male parent. Shape of hybrid cupule was neutral, and its quality, nuts per cupule was significantly higher than that of C. henryi, while the length, pubescence and density of spinelike bracts was greatly influenced by male parent. Size and quality of hybrid nuts was significantly greater than that of the male and female parent. Nut shape of hybrid was more like female parent, but color and luster like male parent. Cluster analysis showed that the traits of cupule and nut of hybrid was near to the female parent, but far apart from the male parent
