摘要/Abstract

摘要： 金坪矮垂栗是从普通实生板栗中选出的变异类型, 其自交后代出现直立和垂枝性状的分离近
似3∶1, 直立性与垂枝性呈显、隐性基因关系。金坪矮垂栗自然授粉有性后代矮化性仍有保存, 可利用其
作为栗的矮化育种材料。嫁接结果表明, 以金坪矮垂栗实生苗为砧嫁接良种板栗, 可实现板栗的矮化密植
与丰产栽培。

Abstract: Castanea mollissima var. pendula is a special variety with dwarfing and pendent branches,
was selected from the seedlings of Castanea mollissima in Jinping, Jiangxi. There were the erect p lants and the
pendent p lants in the selfed p rogenies of Castanea mollissima var. pendula and the isolated ratio is 3∶1. The
erect characterwas dominated by dominant gene and pendent characterwas dominated by recessive gene. The
sexual progenies of C. mollissima var. pendula were still dwarfing. C. mollissima var. pendula could be uti
lized dwarfing breeding of C. mollisima. The grafted results showed that C. mollissima var. pendula will be utilized for the dwarfing and a good yield of C. mollissima.

Key words: Castanea mollissima, Sexual progenies, Dwarfing, Pendent
