优良品种是增产的物质基础。我国板栗良种选育工作,以往均系实生选优和品种提纯,而通过人工杂交方法育出的新品种或优系,至今尚未见有报道。 35号是在研究亲本遗传性状的基础上,选配性状各异的野板栗(父本)和红粟(母本)进行人工套袋杂交,从其实生后代中选择培育成的优良无性系。1973年杂交,1974 Good varieties are the material basis for increasing production. Breeding of chestnut breeding in our country, in the past are both real selection and purification of species, and artificial breeding by breeding new varieties or excellent lines, has not been reported. On the basis of studying the genetic traits of parents, No. 35 selects the elite male clones with the different traits and the red millet (female parent) to carry on the artificial bagging hybridization and selects the elite clones that are bred from their actual offspring.
