中华猕猴桃雄性株系“磨山4号”的选育研究

A NEW MALE SELECTION OF ACTINIDIA CHINENSIS──MOSHAN NO.4

通过对近年来选育的“磨山４号”、“磨山５号”、“武植８２－１２”、“武植８０－４”、“武植８２－５”等５个中华猕猴桃（ＡｃｔｉｎｉｄｉａｃｈｉｎｅｎｓｉｓＰｌａｎｃｈ）雄性株系的花期、花量、花粉生活力、花粉量的观察，并分析与“武植３号”授粉对果实的影响，从综合性状来看，“磨山４号”花期比一般雄株长２个星期左右（约２０天），有效花粉量高，株型紧凑，授粉后的果实单果重及Ｖｃ的含量均高于其它雄株，为中华猕猴桃适配雄株。

Five pollenizers selected in recent years,'Moshan No.4' 'Moshan No.5' 'wuzhi 82-12','wuzhi 80-4','wuzhi 82-5',were observed on the florescence,flower and pollen quantity, pollen viability and the effect on the fruit of pistillate 'Wuzhi No.3',The result showed that 'Moshan No.4' is a suitable pollenizer for A.chinensis according to its comprehensive characters that include:florescence lasts about 20 days,which is 2 weeks longer than other ordinary male vines:Each flower carries more vlable pollens,and the fruits from its pollination get higher mean weight and contain more vitamin C.
