葡萄砧木新品种——华佳8号的选育

A New Variety of Grape Rootstock—Huajia No.8

利用华东葡萄(Vitispseudoreticulata)与佳利酿(Carignane)杂交,从其后代中选出了一个生长势极强的单株,其根系发达,扦插育苗成活率为45% ～55.8% 。作为砧木与藤稔等葡萄品种嫁接亲和力强,试验表明,华佳8 号与藤稔这一砧穗组合的幼树生长势极强,总生长量是常规巨峰砧藤稔的3.7 倍,有明显的乔化作用。5 年累计亩产量是巨峰砧的1.5 倍,果穗与果实品质均超过巨峰砧。笔者认为华佳8 号是藤稔葡萄较为理想的砧木品种。

Huajia No.8 grape rootstock was selected from hybrids (Huadongputao(Vitis pseudoreticulata)×Carignane(V.vitis)).It grows vigorously and has extuaordinarily strong root system,the rate of surviving plants by cuttings ranges from 45%to 55.8%.The compatibility with grape cultivars such as Fujiminori is perfect.The results of rootstock comparative tests showedthat the young vine of ‘Fujiminori’ grape grafted on Huajia No.8 rootstock grew vigorously;The total shoot growth length was 3.7 times compared with that grafted on‘Kyoho’;The accumulative yield of five years was 1.5 times as high as that grafted on ‘Kyoho’;The qualities of fruit and cluster were better than that on ‘Kyoho’.The authors consider that ‘Huajia No.8’ws suitable rootstock for ‘Fujiminori’ grape.
