多倍体育种是获得优质大粒葡萄新品种的重要途径之一。目前葡萄栽培品种多为二倍体(2n=2x=38),只有少数品种为四倍体(2n=4x=76),这些多倍体品种几乎都是通过芽变或杂交选育而成,使葡萄的多倍体育种受到一定的局限。据报道,
Polyploid breeding is one of the important ways to obtain new varieties of high quality grapes. At present, most of the grape cultivars are diploid (2n = 2x = 38). Only a few varieties are tetraploids (2n = 4x = 76). These polyploid varieties are mostly selected by budding or cross breeding. So that the polyploidy grapes are subject to certain limitations. According to reports,
