中华猕猴桃若干株系的染色体数目

CHROMOSOME NUMBERS OF SEVERAL STRAINS OF ACTINIDIA CHINENSIS VAR. CHINENSIS

摘要: 报道了中华猕猴桃10个株系的染色体数目。所有株系均为2n=116,为四倍体。植物体被软毛,平均果重71～100g,果实形状圆形、椭圆形、扁圆形或圆锥形。原产地海拔560～1035m。

Abstract: Ten large fruit strains of Actinidia chinensis var.chinensis were found to be tetraploid.Mean fruit weights are from 71 g to 100 g.Fruit shapes are spheroidal .ovoid, ellipsoid,or turbinate.Habitat altitutes are from 560 m to 1035 m.The relationship between fruit size and polyploidy as well as the genetic breeding value of the tetraploidstrains were discussed.
