近几年试验结果初步看出,花培再生植株是纯合二倍体,植株性状在各世代绝大多数是一致的。但是,在H_2—H_3亦出现极个别株系和单株的变异,H_3株系变异率为9.99％,单株变异率为0.3％,甚至在H_4个别材料和单株仍出现变异。变异范围广,变异类型多、有株高、穗型、粒型、芒型、粒色、抗病性和抗逆性等性状变异。 Preliminary results in recent years showed that the regenerated plants are homozygous diploid, plant traits in most generations is consistent. However, in H_2-H_3, there were also very few individual and single plant variation. The variation rate of H_3 was 9.99% and the variation rate of single plant was 0.3%. Variation of a wide range of types of variation, with plant height, panicle type, grain type, grain type, grain color, disease resistance and resistance traits and other traits variation.
