摘要
亚籼粳稻杂交能较好地克服籼粳杂交所不易克服的缺点,比较容易选育出高产更高产的品种。在选材上两亲本中必须有一籼粳杂交的后代,具有籼稻血缘,另一亲本必须具有耐寒基因。在选育过程中,应严格淘汰基因型早衰的材料。
Hybridization between O.sativa subsp.shien and O.sativa subsp.
keng is an easier way than that from O.sativa shien and O.sativa
keng to overcome some of hybrid deficiencies better and to create ever
high yield varieties.In breeding material selections,one of their par-
ents must be the descendant with O.sativa shien blood.While the
other with cold-resistant gene.Those materials that show early sene-
scence should be completely eliminated through breeding.
