摘要: 对138份来源于3个水稻与旱稻杂交的F1组合的花培材料进行水、旱栽培处理,筛选出抗旱、丰产的粳稻种质资源,并进行籼粳性分析、抗旱性鉴定。结果表明,双亲之一为抗旱型品种,其花培后代有50%左右的抗旱型植株;大部分花培后代的抗旱性呈连续分布,个别株系表现双向超亲分离,抗旱性状受微效多基因控制。在N培养来源于3个组合的花培植株多数表现为粳型,少数偏籼型。最后还对水稻抗旱性鉴定指标进行了讨论。

Abstract: 138 plants of F1anther culture for 3 crosses derived from "paddy rice/dry field rice"were treated under the condition of water and land culture in this study,respectively,japonica rice germplasm resource screened according to drought tolerance and high yield,meanwhile,indica-japonica type anlyzed and drought tolerance identified for these progenies,these results indicated one of bi-parents showed drought tolerance,about 50 percent progeny plants from anther culture was "drought tolerance type".The drought tolerance of most progeny plants was continuous distributed,individual progeny plant show bidirectional segregation beyond parents for drought tolerance,it was controlled by micr-multiple gene.Most plants from 3 combinings showed rice japonica type on N6 culture media,less indica type.Finally,Index of rice drought tolerance identification was being discussed.

Key words: Japonica rice, Anther culture, Germplasm resource, Drought tolerance
