桑树远缘杂交F1代植物学性状的表现分析
Botanical Characters Expression of Distant Hybrid F1 in Mulberry
【摘要】 对桑树 1 4个亲本的 8个远缘杂交组合进行调查分析表明 ,F1 代叶、枝条、冬芽等的植物学性状大多数倾向亲本 ,但性状分离强烈 ,表现出亲本没有的丰富的植物学特征。F1 代的农艺性状综合表现趋势为 :野生桑 (♀ )×栽培种 (♂ )类型绝大多数都表现出明显的野生性状 ;栽培种 (♀ )×野生桑 (♂ )类型部分组合F1 代与野生桑 (♀ )×栽培种 (♂ )类型的F1 代近似 ,部分组合的F1 代倾向栽培种。因此 ,野生桑与栽培种远缘杂交应以栽培种 (♀ )×野生桑 (♂ )类型为主 ,并特别注意选择好远缘杂交的母本
【Abstract】 The botanical characters such as leaf, branch and winter-bud mostly trend to their parents with wide segregation and some new characters by investigating eight distant hybrid combinations from fourteen mulberry parents. The comprehensive (expression) of F1 agronomical characters obvious by trend to wild characters in most (wild mulberry ♀×cultivated mulberry ♂) combinations and partial (cultivated mulberry ♀×wild mulberry ♂) combinations. The cultivated mulberry(♀)×wild mulberry (♂) should be the main combination form in distant hybrid of mulberry.
