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 。
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 F_(1) 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.
