| 摘 要： | 用3个野生甜菜——大果甜菜、叉根甜菜和滨海甜菜与糖甜菜进行种间杂交,有5个组合得到了杂交种,获得率为3.5%～14.3%。杂种F2产生分离,野生甜菜作母本糖甜菜为父本的杂交组合,表现为非孟德尔式分离,并持续到F4以后。杂交后代选出的优良变异系号随着选择代数的增加而更加优化。从叉根甜菜和滨海甜菜杂种后代分离出新的细胞质雄性不育系。糖甜菜作母本野生甜菜为父本的杂交组合,F2为孟德尔式分离,可得到一定数量优势强抗病系号,但随着繁殖代数的增加一些系号的优势逐渐降低。

| Abstract: | Five cross combinations by three wild beets,Beta macrocarpa Guss.,Beta patula Ait.,Beta maritima L.and sugarbeet got the hybrids,the cross rate were 3.5%-14.3%.Segregation happened on F2 generation,the combination which wild beet used as female and sugarbeet used as male represented non Mendelian separation law till F4 generation.The fine variation lines selected from cross offspring appeared better than that of its last generation.The novel cytoplasmic male-sterile lines were isolated from offspring of cross combination of Beta patula Ait.and Beta maritima L.The combination which sugarbeet used as female and wild beet used as male represented Mendelian separation law,some excellent resistance to disease lines,but some lines seemed to appeared worse than that of its last generation. |
