| 摘要: |
| 罗汉果近交后代发生明显衰退,花和果变小甚至畸形,种子活力降低,品种间衰退速度不同; 杂交F1后代果实形状、大小、颜色、总苷含量、甜苷Ⅴ含量和雌花柱头生长方式产生严重分离变异,其中果实大小、总苷含量、甜苷Ⅴ含量表现出明显杂种优势; 雄性败育系的花粉败育是由遗传决定的,其败育性可通过杂交传递给雌性系产生无籽果实; F17芽变枝条所得雌雄同花两性突变属于遗传变异。 |

| Abstract: |
| Inbreeding of Siraitia grosvenorii could lead to depression of its progeny plants, their flowers and fruits became smaller or malformed, seed activity would decrease. Depression speed was different for varieties. Fruit shape,size,color,total mogrosides content,mogrosides Ⅴcontent and female stigma growth mode greatly separated among F1 hybrid progenies. Fruit size,total mogrosides content and mogrosides Ⅴcontent occurred heterosis. Pollen abortion of male abortive lines was determined by gene. Female plants could inherit the abortive character by cross and its fruits were seedless. Amphoteric mation of monoclinous flower branch were belonged to genetic variation. |
