遗传性状

There were close relation and harmonies among the quantities characters that were significantly hereditarily correlated with tumorous stem yield. High yield breeding combining with strong ecological adaptability and good quality should be largely based on later maturity, tumorous stem diameter, whole plant weight and higher ratio of stem and leaf.

瘤茎产量与营养生长期、瘤茎膨大期、瘤茎横径、茎/叶、株鲜重呈极显著遗传正相关，与菜形指数、菜皮百分率呈极显著遗传负相关，与其余性状相关均未达显著水平；与瘤茎产量显著相关的性状间关系密切，有很好的协同性，分析提出茎瘤芥育种选择熟性晚、瘤茎横径大、茎/叶高和植株个体较大的品种，可实现品种产量高、生态适应性强和瘤茎品质较佳等三者的协调统一。

Tumorous stem yield was only significantly hereditarily positively correlated with vegetative duration, developmental duration, ratio of stem and leaf, horizontal length and whole plant fresh weight, negatively fur percentage and tumorous stem index. There were close relation and harmonies among the quantities characters that were significantly hereditarily correlated with tumorous stem yield. High yield breeding combining with strong ecological adaptability and good quality should be largely based on later maturity, tumorous stem diameter, whole plant weight and higher ratio of stem and leaf.

结合油桃育种实践，对亲本、杂交后代的果皮茸毛、肉色、花粉育性、果实风味等性状进行了系统遗传分析，结果进一步证实了果皮茸毛、肉色、花粉育性3个性状各由1对等位基因控制，其中果皮有茸毛对无茸毛、白肉对黄肉、花粉可育对败育均呈完全显性，且这3对等位基因分别呈独立遗传，无互作效应；选择甜风味的品种作亲本，杂交后代出现甜油桃单株的比例较高。

Four male sterile lines and nine restorer lines were used in incomplete diallel crosses to analyze the genetic effects of appearance quality traits in japonica hybrid rice by using the genetic model and analysis method for quality traits of endosperms in cereal crops.
