以油茶上级雄性不育无性系为试材，对其产量性状、遗传性状、开花特性及花粉生物学特性进行了研究，结果表明：油茶花粉粒多皱缩不规则形，花粉发育不全或不饱满，影响其萌发力，不育系的花粉外壁比上级无性系的厚，说明山茶属不育系并非完全不育，利用RAPD分子标记技术对“MS”系统进行分析，发现“MS”系统的许多遗传性状与普通油茶有显著差异，但与上级无性系1、3、12有密切的亲缘关系。
A superior male-sterile clone of Camellia oleifera was taken as tested material,its yield traits,genetic character,flowering and pollenbiological characteristics were studied.The results show that pollen grains have more shrinkage irregular shape and was a hypoplasia or less full of pollen,those affected its germination power,pollen exine of male-sterile line was thickness than the superior clone's.The results also indicate that male-sterile clone of Camellia was not entirely non-sterile,but its pollen activity was far lower than the normal fertile pollen fine clone's.By using RAPD molecular markers,it was found that many genetic traits of "MS" system were siginificantly different from common Camellia oleifera trees but had close relationship with superior clones 1,3,12.
