【摘要】 为了弄清产油量与鄂油无性系各性状因子间的关系,对10个鄂油无性系的20个主要性状因子与产油量之间的关系进行了灰色关联度分析。结果表明:不同性状因子与单株产油量的关联度不同,关联度较大的前5个性状因子分别是鲜果出仁率、冠幅、含油率、出籽率和油酸含量。这一结果表明,在鄂油无性系良种选育过程中,应重视对油茶鲜果出仁率、冠幅、干仁含油率等主要性状因子的研究。更多还原

【Abstract】 In order to learn relation of oil yield and the character factors of Eyou clones,grey correlation degree of 20 main characters and oil yield of 10 Eyou Clones were analyzed.The results show that different characters have different correlation degrees with oil yield.The five characters with higher correlation degrees are kernel rate of fresh fruit,crown,oil rate of dry kernel,seed ratio of fresh fruit,oleic acid content.So the main character factors should be thought highly during breeding improved varieties,for example,kernel rate of fresh fruit,crown,oil rate of dry kernel and so on.更多还原
