湖北省山桐子野生种质主要经济性状分析评价

通过调查分析湖北不同分布区山桐子野生种质资源情况，比较其生长、果实、产量、含油率等通过调查分析湖北不同分布区山桐子野生种质资源情况，比较其生长、果实、产量、含油率等主要经济性状，发现湖北山桐子野生资源变异丰富；利用主成分分析法对所有野生种质资源进行综合评价，发现鄂西南地区山桐子表现优良，经济潜力巨大，其它地区山桐子含油率相比鄂西南地区具有一定优势，因此可通过人工杂交，将优势性状聚合，开发扩大山桐子利用潜力，提高山桐子经济价值，促进山桐子作为木本油料健康快速发展。

Analysis and Evaluation of Main Economic Characters of Wild Germplasm of Idesia polycarpa in Hubei Province

Abstract: Through investigating and analyzing the wild germplasm resources of Idesia polycarpa in different distribution areas in Hubei, comparing its growth, fruit, yield, oil content and other main economic characteristics, it was found that the wild resources of I. polycarpa were rich in variation. Using principal Through investigating and analyzing the wild germplasm resources of Idesia polycarpa in different distribution areas in Hubei, comparing its growth, fruit, yield, oil content and other main economic characteristics, it was found that the wild resources of I. polycarpa were rich in variation. Using principal component analysis to analyze all wild species, it was found that the I. polycarpa in southwestern Hubei had excellent performance and great economic potential.The oil content of I. polycarpa in other areas had certain advantages compared with the southwest part of Hubei. Therefore, artificial hybridization could be used to aggregate the dominant traits to develop and expand the use of I. polycarpa, improve the economic value of I. polycarpa in Bureau and promote the healthy and rapid development of I. polycarpa as a woody oil.
