郧西是鄂西北的一个山区县,历来盛产油桐(一九七九年270万斤)。在长期栽培管理过程中,油桐经过天然杂交和人工选育,形成许多地方性的优良品种。考察研究这些品种和品种系列的不同性状,用所长,其弃短,对培育新的良种及推动当前油桐生产发展,是不可缺少的重要一环。一九七八年春,我们在进行全县油桐品种资源调查时,从中发现一种丰产型的优良品种,经初步鉴定,该品种产油量高,抗逆性强,遗传性状比较稳定,主产在景阳公社
Yunxi is a mountainous county in northwestern Hubei and has always been rich in tung oil (2.7 million jin in 1979). In the long-term cultivation and management process, tung tree through natural hybridization and artificial breeding, the formation of many local varieties. It is an indispensable and important part to examine different traits of these breeds and breeds series, to use their strengths, to abandon them short and to cultivate new breeds and to promote the current development of Tonggu production. In the spring of 1978, when we conducted a survey on the resources of Tung oil varieties in the county, we found a good variety with high yield. After preliminary identification, the variety has high oil yield, strong resistance and relatively stable genetic traits. Production in Jingyang commune
