油桐杂交育种的目的是使它能更有效地产生符合人类经济利益的新基因组合,育成新品种。关于油桐杂交育种工作,前人已做了很多试验研究,积累了经验,取得了一定的成效。1969年四川省林科所在16个品种中进行了111个组合的品种间杂交,从 F_1代中选出了2个杂种优株;经过11年的观察,这2个杂种植株在生长速度、丰产性、抗病性等方面均发现了很
The purpose of the tung hybrid breeding is to make it more efficient to produce new gene combinations that are in line with the economic interests of mankind and to breed new varieties. About tung tree hybrid breeding work, predecessors have done a lot of experimental research, accumulated experience, and achieved some success. In 1969, 111 hybrid combinations were made among 16 cultivars in Linchu of Sichuan Province, and 2 hybrid superior plants were selected from F 1 generation. After 11 years of observation, these two hybrid plants showed significant differences in growth rate, High yield, disease resistance and other aspects are found very
