俗有“千花一果”之称的文冠果,由于类群复杂,良莠不齐,单位面积种子产量一直较低,影响了生产的发展。我所从1980年至1986年间,从省内选出的20株优树中,筛选出7 株丰产性状稳定,遗传增益大,单位面积种子产量高的优树,并通过了国家级鉴定。这几株优树,定植后4—6年,平均亩产种子达108.39公斤,是普通文冠果的4.68倍;种子出仁率可比普通树提高10.57％;种仁含油率可比普通村提高4.01％;每亩产油量达37.09公斤,是普通树的5.38倍。其中辽005号优树亩产种子达163.25公斤,是普通树的7倍;每亩产油量56.1公斤,相当于215公斤大豆的出油量,是普通树的8倍。
Popular with “a flower a fruit,” said the text of the crown, due to complex groups, good and bad, per unit area of seed production has been low, affecting the development of production. From 1980 to 1986, we selected 7 excellent trees selected from the province and selected 7 excellent trees with high yield traits, high genetic gain and high seed yield per unit area, and passed the national appraisal. These several excellent trees, 4-6 years after planting, the average per mu yield of seeds up to 108.39 kilograms, 4.68 times the common paper crown; seed kernel rate increased 10.57% than ordinary trees; seeds of oil than the average increase of 4.01 %; Oil yield per acre up to 37.09 kg, 5.38 times the normal tree. One of Liaoyu 005 acres of seed trees per mu reached 163.25 kilograms, seven times the ordinary tree; yield 56.1 kilograms per mu, equivalent to 215 kilograms of soybean oil, is 8 times the ordinary tree.
