| 摘 要： | 对10个杂交种及对应的5个自交系的产量及植株形态性状进行了杂种优势的研究。结果表明,单株产量、保绿度、韧皮强度、根系拉力、叶面积系数等性状表现出很强的杂种优势,其中正向部分明显大于负向部分,且杂种优势指数高。叶向值的中亲优势和超亲优势多数属于负向部分。叶夹角的杂种优势较小,杂种优势指数都在100%左右。

| Abstract: | The experiment was carried out to study combining ability and genetic parameters of 10 hybrid and 5 inbred lines.The results showed that yield per plant,stay green degree,bast strength,root pulling force,leaf area index showed strong heterosis performance,in which the positive part was significantly greater than the negative part,and the hybrid vigor index was high.However,the mid-parent advantage and heterosis were mostly negative part for leaf of value.Plant leaf angle had less heterosis and heterosis indices were about 100%. |
