摘要： 利用网纹甜瓜和哈密瓜类型材料杂交,经6～7代系谱选择,选育出了3个网纹甜瓜新品系,并对其稳定性、抗病性和配合力进行了综合评价。结果表明:品系1、品系2表现出高度的一致性和遗传稳定性;品系1对白粉病呈HR抗性,品系2呈R抗性,品系3呈MR抗性;品系1和品系3单果重的一般配合力效应呈正向效应(GCA值分别为0.02和0.09),品系2的网纹一般配合力高(GCA值为0.16),品系3的单果重、果肉厚、糖含量均呈正向效应。

Abstract: Stability, disease resis tance and combining abil ity are evaluated compr ehensive after was selectived 3 new net ted melon strains crossed with Muskmelon andHami melon types by 6 ～ 7 eras.It indicates that the characters of s train 1 and 2 are homogeneity and hereditary stability; strain 1 is high resistant to powdery mildew, strain 2 is res istant.General combining abil ity of per fruit weight for strain 1, 3 are posit ive(GCA =0.02, 0.09).Combining abil ity of netted trait is high for strain 2(GCA=0.16)and per fruit weight, fruit thickness, sugar contant for s train 3 posit ive too.
