试验结果表明:西瓜果实可溶性固形物含量,一般配合力和特殊配合力均较高的B_2(SO4自交系)、B_4(石红2号自交系)是提高西瓜甜度育种较为理想的亲本。在十五个杂交组合中,B_2(SO4自交系)×B_6(兴城红自交系)F_1,B_3(富研自交系)×B_4(石红2号自交系)F_1特殊配合力最高,是提高果实甜度较为理想的杂交组合。
The results showed that B_2 (SO4 inbred line) and B_4 (Shihong No.2 inbred line), which had higher soluble solid content, higher general combining ability and higher specific combining ability, were the ideal parents to improve watermelon sweetness breeding . Among fifteen hybrid combinations, B_2 (SO4 inbred lines) × B_6 (Xingcheng red inbred lines) F_1, B_3 (Fuyan inbred lines) × B_4 (Shihong 2 inbred lines) F_1 special combining ability The highest, is to improve the sweetness of fruit hybrid ideal combination.
