摘　　要：四倍体少籽西瓜杂交新组合403×B15是2007年秋利用中小果型优良高世代四倍体自交系B15作父本,中果型四倍体西瓜403作母本,进行杂交配组筛选出的四倍体新组合,一般单果重3.0~3.5 kg,果实正圆形,表皮深绿有光泽,布有隐暗花纹,皮质坚韧,皮厚1.0~1.2 cm,果肉鲜红色,汁多,清甜爽口,剖面光滑,纤维黄筋少,中心可溶性固形物含量11.2%以上;中熟品种,全生育期春造90~100 d,秋造65~80 d。2009~2010年,连续2年进行露地爬地、大棚立架栽培品比试验和多点生产栽培示范试验。结果表明,露地爬地品比试验平均产量分别为31 775.9和34 377.2 kg/hm2,分别比对照黑美人增产14.2%和21.3%;大棚立架栽培品比试验平均产量分别为50 274.0和47 401.2 kg/hm2,分别比对照黑美人增产22.3%和15.8%;多点生产栽培示范试验平均产量32 124.0~48 499.5 kg/hm2,比对照品种黑美人增产14.0%~23.7%。该组合适宜露地爬地和大棚立架栽培。Tetraploid few seed watermelon hybrid combination 403×B15 was crossed by inbred B15 as male parent with tetraploid watermelon 403 as female parent.The fruit of combination 403×B15 were circular and 3.0-3.5 kg weight,with tough,green with glossy,ghost line and 1.0-1.2 cm depth skin,the fruit was fresh red,succulent,refreshing,smooth profile and less fiber,over 11.2 % soluble solids content.Combination 403×B15 was middle ripening variety with 90-100 d whole growth stage in spring cropping and 65-80 d in autumn cropping.The results of demonstration test in 2009 and 2010 showed that the average yield of combination 403×B15 were 31 775.9 and 34 377.2 kg/hm2 in open field experiment,which increased by 14.2 % and 21.3 %,respectively,compared to control variety Heimeiren.The average yield of combination 403×B15 were 50 274.0 and 47 401.2 kg/hm2,respectively,in 2009 and 2010,which increased by 22.3 % and 15.8 %,compared to control variety.Its average yield was 32 124.0-48 499.5 kg/hm2 in multi-site demonstration test,which was 14.0 %-23.7 % higher than control variety Heimeiren.It indicated that combination 403×B15 was suitable for planting both in open field and greenhouse.
