1、北京地区小果型西瓜品种筛选试验研究于琪摘要:为农户和市民提供更多、更优质的小果型西瓜品种,以及为北京地区新优小果型西瓜品种的进一步推广提供数据依据,笔者选用了近两年引进的新品种桂瓜3号、KM、九龙迷你、L-800、L-600,以京秀为对照,对产量、抗病性、果实品质等指标进行筛选研究。结果表明:6个品种在植株长势、抗病性、坐瓜率及商品瓜率各方面均处于较优水平。L-800的坐瓜节位最低为11节。折合产量桂瓜3号最高为5600.98Kg/667m2,与其他品种间呈显著性差异,其他品种与对照间差异不显著。产值方面九龙迷你、L-800、L-600高
2、于对照,分别为15653.67元/667m2、15583.05元/667m2和15488.87元/667m2。L-800、九龙迷你、L-600的边缘可溶性固形物比对照京秀高,L-800边缘可溶性固形物最大为12.07%,与其他品种间呈显著性差异。中心可溶性固形物九龙迷你最高为13.63%,与对照京秀、桂瓜3号和KM之间呈显著性差异。九龙迷你、L-800、L-600的口感酥脆多汁、纤维细、黄筋极少。从产量、效益和品质综合考虑,九龙迷你、L800与L600表现优良,推荐北京瓜农种植。关键词:北京地区;小果型西瓜;品种筛选IntheBeijin
