黑美人类型西瓜新品种比较试验研究

Study on Comparative Test of New Heimeiren Watermelon Cultivars

[目的]筛选综合性状优良的西瓜新品种。[方法]2009年在海南黑美人类型西瓜新品种比较试验中,对引进和征集的32个品种的生物学特性、产量、品质、抗病性、抗逆性和综合性状进行比较和评价。[结果]根据各品种的综合表现,从中筛选出表现较好的新品种5个,即,KSU-428、KSU-431、早熟西瓜9号、小黑子和黑翡翠,其植株生长势中等,抗逆性和抗病性较强,果实商品率高,口感风味佳,丰产性表现突出,综合表现较优,推荐其参加西瓜品种生产试验,并可以适当面积推广。美丰、屯丰大果美人、红与黑、绿宝06、绿宝07、华联大果黑美人、兴农黑美人、新大美人、农之子大果黑美人等15个品种表现也较好,推荐其继续参加黑美人类型西瓜新品种比较试验。[结论]该研究为黑美人类型西瓜新品种推广提供依据。

[Objective]The study aimed to screen the new watermelon cultivars with the superior comprehensive characters.[Method]In the Heimeiren watermelon cultivar comparison test in Hainan Province in 2009,the biologic characters,yield,quality,disease resistance,stress resistance and comprehensive characters of 32 introduced and collected cultivars were compared and evaluated.[Result]According to the comprehensive performance of 32 cultivars,5 watermelon cultivars with better performance were screened,which were KSU-428,KSU-431,Zaoshuxigua 9,Xiaoheizi and Heifeicui.They had middle plant growth vigor,stronger stress resistance and disease resistance,high fruit commodity rate,good taste and flavor,outstanding yielding ability and superior comprehensive performance,so they were recommend to attend the watermelon cultivar production test and could be popularized in appropriate area.The 15 watermelon cultivars such as Meifeng,Tunfengdaguomeiren,Hongyuhei,Lvbao 06,Lvbao 07,Hualiandaguoheimeiren,Xingnongheimeiren,Xindameiren and Nongzhizidaguoheimeiren also had better performance and they were recommend to continually attend the Heimeiren watermelon cultivar comparison test.[Conclusion]The study provided the basis on the popularization of new Heimeiren watermelon cultivars.
