国外黑萝卜种质资源的引种鉴定及评价

为筛选出适合杭州地区的萝卜育种材料，为后续萝卜育种工作做好铺垫，以本地品种一点红为对照，调查从国外引进的8份黑萝卜材料的植物学性状、商品性、产量等指标，对引进材料进行适应性研究和综合评价鉴定，确定其用途。结果表明，8份材料中391633的商品性、田间抗病性及产量均较突出，特别是其肉质根颜色深红，口感好，不易抽薹，可直接作为小型深色春萝卜品种的亲本，也可作为培育水果萝卜新品种的种质材料。

In order to screen out suitable radish breeding materials in Hangzhou area and preparing for following breeding, we took local cultivar Yidianhong as control, studied introduced materials' suitability, identified comprehensive evaluation and determined their use by investigating botanical characters, commodity, yield and other indexes of eight introduced foreign black radish materials. The results showed that, commodity, field resistance and yield of 391633 were outstanding. Especially, it had characters such as dark red fleshy root color, good taste, not easy to blotting. So, it could be directly used as small dark color spring radish cultivar's parent, and could be used germplasm material for cultivating new fruit radish cultivar.
