通过多年自然病圃播种和盆栽试验,测定了桃的不同种和类型对根结线虫的抗性。结果表明:不同种和同一种不同类型间的差异很大,寿星桃(红花重瓣)、甘肃桃(红根)、垂枝桃是很好的抗性材料;山桃、部分光核桃和部分毛桃等亦是有希望的抗性材料;贝蕾、寿星桃中的白花单瓣和粉花单瓣以及其它几个种和类型的抗性很差。
Through years of natural nursery sowing and pot experiments, the peach species and types of root knot nematode resistance was measured. The results showed that there were great differences between different species and the same type. The species of Shou Xing (safflower), Gansu peach (red root) and weeping peach were very good resistant materials. Peaches and the like are also promising resistant materials; the resistance of the white flowers and the single flowers of the flowers and the several other species and types in Beilei and Longevity peaches is poor.
