摘　　要：针对宁夏设施土壤连作障碍引起的番茄根结线虫问题,以引进的12个品种为试材,以"黄金606"为对照,研究了不同品种的植株长势、果实品质、土壤根结线虫密度以及根结指数。结果表明:"黄金606"根结线虫数量和根结指数最高,根结指数9级,田间抗病性差;"粉果307"始花节位较低,植株长势较好,加权灰关联度相对较高,且"粉果307"、"黄金929"土壤线虫数和根结指数较低,"粉果307"根结指数0级,"黄金929"植株长势较好,抗病性强,丰产性强,根结指数1级,因此"粉果307"和"黄金929"果实中等匀实,抗根结线虫强,植株长势好,可作为高产优质抗线番茄粉果品种进行推广。Aiming at the problem of root-knot nematode caused by continuous cropping obstacles in Ningxia,‘Gold 606＇was used,12 species that were introduced as materials,the different species of plant growth,fruit quality,root knot nematode density and root knot index were studied.The results showed that‘Gold 606＇root knot nematode density and root knot index was highest,whose root knot index was 9,and whose field resistance was poor.The node of the first flower of‘Pink tomato 307＇was lower,and plant growth was better,weighting gray correlation degree was higher.Soil nematodes density and root knot index of‘Pink tomato 307＇and‘Gold 929＇were low,‘Pink tomato 307＇knot index was 0.‘Gold 929＇plant growth,disease resistance,high yield were better and root knot index was 1.So the‘Pink tomato307＇and‘Gold 929＇fruit type were well,anti-knot nematode were strong,plant growth,were better,they could be as anti-knot nematode and high yield varieties for extention.
