籽用西瓜种质的苗期枯萎病抗性鉴定

摘要

Artificial inoculation of 62 inbreds derived from egusi watermelon, edible seed watermelon and regular watermelonrnto test their resistance to Fusarium wilt. Variation of resistance was observed in the test. Nineteen lines showed intermediaternresistance,42 lines showed low level resistance and 1 line was susceptible. High level resistance was not found among thernmaterials tested.%通过室内苗期枯萎病人工接种鉴定,对62份来源于籽用西瓜、黏籽西瓜及普通西瓜杂交后代自交纯系进行枯萎病抗性鉴定,显示出不同自交系之间抗病性的差异,供试材料中鉴定出19份中抗、42份轻抗和1份感病材料,没有发现免疫和高抗材料.
