摘要
以9个辣椒接穗品种和3个辣椒砧木品种为试材,采用苗期盆栽鉴测法,评价了不同辣椒品种及不同辣椒砧木对辣椒疫病的抗性效果。结果表明:供试辣椒品种中"BLD"、"DYQQ""PRMND"3个品种对辣椒疫病表现高抗,"DNP56"和"BT33"2个品种表现中抗,"科星六号"、"豫园新16-A"、"新机遇"、"绿冠"4个品种表现高感;供试的3个砧木"RS1"、"RS2"和"RS3"与接穗品种"新机遇"之间亲和力比较好,3个嫁接苗的成活率分别达到86.6%、83.3%和87.6%,3种砧木嫁接苗在苗期和移栽后的生育指标与接穗品种的自根苗没有显著差异,同时3种砧木嫁接苗均对辣椒疫病表现中抗以上抗性。
Taking nine pepper varieties and three pepper rootstocks varieties as materials,the resistance identification to phytophthora blight and the grafting effect of three rootstocks varieties were tested on pot culture.The results indicated that ＇DLD＇,＇DYQQ＇ and ＇PRMND＇ showed high resistance to phytophthora blight,and ＇DNP56＇ and ＇BT33＇ showed middle resistance,while ＇Kexing No.6＇,＇Yuyuanxin 16-A＇,＇Xinjiyu＇ and ＇Lvguan＇ showed high sensitivity to phytophthora blight.Three tested rootstock varieties were compatibility with scion variety ＇Xinjiyu＇.The survival rate of three rootstock varieties ＇RS1＇,＇RS2＇ and ＇RS3＇ reached 86.3%,83.3% and 87.6% respectively.There was no significant difference between growth indicators of three rootstock varieties and scion variety ＇Xinjiyu＇ which in seeding stage and after transplanting.At the same time,three varieties of rootstock grafting were detected to be at least middle resistance to phytophthora blight of pepper.
