Abstract
[Objective] Gummy stem bIight <GSB> is an important disease in meIons. Identification of germpIasm and breeding of meIon resistance to GSB are the most effective way to controI GSB disease in the fieId. [Method]In this study, l40 meIon Iandraces in Xinjiang Region were screened for resistance to GSB by the way of inocuIation on seedIings. [ Result] After the first investigation of resistance to GSB, 53 Iandraces incIuding ' Huangdanzi ' were resistant to GSB on Ieaf symptom, and aII Iandraces except ' HongrouakeIawati ' were highIy resistant to stem symptom. After the second investigation, aII Iandraces were susceptibIe to GSB but 5 Iandraces except ' Oiuhuangpi bairou kekouGi ' were toIerant to Ieaf symptom, and 6 Iandraces incIuding ' Oiuhuangpi bairou kekouqi ' were resistant to stem symptom. Resistant symptom on Ieaf and stem of meIon was positiveIy correIated, and correIation coefficient was 0. 88.[ Iconclusion] Resistant symptom on Ieaf to GSB was dispIayed earIier and more heaviIy than that on stem* but there was notabIe significance in reIationship between symptom on Ieaf and stem to GSB. ' Oiuhuangpi bairou kekouGi' was highIy resistant to GSB, and ' KaIakesai ' , ' Paotaihong' , ' Hami jiageda' , ' Tacheng dongtiangua' and ' BaiIangua ' were resistant to GSB.关键词
