通过苗期枯萎病抗性鉴定及嫁接后甜瓜各项生理指标对比,发现砧木新品种雪金龙对当地甜瓜枯萎病致病菌——尖镰孢菌甜瓜专化型生理小种2号表现高抗,且嫁接后植株生长健壮,较商丘当地5个常用砧木品种嫁接苗增产显著。连续的田间试验及跟踪调查,进一步证实了雪金龙对枯萎病具备相对稳定的抗性,适宜推广。 Through the identification of fusarium wilt resistance in seedling stage and comparison of the physiological indexes of melon after grafting, we found that the new rootstock new species Xueyong Long showed high resistance to Fusarium oxysporum f. , And the plants after grafting robust growth, compared with the local Shangqiu five common rootstock varieties grafted seedlings yield significant. Continuous field trials and follow-up investigations further confirmed that the golden dragon has relatively stable resistance to blight and is suitable for promotion.
