摘要:

在田间自然感病条件下,对临海杨梅种质资源圃的112个杨梅种质资源凋萎病发生情况进行调查,并进行相关抗病性研究,以期为杨梅资源的合理利用和凋萎病的抗性育种提供参考。结果表明,112个杨梅种质资源对凋萎病均表现为不同程度的感病,其中29个杨梅种质表现高抗和抗病,占被调查种质的25.89%。杨梅属毛杨梅、蜡杨梅、矮杨梅和杨梅4个不同种间对凋萎病的抗性存在明显差异,其中,毛杨梅抗性较强,表现为高抗和抗病;杨梅种抗性次之,高抗、抗病占该种总数的25.23%;蜡杨梅耐病与中感各占50%;矮杨梅抗性最弱,表现高感。杨梅雌雄株对凋萎病的感病性也存在差异,雄株抗性表现整体优于雌株。

Abstract:

To provide references for the utilization and resistance breeding of Myrica resources, 112 Myrica germplasm resources in Linhai were used for studying their resistance to twig blight disease by natural infection in field condition. The results showed that 112 Myrica germplasm resources were susceptible to twig blight disease in different degrees, among which, 29 showed high resistance and resistance, accounting for 25.89%. The resistance of Myrica germplasm resources to twig blight disease was significantly different among the four species. Myrica esculenta species showed high resistance and resistance to twig blight disease, followed by Myrica rubra species, which had 25.23% germplasms of high resistance and resistance. Myrica cerifera species had 50% tolerant and 50% moderate susceptible germplasms, respectively. And the resistance of Myrica nana species was the weakest, showing high sensitivity. The susceptibility of male and female Myrica plants to twig blight disease was also different, the resistance of male plants was better than that of female plants.

Key words: Myrica, germplasm resources, field, twig blight disease, resistance evaluation
