摘要
[目的]选育高抗梨黑星病的优良品种和品系.[方法]对自主选育的26个品种和品系进行梨黑星病抗性鉴定和主要经济性状的测定.[结果]经过2～5年的连续性鉴定,供试品种和品系均表现为高抗,抗病性状极其稳定,都具备较高的经济价值,符合优质高产高效的育种目标.[结论]这些品种和品系经过区域试验之后完全可以作为抗病优质新品种在生产上推广应用,抗病优质新品种的应用对于减少农药施用、降低成本、提高产出、减少环境污染等都具有重要的意义.
Abstract
[Objective] Excellent varieties and series with highly resistance to pear scab were bred.[Method] The resistance to pear scab and several economics traits of 26 pear varieties and series had been evaluated for 2-5 years.[Result]26 pear varieties and series were high resistant to pear scab,the disease resistance was extremely stable.All the pear varieties and series had good economic value,which were conformed to the breeding goals.[Conclusion] All pear cultivars and series could be popularized and applied in production as resistant and high quality varieties after area test,which was very significant for reducing cost of production,reducing pesticide application,increasing farmers' income and reducing environment pollution.
