貴州泡核桃育種目標及策略探討

打開文本圖片集

摘要：針對貴州泡核桃的性狀、種質(zhì)資源和育種現(xiàn)狀，分析了貴州泡核桃的育種目標。認為抗性強、相對晚開花，早結(jié)，頂枝和側(cè)枝都能結(jié)果的品種是貴州泡核桃當前育種目標。主要的育種策略是引進早實種質(zhì)及加強豐產(chǎn)優(yōu)質(zhì)種質(zhì)資源的利用。

AbstractAccording to the characters，germplasm resources and breeding status of Juglans sigillata Dode in Guizhou，the breeding objectives of Juglans sigillata Dode were analyzed.It was considered that the varieties with strong resistance，relatively late flowering，early fruiting and fruiting on top and side branches were the main breeding objectives of Juglans sigillata Dode at present.The main breeding strategy was to introduce early bearing germplasm and strengthen the utilization of highyield and highquality germplasm resources.
