摘　　要：试验以光山县4个长山核桃品种为研究对象,以波尼为母本进行人工授粉,通过测试花粉活力和坐果率初步筛选长势优良的品种。研究表明:花粉活力方面波尼>YLJ6>YLJ35>YLJ1,坐果率YLJ6>YLJ35>YLJ1。通过比较,最适宜本地栽植的杂交品种为YLJ6,YLJ1不适合在本地栽植。In This experiment,four Carya cathayensis varieties in Guangshan County were taken as the research objects,and Boni was used as the female parent for artificial pollination.By testing pollen vigor and fruit setting rate,the varieties with excellent growth were preliminarily screened.The results showed that in terms of pollen vigor,Bonny>YLJ6>YLJ35>YLJ1,and fruit setting rate YLJ6>YLJ35>YLJ1.Through comparison,the most suitable hybrid variety for local planting is YLJ6,and YLJ1 is not suitable for local planting.
