| 摘 要： | 云雄是云南省林业科学院经济林研究所历时20多年选育出的板栗新品种,通过优株选择、无性系评比试验、物候观测、授粉试验、花粉生活力测定、区域化栽培试验、产量和品质测定等多年的栽培研究.结果表明,该品种坚果大、品质优、产量高.用其授粉,平均成实率高达87.4％,且对主栽品种坚果增重明显,增重幅度为4.9％～26.3％.用云雄花粉人工辅助授粉,较自然授粉平均每公顷增产396.5 kg,增产率18.5％;坚果平均增重1.43 g,增长率16.4％.因此,在板栗栽培中,选用云雄作为授粉品种,对提高产量和品质具有重要作用.

| Abstract: | Yunxiong is a new chestnut cultivar which lasted more than 20 years breeding,it is selected based on the study of superior strains,clones rating test,phenological observations,pollination experiment,pollen viability determination,the regionalization cultivation test,yield and quality determination.This cultivar with larger size,good quality nut and higher yield,it’s not only can be used as main planting cultivars,but also has longer male inflorescence,long flowering period for pollination and higher fruiting rate(average 87.4 %),increase the fruit size and production(4.9 %~26.3 %),improve the quality of the nuts.The production yield can be increased average 396.5 kg per ha(about 18.5 % growth rate) and the average weight of nut is 1.43 g(16.4 %) by artificial pollination.As pollinated cultivars,Yunxiong plays an important role in chestnut cultivation. |
