连续3年以北方板栗品种“燕山红栗”和“燕龙”为父本,以南方板栗品种“云富”、“云良”、“云早”、“永丰1号”为母本进行授粉,测定了不同授粉组合板栗的结苞率、空苞率、出籽率、球苞直径和坚果重量等指标,以期为改善板栗坚果品质和提高产量提供参考。结果表明:不同授粉组合对板栗结苞率、空苞率的影响较小;球苞的大小与母本的自身特性以及球苞内坚果个数相关;利用坚果大的品种花粉授粉比利用坚果小的品种花粉授粉所结的坚果要大,且坚果的大小也与球苞内坚果的个数相关。
For 3 years in a row, the northern chestnut varieties “Yanshan Hongli ” and “Yanlong ” were used as the male parents and the southern chestnut varieties “Yunfu ”, “Yunliang ”Yongfeng 1 " was pollination for the female parent, and the indexes such as the rate of tuberous bud, the rate of empty panicle, the seed yield, the diameter of the bulb and the nut weight were determined in order to improve the quality and increase of chestnut nut Yield for reference. The results showed that the effect of different pollination combinations on the rate of bolls and the rate of empty shell was small. The size of the ball bales was related to the female parent’s own characteristics and the number of nuts in the ball bract. Using large nut varieties, The varieties of pollinated nuts to be large, and the size of the nuts are also related to the number of the ball bracts nuts.
