Pollination configuration of Castanea mollissima cultivars in Luotian County
[Objective]This objective was to screen pollination combinations with high fruit yield and quality for Castanea mollissima(chestnut)cultivars in Luotian County,Hubei Province.[Method]Six chestnut cultivars cultivated in Luotian County,Hubei Province,were selected.Based on flowering period overlap,22 pollination combinations were designed and the pollination configuration experiments were carried out,fruiting after pollination and fruit characteristic were investigated and analyzed.[Result]Cross-pollination significantly decreased the empty bract rate(P＜0.05),except'Wukeli',each other cultivars'empty bract rate of cross-pollination was lower than that of self-pollination.Cross-pollination significantly increased the final fruit setting rate(P＜0.05),the final fruit setting rate of self-pollination was lower than 50％except for'Wukeli'.Pollination cultivars showed significant effect on bracts index,nuts index,kernel's protein and starch content(P＜0.05).Based comprehensively on final fruit rate,fruit characteristic indexes and principal component analysis,pollination combinations(♀ ×♂)with high fruit setting rate and good fruit quality were:'Guihuaxiang'×'Bayuehong','Bayuehong'×'Liuyuebao','Liuyuebao'×'Guihuaxiang','Liuyuebao'×'Bayuehong','Wukeli'×'Liuyuebao','Meiguihong'×'Qiancidabanli','Qiancidabanli'×'Guihuaxiang','Qiancidabanli'×'Wukeli'.[Conclusion]Proper pollination varieties configuration could efficiently decrease the fruit empty bract rate and promote the fruit yield and quality of chestnut cultivars in Luotian County,and the high yield and excellent quality production could be realized.[Ch,3 fig.5 tab.26 ref.]
