锥栗农家品种人工授粉杂交果实性状的变异分析
Variation analysis of crossing fruit traits obtained by artificial pollination of Castanea henryi local cultivars
摘要
Abstract
[Objective]The study aimed to screen excellent pollination and crossing combinations of Castanea henryi.[Method]The variation analysis of fruit traits was carried out by cross pollination with 5 fine varieties of Castanea henryi as experimental materials.[Results]The results showed that the largest variation range of fruit characters among 16 cross combinations was chestnut bud weight and nut weight,and the smallest was fruit type index.The traits such as involucre weight,nut weight,nut length,nut width and seed yield have positive correlation in varying degrees,which can be selected jointly.The traits of involucre weight,nut weight,chestnut bract length,chestnut bract width,chestnut bract height,and seed yield have different degree of pollen xenia effect.The fruit traits of each pollination combination with ZL1 as female parent and ZL12 as male parent were excellent,and five excellent pollination combinations were selected.The GCA effect of ZL1 and ZL12 is relatively high,while that of the crossing combination ZL1×ZL9,ZL6×ZL12,ZL3×ZL6 have the highest SCA effect.[Conclusion]The results can provide reference for cross breeding and high-yield cultivation.关键词
