Nut Settings and Nuts Traits of Interspecific Hybridization between Juglans sigillata and Jregia
To analyze nut setting rate,nut dropping rate and other characters of 8 hybrid combinations,two famous varieties of Juglans sigillata (J.sigillata cv.'Yangpao',J.sigillata cv.'Santai')and two excellent varieties of J.regia (J.regia cv.'Chandler',J.regia cv.'Hartley')were selected as pollinators at the walnut garden of Kunming Arboretum in 2015.The results showed that the nut setting rate and dropping rate of different combinations were quite different.The nut setting rate varied from 2 % to 67%,and the coefficient of variation was 107%.The nut dropping rate varied from 33% to 98%,and the coefficient of variation was 33%.The average nut weight,seed size and carved lines of F1 hybrids were similar to that of female parent,and this indicateding that the nut characters of walnut fruit were mainly controlled by female parent and not influenced by male parent pollen.It was proved that the selection of pollinator with strong affinity and high nut setting rate could significantly increase the yield of walnut and had no effect on its nut character.
