Yield and traits of nut,and nutrients of kernel under different hazelnut cultivars
[Objective]To select the high-yielding and high-quality varieties suitable for cultivation based on nut yield and traits of different hazelnut varieties in Jilin province.[Method]Three hybrid hazelnut varieties were chosen to analysis nut characteristics based on hazelnut yield,nut traits,and nutrients of kernel.[Result]The nut yield per plant in Dawei and Liaozhen 7 was 43.6% and 39.6% higher than that in Liaozhen 3(P＜0.05).The calcium content of kernel in Dawei was 18.4% and 16.1% higher than that in Liaozhen 7 and Liaozhen 3,respectively.The total sugar content of kernel in Dawei was 9.9% higher than that in Liaozzhen 3.The unsaturated fatty acid content of kernel in Liaozhen 3 was 26.7% higher than that in Liaozhen 7.The protein content of kernel in Dawei was 13.8% lower than that in Liaozhen 7.The carotene content of kernel in Dawei was 1.82 times higher than those in Liaozhen 3.There were significant differences in the vitamin E content among the three varieties with the highest occurred in Liaozhen 3 showing 23.4% and 66.5% higher than Dawei and Liaozhen 7,respectively(P＜0.05).The average diameter of nut in Dawei was larger than Liaozhen 7,but smaller than Liaozhen 3.The kernel mass and ratio in Liaozhen 3 with the thinnest shell were higher than the other two varieties(P＜0.05).Liaozhen 7 showed the highest sphericity and lowest shape index,followed by Dawei.Random forest regression models and principal component analysis showed that the vitamin E content of kernels and the longitudinal diameter of nuts were the most important nutritional and morphological factors response to hazelnut varieties(P＜0.05).There were positively correlated between shell mass and kernel mass with hazelnut mass(R2=0.85,0.56),and the slope in shell mass was more than twice that of the kernel.The average diameter of hazelnuts was positively correlated with hazelnut mass,kernel mass,and shell mass(R2=0.47,0.43,0.35).[Conclusion]Dawei shows the highest yield and kernel per plant,with a nearly spherical shape conducive to shelling,and higher unsaturated fatty acids,protein,vitamin E content,and the highest total sugar,carotene,and calcium content.Therefore,Dawei is relatively suitable for hazelnut cultivation in the Jilin region.
