                摘要:
                為豐富和創新成縣核桃育種材料,改良現有核桃品質,以當地品種隴南15為母本,隴南755、香玲、薄豐、遼核2號、遼核3號等品種為父本,開展核桃雜交育種試驗,對F1代的開花與結果習性、果實表型性狀『等指標進行了觀察和測定,同時對就是與朱俊州憑身體硬擋也不是問題不同核桃雜交種F1代果實性狀多樣性進行了分析。結果表明:以早實性和雄先型的核桃為父本與隴南15雜交,可以獲得結實期提前和雌花開花期推遲的雜交甲殼種; 不同雜交組合,所得雜種後代果實表型性狀差異顯著(P<0.05),各雜種果實果殼表面特征整體表現較好; 不同雜交組合所得雜種F1代果實性狀存在多樣性,變異最大的是果殼厚度,其次是出仁率和單果重,果實大小差撞到了墻上異較小。
                Abstract:
                In order to enrich and innovate breeding materials of walnut in Chengxian and improve the quality of existing walnut varieties, the variety of Longnan 15 was used as the female parent, Longnan 755, Xiangling, Bofeng, Liaohe No.2 and Liaohe No3 were used as male parent for the cross breeding experiment of walnut. Flowering, fruiting performance and fruit phenotypic traits of F1 generation were observed and determined at the same time, the fruit character diversity of F1 generation of different walnut hybrids was analyzed. The result showed that the walnut with early-fruiting as the father to cross with Longnan 15 would have hybrid with fruiting early and male flowering late. Different hybrid combinations showed significant differences in the phenotypic traits of hybrid offspring(P<0.05). The surface characteristics of the fruit shells of each hybrid fruit performed well; the fruit traits of F1 generation of hybrid were different in different hybrid combinations. The largest variation was the shell thickness, followed by the yield and single fruit weight. The fruit size difference was small.
