一、前言山核桃(Carya cathayensis Sarg.)具有结果早、种仁味佳等特点,其缺点是果小、壳厚;而薄壳山核桃(Carya pecan Engler.et Graebn.)果大、含油量高(一般比山核桃高17.3％)、壳薄、壳与种仁易于剝离,但结果较迟、抗病虫力弱。因此我们期望通过有性杂交和定向培育,以创造出兼具两个亲本优良性状的山核桃或薄壳山核桃的新品种、

I. Introduction Carya cathayensis Sarg. Has the characteristics of early fruiting and tasty kernels, and has the disadvantages of small fruit and thick shell; and the fruit of Carya pecan Engler.et Graebn. Is large in oil content High (generally 17.3% higher than pecan), thin shell, shell and seed easily peel, but the results later, the resistance to pests and weaker. Therefore, we hope that through sexual cross-breeding and directional cultivation, we will create a new variety of pecan or pecan that has both parents’ excellent traits,
