清水县引进核桃品种基本性状初步对比试验

通过对近年来引进清水县的香玲、西林2号等7个早实核桃品种及晋龙1号、晋龙2号等2个晚实核桃品种的树体、枝条性状和果实经济性状等的调查,并以清水当地优良品系清水薄皮核桃为对照。结果表明：早实核桃香玲、鲁光和辽核7号在清水县综合表现良好;中林1号产量较高,但种仁不饱满,且容易感染炭疽病;辽核4号产量高,但果实较小,且大小年明显。

Based on survey of tree body,branches properties and fruit economic characters of 7 introduced early bearing varieties of walnut such as Xiangling,Xiling 2 etc.,and 2 late bearing varieties of walnut such as Jinlong 1,Jinlong 2 etc.of Qingshui county in recent years,native fine variety thin shelled walnut in Qingshui county as control.The results showed: comprehensive performance of early bearing varieties of walnut such as Xiangling,Luguang and liaohe 7 in Qingshui county was good;yield of Zhongling 1 was higher,but seed kernel was not plumpness and it was easy to infect anthrax;yield of Liaohe 4 was high,but the fruit is smaller and major or minor year was obvious.
