摘要
为了丰富我国早实核桃品种资源及选育仁色浅、商品性状好的优良品种,于1985年从引进的新疆核桃种子实生苗中选育出了一个早实核桃新品种——晋香(原代号为"晋6032"),随后对其树体的生长特性及结果习性进行了系统调查、抗逆性测定和区域栽植试验。结果表明:其树姿较开张,雄先性,为中熟品种;坚果壳面光滑美观,平均单果质量为11.5g,壳厚0.75mm,出仁率63.97%,易取整仁,浅色仁的比例占96%,仁饱满,风味特香,品质上等;盛果期的果枝率为85.5%,果枝的坐果数为1.4个;单位树冠垂直投影面积产仁量0.18～0.20kg·m-2。该品种适宜矮化密植或乔化栽培。
In order to enrich the variety resources of early fruiting walnut in China and select excellent breed with pale kernel and good commercial characters,a new variety,Jinxiang walnut（original code：Jin 6032）,was introduced from seedlings of Xinjiang walnut in 1985.Growth and fruiting habits were systematically investigated,and resistance and regional planting trials were carried out.The results showed that its average nut mass was 11.5g,and shell with thickness of 0.75mm was smooth;kernel was easy to be wholly extracted out,kernel percentage was 63.97%,and light kernel percentage accounted to 96%.Fruit shoot rate was 85.5%,and there were 1.4fruits in a fruit shoot. Kernel yield of canopy vertical projective area was 0.18-0.20kg·m-2.Tree vigor was medium upright.Jinxiang walnut was a protandrous and mid-maturation variety,and it was fit of dwarfing and close planting or arbor form cultivation.
