摘要
龙眼葡萄是我国古老的优良鲜食、酿酒兼用品种,据1975—1985年对河北省张家口等老产区的普查,对变异株的定点观察和比较试验,发现该品种株间在产量、结果枝率、穗重等性状方面出现明显的分离。 初选22个混合系较普通系3年平均增产15.3％,而复选4个混合系又较初选混合系3年平均增产13.6％,并发现了白龙眼、深红龙眼、花皮龙眼3个色泽芽变系;大圆龙眼、鸡心龙眼、长龙眼3个果形芽变系和结果枝率极低及果穗松散的2个极低产类型。
'Long Yan' ( Vitis vinifera L. ) , an old grape variety native to China, is an excellent table- and wien-grape variety. Many bud muta-tions from 'Long Yan' grapevine were discovered following the general survey in some old grape-growing areas of Zhangjiakou in Hebei pro-vince in 1975-1935.
There were significant differences in yield-related characters, such as yield, percentage of fruiting cane,fruit cluster weight, etc. By com-paring these bud mutations with the original variety, the average yield of 22 primarily selected clones for 3 years increasced by 15.3%。 The average yield of 4 reselected clones increased by 13.6% than the primarily selected clones. From these clones, the following strains were selected: 'Bai Long Yan', 'Shen Hong Long Yan', and 'Hua Pi Long Yan', bud sports of fruit skin color、 'Da Yuan Long Yan', 'Ji Xin Long Yan' and'Chang Long Yan', bud sports of berry shape, Two types of very low yield were found, one with very low percentage of fruit cane and another with loose fruit clusters.
