1981年以来,在开展对刺梨种质资源的调查和选种工作中,选出优株剪枝扦插或挖取植株定植于选种圃内,观察生长结果情况,并采果分析其品质差异。扩大栽培面积后,再从中选出优株繁殖,建立良种母本园。现将可供生产应用的优良株系简介如下: 贵农1号母株原产于兴义县顶效区鲁屯乡,于1981年杨胜学、樊卫国等在资源调查中发现。剪枝扦插繁殖的后代,树高1.5米左右,冠径2.5米左右,树冠极开张,枝披垂,树装强,枝粗长,徒长性的结果母枝长1.5米左右。较丰产,株产5公斤左右。果实长仿锤形,顶部较小,基部狭长高突,皮刺较软,果色鲜黄艳丽,外观美,果较大,单果平均重18克左右,最大果重23.2克(原产地29.1克),果肉厚0.65厘米,纤维少,单宁含量低,汁较多,肉
Since 1981, in carrying out the investigation and selection of Rosa roxburghii Germplasm resources, we selected the best cuttings pruning or digging plants planted in the selection of nurseries to observe the growth of the results and picking fruit analysis of its quality difference . Expand the cultivation area, then select the superior strains breeding, the establishment of seed mother garden. Now available for production and application of excellent strains are as follows: Guinong 1 parent strain native to Xingyi County Dingding District Lutun Township, in 1981 Yangsheng Xue, Fan Weiguo found in the resource survey. Pruning cutting propagation of offspring, the tree height of 1.5 meters, about 2.5 meters in crown diameter, the crown is very open, hanging branches drape, tree strong, thick branches long, only the result of leg length of 1.5M. More abundant, producing about 5 kilograms. The fruit has a long, quasi-hammer-like shape with a small top and a narrow base. The prickles are softer and the fruit is bright yellow with beautiful appearance. The average fruit weight is about 18 grams and the maximum fruit weight is 23.2 grams (29.1 grams ), Flesh thickness 0.65 cm, less fiber, low tannin content, more juice, meat
