悬钩子种质评价标准

Rubus germplasm descriptor

九十年代初在南京建立了悬钩子属田间基因库。考虑到国内外尚未发表悬钩子属种质评价标准，特拟定此标准供田间基因库使用。内容包括登记数据、引种数据、栽植数据、繁殖保存数据、植株数据、病虫害敏感性、同工酶酶谱、染色体计数和备注等９部分。在植株数据中有：１．植株类型；２．植株大小；３．生长势；４．刺；５．萌蘖；６．顶端生根习性；７．枝蔓寿命；８．叶（包括叶成分等共１０项）；９．花序；１０．花；１１．果（包括果实成分等共１８项）；１２．适应性；１３．

The Rubus field gene bank was established in the beginning of 1990′s in Nanjing. As there was not yet any descriptor of raspberries and blackberries published, a descriptor of Rubus species was drafted here. There are 9 parts included: accesion, introduction, planting, propagation and preservation, plant, susceptibility to diseases and insects, isoenzyme electrophoretogram, chromosome number and comments. In the part of plant data, there are 13 items contained: 1. plant type, 2. plant size, 3. growth potential, 4. spine, 5. sprout, 6. tip rooting, 7. cane longivity, 8. leaf (totally 10 points including leaf analysis), 9. inflorescens, 10. flower, 11. aggregate fruit (totally 18 points including fruit analysis), 12. adaptability, 13. yield.
