摘要
连续2a观察海南省昌江县海尾镇双塘村18龄实生腰果园中的41份种质植株,测定记录株高,冠幅,坚果产量,坚果、果梨大小及重量比,坚果出仁率,果仁质量等级等,并进行综合比较。结果表明,18份种质的经济性状均优良,可进一步开展种质比较试验,筛选出更优良的高产、稳产、矮化和耐寒的腰果新品系。
Forty-one accessions of cashew germplasm were observed in successive two years, and they were eighteen years old in Changjiang County, Hainan Province. Some agronomic and economic properties of these germplasm were mensurated and registered, such as tree height, tree spread, nut yield, size and ratio of nut and apple, kernel percentage of nut, grade of whole kernel, etc. Results showed that 18 accessions of germplasm had desirable economic properties and deserved further comparison trial for selection of better new cashew clones with high and stable yield, dwarfing and cold resistance.
