摘要
2006—2008年,在四川省板栗重点产区开展乡土板栗优良种质资源的选择工作。按坚果品质、外观和单株丰产性等板栗优树选择的主要指标,进行优树的初选、复选和决选。通过实地调查并参照板栗国家标准(GB 10475—89)、板栗丰产林国家标准(GB/T 9982—1988)及部分地方标准制定四川省板栗优树选择标准,经多性状综合评定,最终筛选出8份优良种质材料。
Taking nut quality, appearance, yield per plant as the key indicators for plus trees, the preliminary selection, semifinal selection and the final selection of superior native chestnut germplasm resources were carried out in the major chestnut production areas of Sichuan Province from 2006 to 2008. Having referred to the National Chestnut Standards （GB10475--89）, National Standards for High Yield Chestnut Plantation （GB/T 9982--1988） and some local standards, the selection criteria for chestnut plus trees in Sichuan Province were formulated based on the field surveys. Finally, 8 individual superior germplasm materials were screened out by comprehensive assessments with the multiple traits.
