Evaluation and Selection of Newly Selected Superior Southern-type Black Poplar Clones for Cultivation in Jianghan Plain
To screen suitable new superior southern-type black poplar clones for cultivation in the Jianghan Plain and accelerate the renewal of improved poplar varieties in the region, this study used the currently dominant elite cultivars ‘Danhong Yang’ and ‘Nanlin 895’ as controls. Twelve black poplar clones selected through early screening were evaluated. Through the 8-year positioning test from 2017 to 2024, the growth indexes such as diameter at breast height (DBH), plant height and volume of different forest ages were measured. Combined with the stem straightness, variance analysis, genetic parameter estimation and selection index method were used to evaluate the excellent clones. The results showed that extremely significant differences (P<0.01) existed in DBH and tree height among the 14 tested clones (including controls) at all ages. Volume at 8 years also showed highly significant differences, the individual tree volume of maximum clone at 8 years was 3.87 times that of the minimum clone. Growth rates for DBH and height varied significantly among clones over the 8-year period. Some clones exhibited faster growth in the first 2 years, others accelerated between years 3-4, and some showed rapid growth primarily from years 5-8. Net increment data for DBH, height, and volume at different ages revealed distinct growth patterns for southern-type black poplar in the Jianghan Plain. Fast-growth period occurred from 1 to 4 years post-planting for DBH, fast-growth period peaked between years 3-4 for height, fast-growth period spanned years 3-6 for volume. The repeatability of DBH, plant height and 8-year-old volume were 0.85-0.92, 0.89-0.92 and 0.88, respectively, which were all high repeatability traits. Based on growth indicators (at 8 years) and stem straightness, three clones (‘HB-3650’, ‘08-01-52’ and ‘08-01-41’) outperforming the control ‘Danhong Yang’ were selected from the 12 tested clones, representing a selection ratio of 25%. This study provides high-quality materials for the regeneration of poplar varieties in Jianghan Plain. In the future, comprehensive trait evaluation can be further carried out in combination with stress resistance, wood quality and other traits to accelerate the popularization and application of excellent clones.

为筛选出适合在江汉平原推广的杨树优良无性系，以引进的‘丹红杨’等19 个杨树无性系及江汉平原原主栽品种‘中潜3号’为材料，分别分析林龄6年和12年时20个无性系的生长量、材性及抗性。林龄6 年和12 年杨树各无性系胸径、树高、单株材积均存在极显著差异，其中‘丹红杨’、‘巨霸261’、‘DD102-4’、‘南林895’、‘巨霸2025’等5 个无性系表现突出，12 年材积分别高出对照107.7%、50.18%、39.8%、50.9%、42.1%；5 个无性系在基本密度、纤维长度方面存在显著或极显著差异；‘丹红杨’、‘鲁山杨’抗病虫性最强。结合材积生长节律分析，认为‘丹红杨’适合培育中小及大径材，‘巨霸261’适合培育大径材，其他3个无性系适合培育中小径材。
