摘要: 【目的】 对初选的黑莓杂交品系进行综合评价,为进一步选育黑莓优良新品种提供科学依据。【方法】 对5个黑莓杂交品系(5-8-2、6-6-3、7-7-4、7-10-2、7-10-6)及其杂交亲本品种(‘Hull’、‘Chester’、‘Triple Crown’、‘Arapaho’、‘Kiowa’)的生物学性状(果熟期、刺的有无、叶色、植株生长量)和经济学性状(果穗数量、果实大小、果实品质、产量)进行调查与统计,采用层次分析法(AHP)进行综合评价,得到各指标对黑莓杂交品系的综合评价值和等级排名。【结果】 产量和果实品质是黑莓优良品种综合评价的核心指标。黑莓杂交品系6-6-3综合评价等级为Ⅰ级,5-8-2和‘Kiowa’为Ⅱ级,7-7-4、7-10-6、‘Hull’、‘Chester’、‘Triple Crown’和‘Arapaho’为Ⅲ级,7-10-2为Ⅳ级,其中5-8-2和6-6-3品系在南京地区生长、结果表现优良。【结论】 6-6-3和5-8-2品系综合评价值高,具有超亲优势,可作为候选优良新品种进一步观察研究; 7-7-4和7-10-6品系优点不明显; 7-10-2品系综合表现差,可在品种选育中淘汰。

Abstract: 【Objective】This study was performed in order to provide scientific data for blackberry breeding by a comprehensive evaluation of hybrid strains. 【Methods】 For the five blackberry hybrid strains(5-8-2, 6-6-3, 7-7-4, 7-10-2 and 7-10-6)and their parental cultivars(‘Hull’, ‘Chester’, ‘Triple Crown’, ‘Arapaho’ and ‘Kiowa’), the biological characters(fruit ripening period, thorn trait, SPAD value and growth trait)and economic characters(fruit cluster number, fruit weight, fruit quality and yield)were overall investigated and statistically analyzed, and the comprehensive evaluation value and rank were determined by the analytic hierarchy process(AHP)method. 【Results】Fruit yield and quality were decided as core indicators by comprehensive evaluation for blackberry breeding. The comprehensive evaluation rank of hybrid strain 6-6-3 was class Ⅰ, strain 5-8-2 and cultivar ‘Kiowa’ were class Ⅱ, strains 7-7-4, 7-10-6 and cultivars ‘Hull’, ‘Chester’, ‘Triple Crown’, ‘Arapaho’ were class Ⅲ, strain 7-10-2 was calculated as class Ⅳ. Strain 6-6-3 and 5-8-2 showed outstanding performance of growth and fruiting in Nanjing. 【Conclusion】 Strains 5-8-2 and 6-6-3 are promising candidate of new excellent blackberry cultivar because of their high comprehensive evaluation value and heterobeltiosis, the strains 7-7-4 and 7-10-6 are not clear, strain 7-10-2 should be eliminated in subsequent breeding program due to its low evaluation value.
