Abstract：
Breeding high yielding groundnut cultivars with 2-3 weeks of fresh seed dormancy, particularly in Spanish-type cultivars, enhances the sustainability of agriculture in groundnuts. In this context, we conducted a comprehensive phenotypic and genotypic evaluation of advanced breeding lines developed in the genetic background of Spanish types. By employing multi-phenotyping and marker data, we identified PBS 15044, 16004, 16013, 16015, 16016, 16017, 16020, 16021, 16026, 16031, 16035, 16037, 16038, 16039, 16041, and 16042 with 2-3 weeks dormancy (> 90%).The various parametric and non-parametric estimates identified the stable fresh dormant genotypes with one or more superior economic trait. PBS 16021, 15044, 16038, and 16039 identified with high hundred pod weight (HPW) were also reported having high intensity of dormancy (> 90% for up to 3 weeks); PBS 15044, 16016, PBS 16038 and PBS 16039 with high hundred kernel weight (HKW) also reported with up to 3 weeks fresh seed dormancy; and PBS 16013, 16031, and 16038 with up to 3 weeks fresh seed dormancy had high shelling percentage (SP). They can be used to develop lines with the desired level of dormancy, and high yields, by designing appropriate breeding strategies.
摘要：
培育2-3周新鲜种子休眠的高产花生品种，特别是在西班牙型品种中，提高花生农业的可持续性。在这种情况下，我们对在西班牙类型的遗传背景下开发的高级育种系进行了全面的表型和基因型评估。通过使用多表型和标记数据，我们鉴定了PBS15044,16004,16013,16015,16016,16017,16020,16021,16026,16031,16035,16037,16038,16039,16041和16042,休眠2-3周(>90%).各种参数和非参数估计确定了具有一种或多种优良经济性状的稳定的新鲜休眠基因型。据报道，鉴定为高百果重量（HPW）的PBS16021、15044、16038和16039也具有高强度的休眠（长达3周>90％）；PBS15044、16016，PBS16038和PBS16039的高百粒重量（HKW）也报告了长达3周的新鲜种子休眠；并且PBS16013、16031和16038的新鲜种子休眠百分比高达3周（SP）。它们可用于开发具有所需休眠水平的品系，和高产量，通过设计适当的育种策略。
