摘要：

为明确云瑞甘蔗创新种质与目前常用亲本资源间的遗传差异并筛选优异新种质提供育种利用。本研究以61份由国内外品种(系)组成的甘蔗常用亲本和54份云瑞创新种质2种类型的资源为材料, 利用荧光SSR标记进行遗传多样性、亲缘关系和群体结构分析, 同时对云瑞创新种质进行新植和宿根农艺性状调查, 并利用DTOPSIS法进行综合评价。结果表明, 66对SSR标记在甘蔗常用亲本资源和云瑞创新种质中分别检测到368个和355个位点, 基因多样性指数分别为0.6746和0.6773, 多态性信息含量(PIC)均值分别为0.6179和0.6201, 表明甘蔗常用亲本和云瑞创新种质均具有丰富的遗传多样性。基于UPGMA聚类的亲缘关系分析将115份参试材料划分为5个类群, 其中, 云瑞创新种质与常用亲本资源被划分在不同类群, 与群体结构和主坐标分析结果基本一致, 表明云瑞创新种质与目前常用亲本资源在遗传组成上具有异质性。DTOPSIS分析鉴定出23份综合性状优良的云瑞创新种质, 其在产量和糖分相关性状上表现良好, 可作为高产、高糖亲本利用。本研究利用SSR标记揭示了云瑞创新种质与目前常用亲本资源的遗传差异, 同时用DTOPSIS法评估了其育种利用潜力和价值, 为甘蔗育种提供了新亲本, 丰富了甘蔗遗传基础。

Abstract:

To clarify the genetic differences between the Yunrui series innovative germplasm and commonly used sugarcane parental resources, and to identify elite new germplasm for sugarcane breeding, two types of materials were analyzed: 61 commonly used sugarcane parents, including both domestic and international varieties (lines), and 54 accessions of Yunrui innovative germplasm. Genetic diversity, genetic relationships, and population structure were evaluated using fluorescent SSR markers. Additionally, agronomic traits of the Yunrui germplasms were assessed in both plant cane and ratoon cane, and comprehensively evaluated using the DTOPSIS method. The results showed that 66 pairs of SSR primers detected 368 and 355 loci in the commonly used parents and Yunrui germplasm, respectively. The gene diversity indices were 0.6746 and 0.6773, and the average polymorphism information content (PIC) values were 0.6179 and 0.6201, indicating high genetic diversity in both groups. UPGMA clustering classified the 115 accessions into five groups, clearly distinguishing the Yunrui germplasm from the commonly used parents. These findings were supported by population structure and principal coordinate analyses, confirming genetic differentiation between the Yunrui germplasm and current parental lines. The DTOPSIS analysis identified 23 Yunrui accessions with superior comprehensive traits. These accessions exhibited promising yield and sugar-related characteristics, suggesting their potential as parents for breeding high-yielding, high-sugar content varieties. This study not only revealed the genetic differentiation between Yunrui innovative germplasm and commonly used parents based on SSR markers, but also demonstrated their breeding potential through comprehensive trait evaluation using the DTOPSIS method. The findings provide valuable parental resources for sugarcane breeding and contribute to broadening the crop’s genetic base.

Key words: sugarcane, fluorescent SSR, genetic diversity, genetic relationship, DTOPSIS method, breeding potential
