“红船精神”是以“红船”为具体意象，对中国共产党先驱领袖身上所体现“建党精神”的生动描绘。“焦桐”作为体现焦裕禄精神的典型意象，生动体现了焦裕禄在艰苦条件下带领兰考群众同自然灾害作斗争、通过种植泡桐树将万亩盐碱地变成... 详细信息

“红船精神”是以“红船”为具体意象，对中国共产党先驱领袖身上所体现“建党精神”的生动描绘。“焦桐”作为体现焦裕禄精神的典型意象，生动体现了焦裕禄在艰苦条件下带领兰考群众同自然灾害作斗争、通过种植泡桐树将万亩盐碱地变成良田，造福一方百姓的不朽业绩与崇高风范。如果说“红船”“焦桐”是以静物、植物为标识符号进行中国共产党人精神谱系的意象书写，那么“三牛”精神则是以孺子牛、拓荒牛、老黄牛的动物符号作为中国共产党人崇高精神的物化象征。

Background: Gossypium arboreum is a diploid species cultivated in the Old World. It possesses favorable characters that are valuable for developing superior cotton ***: A set of 197 Gossypium arboreum accessions were genotyped using 80 genome-wide SSR markers to establish patterns of the genetic diversity and population structure. These accessions were collected from three major G. arboreum growing areas in China. A total of 255 alleles across 80 markers were identified in the genetic diversity ***: Three subgroups were found using the population structure analysis, corresponding to the Yangtze River Valley, North China, and Southwest China zones of *** growing areas in China. Average genetic distance and Polymorphic information content value of G. arboreum population were 0.34 and 0.47, respectively, indicating high genetic diversity in the G. arboreum germplasm pool. The Phylogenetic analysis results concurred with the subgroups identified by Structure analysis with a few exceptions. Variations among and within three groups were observed to be 13.61% and 86.39%, ***: The information regarding genetic diversity and population structure from this study is useful for genetic and genomic analysis and systematic utilization of economically important traits in G. arboreum.

【目的】通过1 500个陆地棉杂交组合分析杂种优势与其亲本间数量性状遗传距离的相关性,探讨能否利用大规模杂交组合亲本间遗传距离提高陆地棉杂种优势预测效果,以期为棉花杂交育种和杂种优势利用提供理论指导。【方法】选择来自15个国家和中国23个省(市)的305份陆地棉核心种质为亲本,采用L×T(Line×Tester)杂交设计配制1 500个杂交组合。2012—2013年,在中国南北方13个生态环境下考察其株高、单铃重、衣分、纤维长度等10个产量和纤维品质相关性状,分析F1杂种优势、亲本间遗传距离和群体结构,并采用4种方式(Cor1—Cor4)计算遗传距离与杂种优势的相关性。【结果】10个性状中亲优势(MPH)均值的变幅为1.70%—7.40%,平均为4.36%,按父本不同将F1分成5组(A—E),其MPH均值A>E>B>C>D;超亲优势(HB)均值的变幅为-4.17%—1.87%,平均为-0.17%,A、B和E组的HB均值皆为正。10个性状在5组中除D、E组的马克隆值之外,其他性状普遍具有明显的中亲优势,其中,单铃重和纤维长度的中亲优势在5组中均以正优势为主(达80%以上),最大值分别为34.01%和9.83%,对应的超亲优势分别为24.25%和5.80%。F1和亲本差异显著性分析表明单铃重、株高、纤维长度、伸长率和整齐度指数整体表现出一定的超亲优势。父本(测试种)与300个母本之间的遗传距离介于2.280—61.430,平均为21.550,5个测试种与母本间的平均遗传距离D>C>E>A>B,其中,最近值为11.721,最远值为33.271。按最小方差聚类,将305个陆地棉亲本划分为2个主群,包括5个亚群。4种遗传距离与杂种优势的相关性分析结果显示,因样本量、遗传距离变幅和父本不同其结果有所差异,相关性随样本量的增大而有所增强。其中,Cor1是Cor2结果的整体体现;Cor3与Cor1和Cor2相比,部分性状的中亲优势与遗传距离的相关性有所不同;Cor4的相关性最弱。综合来看,遗传距离与衣分、断裂比强度、整齐度指数和纺纱均匀性指数的中亲优势呈显著正相关,遗传距离与其他性状的中亲优势的相关性因采用的分析方案不同,结果有所不同;在4种方案中,除整齐度指数外,遗传距离与超亲优势的相关性整体表现负相关。其中,遗传距离与马克隆值、纤维长度和衣分的超亲优势相关性较强。【结论】陆地棉亲本间数量性状遗传距离与杂种优势有一定的线性关系,不同性状的杂种优势与遗传距离的相关性存在正负和强弱差异,且样本量越大相关性越强。说明基于大规模杂交组合研究陆地棉亲本间遗传距离与杂种优势的关系效果显著。
