Abstract

: Dolichos bean is grown in environments with short and long crop growth seasons. Development and deployment of cultivars with flowering time (FT) that matches prevailing crop growth season help maximize their productiv - ity in the environments to which they are targeted. Dependable knowledge on genetic basis of FT enables the use of the most appropriate selection strategy to breed cultivars with desired FT. We unraveled the genetic basis by detecting QTL controlling FT using SSR markers following selective genotyping strategy (SGS) in F 2 mapping population (MP). We evaluated the effectiveness of SGS as compared to entire MP genotyping strategy (EGS) to detect QTL controlling FT. Our results suggest that alleles at two SSR markers (LPD 25 and LPD 190) are linked to QTL controlling FT in both SGS and EGS. Our results provide adequate evidence for comparable statistical power of SGS relative to EGS for detection of QTL controlling FT.

大豆花期控制QTL的选择性基因分型研究

Dolichos豆生长在作物生长季节长短的环境中。开发和部署开花时间与当前作物生长季节相匹配的品种，有助于在目标环境中最大限度地提高其生产力。通过对遗传基础的可靠了解，可以使用最合适的选择策略来培育具有所需FT的品种。我们在f2定位群体(MP)中使用SSR标记根据选择性基因分型策略(SGS)检测控制FT的QTL，揭示了遗传基础。我们评估了SGS与整个MP基因分型策略(EGS)在检测控制FT的QTL方面的有效性。我们的结果表明，两个SSR标记(LPD 25和LPD 190)上的等位基因在SGS和EGS中都与控制FT的QTL相关。我们的结果为SGS相对于EGS检测QTL控制FT的统计能力提供了足够的证据。

期刊介绍： The CBAB – CROP BREEDING AND APPLIED BIOTECHNOLOGY (ISSN 1984-7033) – is the official quarterly journal of the Brazilian Society of Plant Breeding, abbreviated CROP BREED APPL BIOTECHNOL. It publishes original scientific articles, which contribute to the scientific and technological development of plant breeding and agriculture. Articles should be to do with basic and applied research on improvement of perennial and annual plants, within the fields of genetics, conservation of germplasm, biotechnology, genomics, cytogenetics, experimental statistics, seeds, food quality, biotic and abiotic stress, and correlated areas. The article must be unpublished. Simultaneous submitting to another periodical is ruled out. Authors are held solely responsible for the opinions and ideas expressed, which do not necessarily reflect the view of the Editorial board. However, the Editorial board reserves the right to suggest or ask for any modifications required. The journal adopts the Ithenticate software for identification of plagiarism.
