Importance of QTL Mapping for Heading Date in Rice
Heading date in rice is one of the most important indices in rice breeding being governed by multiple genes known as quantitative trait loci (QTLs). This character along with grain yield determines the commercial potential of any rice cultivar. In the last three decades the development of DNA markers have led to the precise analysis of QTLs. Various mapping populations are being used to explore...
متن کاملDissection of genetic architecture of rice plant height and heading date by multiple-strategy-based association studies
Xieyou9308 is a certified super hybrid rice cultivar with a high grain yield. To investigate its underlying genetic basis of high yield potential, a recombinant inbred line (RIL) population derived from the cross between the maintainer line XieqingzaoB (XQZB) and the restorer line Zhonghui9308 (ZH9308) was constructed for identification of quantitative trait SNPs (QTSs) associated with two impo...
متن کاملGenetic dissection of QTLs and differentiation analysis of alleles for heading date genes in rice
Heading date is an important agronomic trait in rice (Oryza sativa L.); it determines the geographical and seasonal adaptability of the crop. Single segment substitution lines (SSSLs) have become the preferred experimental materials in mapping functional genetic variations as the particular chromosome segments from donor genotypes can be evaluated for their impact on the phenotype in a recurren...
متن کاملCharacterization of genetic variation among accessions of Aegilops tauschii
* Author for correspondence: Agronomy and Plant Breeding Department, Agricultural College, University of Tehran, Karaj, Iran. Tel: 02612246074, Fax: 02612227607, Email: [email protected]. Abstract. The application of AFLPs, and SSRs to examine genetic relationships in the 54 accessions of Aegilops tauschii from 5 countries was investigated. A total of 256 (234 polymorphic) and 224 (219 polymorp...
متن کاملGenetic architecture of main effect QTL for heading date in European winter wheat
A genome-wide association study (GWAS) for heading date (HD) was performed with a panel of 358 European winter wheat (Triticum aestivum L.) varieties and 14 spring wheat varieties through the phenotypic evaluation of HD in field tests in eight environments. Genotyping data consisted of 770 mapped microsatellite loci and 7934 mapped SNP markers derived from the 90K iSelect wheat chip. Best linea...
