Mapping of QTLs underlying flowering time in sorghum [Sorghum bicolor (L.) Moench]
Due to its critical importance in crop yield, the photoperiodic regulation of flowering time is considered an important trait in sorghum breeding programs. In this study, quantitative trait loci for flowering time were detected using an F(2) population derived from a cross between Kikuchi Zairai, a late-flowering cultivar originating from Japan and SC112, an early-flowering cultivar originating...
متن کاملMapping QTLs Controlling Flowering Time and Important Agronomic Traits in Pearl Millet
Pearl millet [Pennisetum glaucum (L.) R. Br.] is a staple crop for the people of arid and semi-arid regions of the world. It is fast gaining importance as a climate resilient nutricereal. Exploiting the bold seeded, semi-dwarf, and early flowering genotypes in pearl millet is a key breeding strategy to enhance yield, adaptability, and for adequate food in resource-poor zones. Genetic variation ...
متن کاملAssociation Mapping of Flowering Time QTLs and Insight into Their Contributions to Rapeseed Growth Habits
Plants have developed sophisticated systems to adapt to local conditions during evolution, domestication and natural or artificial selection. The selective pressures of these different growing conditions have caused significant genomic divergence within species. The flowering time trait is the most crucial factor because it helps plants to maintain sustainable development. Controlling flowering...
متن کاملCandidate gene association mapping of Arabidopsis flowering time by
The pathways responsible for flowering time in Arabidopsis thaliana comprise one of the best-characterized genetic networks in plants. We harness this extensive molecular genetic knowledge to identify potential flowering time quantitative trait genes (QTGs) through candidate gene association mapping using 51 flowering time loci. We genotyped common single nucleotide polymorphisms (SNPs) at thes...
متن کاملGenetic and Phenotypic Variation for Flowering Time Genes in Barley (Hordeum vulgare)
Objective: Flowering Time (FT) in cereals controlled by genes that had a main factor on plant development. Methods: Genetic and phenotypic diversity of four flowering time genes (FT2, FT3, FT4, Ppd-H1) in 19 genotypes of cultivated and wild barley was evaluated and a total of 107 alleles were amplified. Genotypes based on days to flowering time and molecular data were grouped into earl...
