Recurrent Selection for Kernel Weight in Spring Wheat
reported grain yield increased 3.9 and 7.4% cycle 1, respectively, over two cycles of selection in barley Increasing kernel weight has been proposed as a method to increase (Hordeum vulgare L.). Durum wheat (Triticum turflour extraction in spring wheat (Triticum aestivum L.). Recurrent selection was initiated to increase kernel weight while maintaining gidum L. var. durum) grain yield improved ...
متن کاملPCR-based markers for identification of some allelic variation at Glu-1 and Glu-3 loci in common wheat
Marker assisted selection (MAS) is a tool for breeding, screening, and genetic characterization of germplasm. Allelic variation of both high and low molecular weight glutenin subunits (HMW/LMW-GS) is associated with the rheological properties of wheat flour. In this study, we investigated glutenin pattern using SDS-PAGE and their PCR based on DNA markers in 60 advanced wheat lines and cultivars...
متن کاملeffects of nitrogen and aba application on basal and distal kernel weight of wheat
individual grain weight of wheat kernels differs with their positions on a spike. cultivation practices (such as fertilizer nitrogen and plant growth regulators application) can be used to improve weight of basal and distal kernels. for this purpose, two experiments based on randomized complete block design were carried out with three replications. the aim of this research was to study the mech...
متن کاملHaplotypes of the TaGS5-A1 Gene Are Associated with Thousand-Kernel Weight in Chinese Bread Wheat
In previous work, we cloned TaGS5 gene and found the association of TaGS5-A1 alleles with agronomic traits. In this study, the promoter sequence of the TaGS5-A1 gene was isolated from bread wheat. Sequencing results revealed that a G insertion was found in position -1925 bp of the TaGS5-A1 gene (Reference to ATG), which occurred in the Sp1 domain of the promoter sequence. Combined with previous...
متن کاملAllelic variation at the vernalization and photoperiod sensitivity loci in Chinese winter wheat cultivars (Triticum aestivum L.)
A total of 205 wheat cultivars from the Yellow and Huai valley of China were used to identify allelic variations of vernalization and photoperiod response genes, as well as the copy number variations (CNVs) of Ppd-B1 and Vrn-A1 genes. A novel Vrn-D1 allele with 174-bp insertion in the promoter region of the recessive allele vrn-D1 was discovered in three Chinese wheat cultivars and designated a...
