Recurrent genomic selection for wheat grain fructans

Valuations of Variables as Selection Index for Improving Grain Yield in Bread Wheat

Identifying selection indices is the most important step of a breeding project that aims to improve grain yield. The definition of the selection index is usually done by evaluating the variables in multivariate statistical methods. In the present study, the relationship between grain yield and its components in bread wheat genotypes was determined by multivariate statistical methods. The experi...

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 ...

Comparison of Genomic Selection Models to Predict Flowering Time and Spike Grain Number in Two Hexaploid Wheat Doubled Haploid Populations

Genomic selection (GS) is becoming an important selection tool in crop breeding. In this study, we compared the ability of different GS models to predict time to young microspore (TYM), a flowering time-related trait, spike grain number under control conditions (SGNC) and spike grain number under osmotic stress conditions (SGNO) in two wheat biparental doubled haploid populations with unrelated...

Heritability of Grain Yield and Its Components and Selection for Drought Tolerance in Wheat Double Haploid Lines

Drought is one of the most important environmental factors affecting plant growth. The double haploid method is one of the most common breeding methods in wheat. Using old cultivars in cross-breeding programs can be effective for restoring genes lost during evolution. In this study, in order to evaluate the genetic diversity and to select the drought-tolerant introgression wheat lines, 151 doub...
