genes; quantitative trait loci; seed dormancy; sprouting; winter wheat
Abstract:
... Seed dormancy and pre-harvest sprouting are important traits in bread wheat. Bi-parental populations have permitted the identification of several genes/quantitative trait loci controlling these traits, mapping to various bread wheat chromosomes. Here, we report the use of association mapping to uncover the genetic basis of both traits in a panel of 96 diverse winter wheat cultivars to establish th ...

Abstract:
... Creeping bentgrass (Agrostis stolonifera L.) is the most widely cultivated and high-value turfgrass species. Genetic linkage maps of creeping bentgrass were constructed for quantitative trait loci (QTL) analysis of gray snow mold (Typhula incarnata) resistance, recovery and leaf width. A segregating population of 188 pseudo-F₂ progeny was developed by two-way pseudo-testcross mapping strategy. Amp ...

Abstract:
... Yield gains in orchardgrass (Dactylis glomerata L.), like most cool-season grasses, have lagged compared to other crop species. The development of synthetic varieties may capitalize on combining ability: mother genotypes are selected after progeny testing. The progenies are obtained from polycrosses and their performance is a measure of the general combining ability (GCA) of the mother genotypes. ...

... Preharvest sprouting (PHS) in spring wheat (Triticum aestivum L.) and durum wheat (T. turgidum L. var durum) causes significant economic losses due to a reduction in grain yield, grain functionality and viability of seed for planting. Average annual estimated losses in Canada are about $100 million. Genetic resistance to PHS reduces these losses. Development of PHS resistant cultivars is complicat ...
