“…Avena fatua has also been investigated for crop improvement. Dwarfing genes from A. fatua were crossed into cultivated oat cultivars for improved lodging resistance (Morikawa et al 2007). Some northcentral USA accessions had high-level tolerance to barley yellow dwarf virus (BYDV) and high groat protein content, characteristics for potential use in cultivated oat improvement (Rines et al 1980).…”

L. M. 2012. The Biology of Canadian Weeds. 27. Avena fatua L. (Updated). Can. J. Plant Sci. 92:1329Á1357. An updated review of biological information is provided for Avena fatua. A widespread species originating in Eurasia, A. fatua is one of the 10 worst annual weeds of temperate agricultural regions of the world. Key weediness traits of this highly selfing species include fecundity, seed shatter, and a large and persistent seed bank with variable degrees of primary seed dormancy. The species occurs in all Canadian provinces and most states in the USA. In Canada, it is most troublesome as a weed in the prairies, where it has spread throughout crop areas in all climatic zones. Depending upon plant density and relative time of emergence, A. fatua competition may reduce annual crop yields by as much as 70%. First cohort emergence of A. fatua coincides with planting and emergence of spring-seeded crops, although additional cohorts can emerge throughout the growing season. Avena fatua is more abundant in zerothan intensive-tillage systems; the former regime promotes earlier and greater emergence because of a shallower and less persistent seed bank. Despite the introduction of highly efficacious herbicides in the 1970s and 1980s, abundance of the species has not declined across the Canadian prairies or elsewhere. The continual evolution of herbicide-resistant A. fatua populations, seed spread via farm machinery, and limited herbicide modes of action for its control threaten sustained annual field crop production in many temperate agricultural areas. Further adoption and integration of multiple non-herbicidal weed management practices, such as enhanced crop seeding rate, competitive crops and cultivars, and precision fertilizer placement, should help mitigate A. fatua interference. The species has some beneficial uses as an alternative feed and food constituent or industrial feedstock, as well as potential in cultivated oat (Avena sativa L.) improvement.

“…In oat cultivation, however, lodging can still cause significant yield losses (Marshall et al 1986). A few dwarfing genes are available in oat that have been successfully used in the last decades by breeders, producing high-yielding varieties with lower lodging risk (Marshall and Murphy 1980;Milach et al 1997;Morikawa et al 2007). However, reducing plant height too much can have a detrimental effect on yield potential (Flintham et al 1997).…”

Sensitivity to lodging of oat varieties has been reduced in the last decades through the introduction of dwarfing genes. However, lodging may still cause significant yield loss, underscoring the need for new oat varieties with higher levels of lodging tolerance. In the present study, we analysed lodging and plant height in a collection of European oat accessions including landraces, old and modern varieties, in order to perform a genome-wide association study (GWAS) for identifying markers associated to lodging tolerance. This collection has been recently genotyped by the Infinium 6K SNP array for oat and SNP data were analysed as continuous intensity ratios, rather than as discrete genotypes (Tumino et al. 2016, Theor Appl Genet 129, pp. 1711-1724). Phenotypes for lodging severity, plant height and growth habit were collected under natural conditions in eight European countries. Plant height correlated to lodging severity as previously observed in many studies, explaining about 30% of lodging variation. GWAS analyses detected six significant associations for lodging and two for plant height. These results indicate that GWAS can successfully be used for identifying markers associated to lodging in oat, even though lodging is a quantitative trait influenced by several plant characteristics.

“…This species may constitute a source of genes determining the earliness of maturing, rapid growth, ripeness of grains, a high content of proteins, and resistance to Puccinia graminis and Puccinia coronata. There are attempts to transfer the above properties onto crop plants to improve their quality [15][16][17][18][19][20].…”

Germination of seeds of Avena fatua L. under different storage conditions

2015

Storage conditions have a strong influence on the germination of seeds of Avena fatua L, especially at variable conditions, the germination decreased. Seeds stored at a constant low temperature maintained the germination capability for 5 years. Under greenhouse conditions, seeds matured and germinated more rapidly comparing to field conditions, but individuals from these seeds were weaker and produced fewer seeds. The higher temperature in the greenhouse accelerated the development and maturing of plants. Field emergence varied depending on seed storage conditions, sample, further reproduction, and weather conditions. It was observed that individual specimens of A. fatua were able to form ripe seeds with high thousand grain mass (TGM), regardless of the occurrence of fungal diseases. The knowledge of the biology of A. fatua is very important due to its status as a restricted weed in certified seed of crop plants.
