TAILIEUCHUNG - Breeding oats for biotic and abiotic stresses
Oats rank around sixth in world cereal production statistics, following wheat, maize, rice, barley and sorghum. In many parts of the world, oats are grown for use as grain as well as for forage and fodder, straw for bedding, hay, haylage, silage and chaff. Livestock grain feed is still the primary use of oat crops, accounting for an average of around 74 percent of the world’s total India, breeding of oats begun in nineteen-eighties and is grown as the most important cereal fodder crop in North Western, Central India, extending to the eastern a fodder crop, it has excellent protein quality, fat and mineral content. It is a palatable, succulent and nutritious diseases cause serious direct damage, mainly by reduction of the fodder yield. Among them diseases such as crown rust, stem rusts and leaf blotch. Several resistance genes against the major diseases, . crown rust, stem rust, powdery mildew, BYDY, etc., from oat gene pool have been discoveredin over 31 wild oat species. Several breeding strategies such as marker-assisted selection (MAS), marker-assisted back-crossing (MABC), markerassisted gene pyramiding and marker-assisted recurrent selection (MARS) are extensively being exploited for incorporating resistance gene introgression into elite cultivars. With the advancement of new sequencing technologies and a rapid development in bioinformatics, complete oat genome sequencing is no longer out of reach. Oat genome sequencing would pave new pathways for breeders to develop a large number of sequence-based markers such as SNPs which will help in identifying the disease resistance genes through exploiting linkage disequilibrium mapping and genomic selection. | 2020 9 1 274-283 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 9 Number 1 2020 Journal homepage http Review Article https Breeding Oats for Biotic and Abiotic Stresses Rahul Kapoor1 and Tarvinder Pal Singh2 1Forage Breeder Department of Plant Breeding and Genetics Punjab Agricultural University Ludhiana India 2Plant Breeder O o Director Seeds Punjab Agricultural University Ludhiana India Corresponding author ABSTRACT Keywords Breeding Oats Biotic and Abiotic Stresses Article Info Accepted 15 December 2019 Available Online 20 January 2020 Oats rank around sixth in world cereal production statistics following wheat maize rice barley and sorghum.
