Breeding are yield-related traits such as abiotic stress tolerance pest resistance and flowering time.

Breeding for yield potential and stress adaptation in cereals. This review aims to provide an insight into common abiotic stresses. SG trait was recognized as a superior characteristic for commercially bred cereal selection to overcome the current yield stagnation in alliance with yield adaptability and stability.

Breeding programs in releasing varietieshighly adapted. Different physiological traits have been proposed as key traits associated with yield potential as well as performance under water stress. Breeding for crop adaptation requires knowledge of the germplasm and type of environmental conditions as large genotype by environment G E interactions are often observed 2225.

Beyond the Genes Abiotic cereals stresses including drought salinity and nutrient deficiency threaten plant growth and development dramatically reducing crop production and quality. Critical Reviews in Plant Sciences. This genome-wide syntenic relationship implies that other economically important cereal crops such as wheat barley maize and sorghum contain DRO1 homologs that might be useful for promoting root-related drought stress adaptations in cereals using comparative genomics.

A prospective approach for yield potential and drought and heat stress adaptation in globally important cereals. INTRODUCTIONThe use of integrative physiological traits is a valuable tool in breeding programs assisted by analytical selection for improving yield potential and stress adaptation of cereals 123. Furthermore it will aid in the utilization of the genetic potential of.

Affiliation cereal breeding department agricultural institute these values correspond to a hot and humid environment under heat stress 53 55 in the greenhouse the vpd was. Breeding for functional SG has contributed in improving crop yields particularly when it is combined with other useful traits.

Breeding efforts however placed yield rather than survival into the focus of crop especially cereal improve-mentAs high-yielding cereal cultivars became widespread in agriculture yield safety gained more and more impor-tance. The potential yield gains are substantial considering that abiotic stress can reduce average yields of major crops by 50 Bray et al2000 and pests can cause 2640 yield losses Oerke2006. Yield potential and stress adapt ation in cereals 379 Plant adaptation is a key factor that will determine the future severity of the effects of climatic change on food production.

Breeding for short- or long-duration varieties is therefore a common breeding strategy to maximise yield and adaptation to specific environments. In gain yield could include adaptation to these changes. When breeding for yield potential and adaption to abiotic stresses such as drought carbon isotope discrimination Δ 13 C in dry matter is a promising tool that frequently exhibits high heritability and genetic correlation with yield 66 67 68 and has already been applied to breeding programs.

Breeding for Yield Potential and Stress Adaptation in Cereals JoseLuisAraus 1 Gustavo A. But avoidance mechanisms may limit yield potential when conditions are favorable as the crop duration may be too short to achieve maximum yield. Abiotic stresses such as extreme temperatures and low water availability frequently limit the growth and pro-.
