Many candidate physiological traits have been suggested for wheat improvement under moisture stress and genetic diversity is present in the wheat gene pool for most of them. The objective of this study was to quantify the probable yield effect associated with variation in the expression of such traits within two sets of germplasm;Sisters(from an elite x elite cross) showing a range of drought adaptation, andDiverselines (representing synthetic-derived wheat as well as selected landraces) assembl...

Summary As farmers increasingly adopt resource conserving farming practices, there is a need for wheat cultivars that better adapt to the changing environment and the nutritional needs of people, particularly those living in developing countries. Improved adaptation to zero and minimum tillage, better water use efficiency, improved root health, durable resistance to foliar diseases and enhanced nutritional value of the grain are key selection criteria for plant breeders. Significant responses to...

Summary Breeding for adaptation to abiotic stress is extremely challenging due to the complexity of the target environments as well as that of the stress-adaptive mechanisms adopted by plants. While many traits have been reported in the literature, these must be considered with respect to the type of environment for which a cultivar is targeted. In theory, stress-adaptive traits can be divided into groups whose genes and/or physiological effects are likely to be relatively independent such that ...

The impact of wheat (Triticum aestivum L.) germplasm from the International Maize and Wheat Improvement Center (CIMMYT) in the highly productive environments of the developing world has been significant. However, 55% of the area sown to wheat in these countries is periodically affected by drought and the impact of CIMMYT germplasm on productivity in these areas is not dear. Our objective was to measure rates of yield improvement for the period 1979 through 1998 using yield data from CIMMYT's Eli...

Abstract A set of 10 bread wheat ( Triticum aestivum L.) and six durum wheat ( T. turgidum L.) genotypes near-isogenic for either the Rht 1 or Rht 2 dwarfing genes were analyzed for plant height, kernel weight, coleoptile length and grain yield. Coleoptile length was measured at three different temperatures and plant height, kernel weight and grain yield determined in six different environments. Durum wheat, regardless of stature, produced longer coleoptiles than bread wheat at higher temperatur...

Understanding the relationship among yield testing locations is important if plant breeders are to target germplasm better to different production environments or regions. To examine the relationship among international drought prone test sites, yield data from 122 locations, sown during a 6-yr period in CIMMYT's Semi-Arid Wheat Yield Trial (SAWYT) were analyzed. The shifted multiplicative model (SHMM) was used to group locations within each year and pattern analysis was employed to group those ...

Abstract Intensive cultivation of irrigated wheat in 30 m ha area is mainly causing the depletion of groundwater resources in India. This calls for urgent technological interventions to improve the water productivity of wheat for sustaining the profitability of farmers. Seventy-one genetically diverse wheat genotypes were screened for high water use efficiency (WUE) under limited soil moisture level at 60% of Cumulative Pan Evaporation (CPE) during 2015-16. Out of these best performing sixteen h...

Assessment of quantitative traits in bi-parental progenies provides a strategy to identify drought tolerant genotypes and stress-adaptive traits in wheat. A recombinant inbred line (RIL) population with 167 lines produced from the SeriM82/Babax cross was subjected to normal irrigation and drought stress (at the heading stage) under field conditions. The study was done in Bajgah, Shiraz, Fars province, Iran, during three consecutive seasons. Shiraz is located in a temperate, major wheat productio...

In light of anticipated climate change, we assessed the possibility to use an airborne platform to measure canopy temperature (CT) and the normalized differential vegetation index (NDVI) as well as the suitability of both traits for their use in breeding for tolerance to heat stress. We evaluated 71 subtropical maize (Zea mays L.) hybrids under heat stress and combined heat and drought stress in an environment with average temperatures of 29.8°C during the growing season and 31.2°C during the fl...

Global food security is at high risk due to depletion of natural resources and climate change. In that context wheat has a pivotal position because wheat is a major cereal. Tremendous advances in wheat improvement had been made through above ground parts in recent years without considering roots as a plant part. Existing wheat varieties have small and inefficient root systems that need to be replaced with extensive and efficient root system. Better roots can improve utilization of water and nutr...
To evaluate the quantitative and qualitative responses of barley to foliar molybdenum in drought conditions, an experiment was conducted in 2013 in the Research Farm of Islamic Azad University of Shiraz. The experiment was iterated four times as split plots in the form of statistical design of randomized blocks. Main plots involved three levels of irrigation regimes including normal irrigation, mild stress (no irrigation at the beginning of grain filling) and high stress (no irrigation at early ...

Heat and drought are the most important wheat production constraints worldwide. The objectives of this research were to evaluate the independent and combined effects of drought and heat in SeriM82/Babax population. Genotypes showed 11, 38 and 52% losses in grain yield (YLD) in 2010–11 and 18, 25 and 48% in 2011–12 under heat, drought and combined stress, respectively. Seri M82 had higher YLD than Babax under heat and combined stress. Grain per spike and canopy temperature at vegetative stage (CT...

Nineteen wheat genotypes were used to examine the effects of foliar applied glycine betaine (GB, 100 mM) on concentration of various osmolytes (such as proline, choline, GB and sucrose) under drought stress conditions. Drought stress caused a significant increase in proline content and GB content of wheat genotypes, both at maximum tillering and anthesis stages. Choline and sucrose were accumulated significantly at higher levels under stress conditions at both the stages. GB application increase...
