Abstract
The difficulty of selecting for improved adaptation to heat stress makes the use of indirect measures attractive to plant breeders. To examine the response to selection on canopy temperature, leaf chlorophyll content, Fv/Fm ratio and kernel weight and to evaluate the response of some wheat genotypes facing high temperatures during and after anthesis under field conditions, ten bread wheat genotypes were exposed to two different sowing dates: normal and late sowing, to assure high temperatures during and after anthesis, in 2010-2011 in a field adjacent to Gachsaran Agricultural Research Station that is located in southwest Iran. Results indicated significant difference for all physiological traits and significant phenotypic correlation with grain yield, particularly in more heated environments. Canopy temperature explained 71 and 54.2% of grain yield variation in more and less heated environments, respectively. The lines having tolerance to high temperature during grain filling stage were marked for future breeding program.

Chlorophyll fluorescence is closely related to photosystem II (PS II), and chlorophyll fluorescence analysis has become one of the most powerful and widely used techniques that are available to plant physiologists and ecophysiologists. In this article we report the genetic study of leaf chlorophyll fluorescence traits in wheat. 114 wheat recombinant inbred lines (RILs) derived from W-7984xOpata85 were used as samples and QTLs of chlorophyll relative content (C), minimum fluorescence yield of PS ...

Heat is an important abiotic stress during wheat (Triticum aestivum L.) grain-filling in South Asia. A study was undertaken to determine effectiveness of selection for reduction in 1000-kernel weight (TKWR) under heat stress to increase grain yield. Selection was made for low and high TKWR and selected progenies were evaluated in timely and late seeded trials at two locations in Nepal in 2003. One thousand kernel weight (TKW), biomass yield, grain yield, harvest index (HI), grain-filling duratio...

Abstract Climate change could strongly affect the wheat crop that accounts for 21% of food and 200 million hectares of farmland worldwide. This article reviews some of the approaches for addressing the expected effects that climate change may likely inflict on wheat in some of the most important wheat growing areas, namely germplasm adaptation, system management, and mitigation. Future climate scenarios suggest that global warming may be beneficial for the wheat crop in some regions, but could r...

The physiological-trait-based breeding approach has merit over breeding for yield per se because it increases the probability of crosses resulting in additive gene action. While considerable investment in germplasm characterization is required, conceptual models of crop genotypes can be employed as research tools to quantify likely genetic gains associated with specific trait or in defining traits that may have generic value across different stresses. For example, deeper root growth that permits...

For over 40 years a collaborative network of publicly funded international wheat scientists has made a significant contribution to food security in the developing world. Thousands of modern wheat varieties (MVs) have been released for use in both favourable and marginal environments on well over 50 million hectares. The yield increases associated with genetic improvement in yield potential and adaptation to biotic and abiotic stresses are well documented. Millions of small-scale farmers in the d...

The development of ‘scientific’ breeding methodologies in the first half of the 20 th Century was based partly on the application of genetic theory following the rediscovery of Mendel’s Laws, but mostly on developing procedures for systematic phenotypic selection. Although, new technologies in tissue culture, pathology, statistics and quantitative genetics contributed to advances in the second half of the 20 th Century, these were limited. The last decade has seen an explosion of genetics and ge...

;The temperature dependence of the relationship between the decline in activity of photosystem II (PSII) and a chlorophyll a fluorescence parameter combining the excitation pressure (1–qP) and efficiency of excitation energy capture by open PSII reaction centers in the light-acclimated state (Fv/Fm) was investigated in cotton leaves. A formula for the prediction of PSII inactivation is proposed on the basis of the results obtained. By comparison of the predicted and actual levels of PSII photoin...

A rapid, noninvasive technique involving imaging of chlorophyll fluorescence parameters for detecting perturbations of leaf metabolism and growth in seedlings is described. Arabidopsis seedlings were grown in 96-well microtitre plates for 4 d and then treated with eight herbicides with differing modes of action to induce perturbations in a range of different metabolic processes. Imaging of chlorophyll fluorescence emissions from 96 seedlings growing on a microtitre plate enabled images of a numb...

Climate change at global and regional scales as well as increased needs for crop production is predicted, emphasizing the urgent need for introduction of crops with enhanced productivity and tolerance to unfavorable abiotic conditions. Unlike to previous breeding strategies in main crops, the future gain in yield potential can be obtained probably only through an increase of photosynthetic productivity in optimum as well as in stress conditions. This fact emphasizes the importance of photosynthe...

Alarming climate change is a worldwide documented phenomenon and increase in abiotic (temperature stress, drought, salinity) and biotic stresses (diseases, pests) have been reported worldwide in agricultural crops. Terminal heat stress is one of the yield limiting factors for wheat crop in South Asia, including Pakistan. To address this core issue, a field study was carried out at Experimental Farm of Nuclear Institute of Agriculture, Tandojam for two consecutive years 2013-14 and 2014-15 by usi...

Field crops are frequently exposed to drought and high temperature in the field. As the stress tolerance is the major target of many research and breeding programmes, the efficient and reliable tools and methods useful in screening of the heat and drought stress effects are required. The techniques based on measurement of chlorophyll fluorescence induction belong recently to fundamentals of plant stress research; however, in most cases the very basic tools are used and its potential is not utili...
