Abstract:

Drought is one of the major abiotic stress factors limiting crops production in Oltenia area, Romania. In order to study the response of six maize hybrids to drought stress, the trials were conducted in research field of ARDS Simnic – Craiova, during 2017-2018 (non-stressed conditions) and 2018-2019 (drought stress). Six tolerance indices including: abiotic tolerance index (ATI), stress susceptibility percentage index (SSPI), Stress tolerance index (STI), mean productivity (MP), relative drought index (RDI) and golden mean (GM), were utilized on the basis of grain yield.

Abstract:

This study was conducted to investigate the response of maize hybrids to drought stress and to select the most drought-tolerant cultivar compared to other hybrids. The experiment was performed on six maize hybrids in a randomized complete block design (RCBD) with three replications under regular irrigation and limited irrigation in the vegetative and reproductive stages in Iran. Drought tolerance indices (TOL, MP, GMP, STI, SSI, and HAR) for the grain yield of genotypes were calculated, and principal component analysis was based on them. The results obtained from estimating the indices showed

Abstract Among all the abiotic factors affecting maize yield, drought stress is the most destructive one. Since drought tolerance is a complicated trait that is difficult to quantify, screening for stress involves measuring the effects of stress on several traits, most notably plant yield. Selection using the drought tolerance indices is an easy way to identify the stable and tolerant genotypes based on yield performances alone. The current study aims to identify suitable maize hybrids with high drought tolerance. A total of 30 maize-teosinte hybrids and 3 checks were raised under optimal and

Wheat is one of the most important crops in the world. Its yield is greatly influenced by global climate change and scarcity of water in the arid and semi-arid areas of the world. So, exploration of gene resources is of importance to wheat breeding in order to improve the crop ability of coping with abiotic stress environment. Wild relatives of wheat are rich repositories of beneficial genes that confer tolerance or resistance not only to drought but also to other environmental stresses.

To determine the resistance of soybean genotypes to drought according to drought resistance indices based on the analysis of yield in years contrasting in terms of hydrometeorological conditions. Materials and research methods. The material for determining the influence of year conditions on the level of average yield of soybeans and drought resistance were varieties and breeding numbers of the competitive variety test (CVT). Experiments were carried out in four repetitions with a plot area of 25 m2. Drought intensity (D) was determined by the for

Abstract:

Drought severely limits crop yield every year, making it critical to clarify the genetic basis of drought tolerance for breeding of improved varieties. As drought tolerance is a complex quantitative trait, we analyzed three phenotypic groups: (1) agronomic traits under well-watered (WW) and water-deficit (WD) conditions, (2) stress tolerance indices of these traits, and (3) phenotypic plasticity, using a multi-parent doubled haploid (DH) population assessed in multi-environment trials. Genome-wide association studies (GWAS) identified 130, 171, and 71 quantitative trait loci (QTL) for the thre

Abstract:

Background. Due to the global climate warming trend, the breeding of new drought-resistant cultivars of spring bread wheat remains a priority task for Western Kazakhstan breeders. However, an increase in resistance is often accompanied by a decrease in genotype productivity, and searching for an optimal combination of these characteristics is a trend in contemporary plant breeding.Materials and methods. In 2017–2019, 175 spring bread wheat accessions from the collection of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) and locally developed contemporary cultivars were

Abstract:

AbstractClimate change forecasts point to increased frequency of droughts which may affect plant growth. For protein crops such as lentil, genetic improvement of both water use and drought tolerance is necessary. Wild lentil species are known to have evolved in drought prone areas and can be introgressed into cultivated lentil, making them candidates for the evaluation of high transpiration efficiency (TE) and drought tolerance. We assessed TE, water use and drought tolerance at the plant level for five wild lentil species and in cultivated lentil. Under fully watered and moderate drought cond

Abstract:

Wheat is one of the major cereals and staple food cultivated worldwide, affected by severe environmental and climate changes. Global warming has led to significant variations in wheat production, accounting for losses up to 6.4% for each 1°C rise in temperature. Recurrent droughts in cultivable areas are anticipated to increase the risk of wheat yield loss by almost 12% by the end of the 21stcentury. The present study was undertaken to identify component traits contributing to drought tolerance and to evaluate wheat doubled haploid (DH) lines for drought tolerance using various stress toleranc

Globally, increasing water and energy demand is expected to reach 6.9 trillion cubic meters by 2030, exceeding 40% of the available water supplies. Climate change and rising temperatures caused water shortages due to lesser and irregular rainfalls, leading to lower production of crops. The research to assess drought tolerance of Pima cotton (Gossypium barbadense. L) lines in Uzbekistan revealed the line, T-450 as the most promising for drought environments.
