“…So genotypes adjustments to drought stress and have high yield in normal and stress conditions, they have high geometric and harmonic means and nominated drought resistance genotypes (Abebe et al 1998). In this study, 2 and 7 genotypes had the least and the most GMP and HM indices, so they are nominated sensitivity and resistance genotypes, respectively.…”

Context: Evaluation of tolerance of different barley genotypes to drought stress, an experiment carried out in randomized block design (RCBD) with three replication during 2009-2010 growing seasons and 20 barley genotypes were studied in normal and water deficit in post anthesis stage conditions at the Saatloo Research Farm Azerbaiejan, Iran. Results:The result of variance analysis showed that there were highly significant differences between genotypes in all of the studied traits, also it was cleared that all of traits except spike length reduced in water deficit condition as compared to normal condition and seed yield, biomass and 1000 seed weight traits had the most reduction (31, 25 and 20 percent, respectively). To identify of tolerance barley genotypes to drought stress, drought tolerance indices (STI, TOL, SSI, MP, HM and GMP), correlation coefficients, principal components analysis and cluster analysis were used. The result of correlation coefficients indicated that there were significant and positive correlation between seed yield in normal and stress conditions and drought tolerance indices. Also the result of principal components analysis showed that two components justified 99% of total variations. MP, GMP, STI and HM indices and TOL and SSI indices had the most coefficients in the first and second component, respectively, so are named tolerance and sensitivity component, respectively. Conclusion: MP, HM, STI and GMP indices were appropriate indices to select of drought tolerance barley genotypes. On the other hand, the result of cluster analysis showed that 13, 14 and 7 genotypes and 18, 1 and 2 genotypes were tolerance and sensitivity genotypes to water deficit at post anthesis stage.

“…Drought resistance is a complex trait, expression of which depends on action and interaction of different morphological, physiological and biochemical characters (Mitra 2001). Genotypic differences for drought resistance have been reported for common bean (Abebe et al, 1998). The most effective selection criterion, among various morphological, physiological, phenological, yield, and yield related traits, for identifying drought resistant genotypes was mean seed yield (the arithmetic and geometric) of drought stress and non-stress environments (Abebe et al, 1998).…”

Information on the response of basic generations of a population to drought stress may help in designing effective breeding procedure and identification of selection criteria that can be used to develop suitable cultivars. This study was carried out to ass differential effects of drought stress initiated at flowering stage on the growth, physiological and yield related traits of six basic generations of two common bean populations made of crosses between pairs of drought resistant and susceptible par Melka-Dima X SAB623). On average, the stress imposed reduced the various characters examined in the range of 3% (pod length) to 28% (seed yield). Canopy temperature and chlorophyll content, however, increased in response to the stres two populations were compared, those obtained from Melka sensitive to drought than Roba 1 X SERsusceptible parents (Roba 1 and Melka-Dima) had the highest dr in growth, stomatal conductance and all yield related traits whereas P1, F1 and BC1 exhibited better performance under drought stress for the different characters studied. Under drought, F1 generation produced higher seed yield than indicating the presence hetrosis under the stress condition. With geometric means of 3722 and 4077, F1 and P1 were found to be the most drought resistant generations in Roba 1 X SER-16 and Melka-Dima X SAB-623 crosses, respectively drought stress of these generations was associated with the maintenance of higher stomatal conductance, leaf area and aboveground biomass as well as greater ability to remobilize biomass to reproductive sinks (pods and seeds).

“…Drought stress can also reduce biomass yield, number of seeds and pods, days to maturity, harvest index, seed weight, nitrogen partitioning, nodulation, and biological nitrogen-fixation (Foster et al 1995;Castellanos et al 1996;Ramirez-Vallejo and Kelly 1998). Abebe et al (1998), Acosta et al (1999), Singh and Terán (1995), and Terán and Singh (2002) reported genotypic differences for drought resistance in common bean. Moreover, the highest levels of drought resistance were found in Durango race cultivars from the Mexican highlands (Singh and Terán 1995;Terán and Singh 2002).…”

“…Moreover, the highest levels of drought resistance were found in Durango race cultivars from the Mexican highlands (Singh and Terán 1995;Terán and Singh 2002). Among various morphological, physiological, phenological, yield, and yield-related traits to identify drought-resistant genotypes, mean seed yield (the arithmetic and geometric) of DS and NS environments was found to be the most effective selection criterion (White et al 1994a;Abebe et al 1998;Ramirez-Vallejo and Kelly 1998). Narrow-sense heritability for seed yield under drought stress ranged from 0.09 ± 0.19 to 0.80 ± 0.15 (White et al 1994b;Singh 1995;Schneider et al 1997b).…”

Terán, H. and Singh, S. P. 2002. Selection for drought resistance in early generations of common bean populations. Can. J. Plant Sci. 82: 491-497. Availability and use of high-yielding drought-resistant common bean (Phaseolus vulgaris L.) cultivars would reduce dependence on irrigation water and production costs, stabilize yield in drought-prone environments, and potentially increase profit margins for growers. Among various selection criteria, seed yield has been found to be the most effective to improve drought resistance in common bean. Our objective was to determine the effectiveness of selection for seed yield in drought-stressed (DS) and non-stressed (NS) environments in early generations of common bean populations under field conditions. One hundred thirty-four F 2 -derived F 4 (F 2:4 ) families from each of three double-cross populations (SX 12008, SX 12009, and SX 12010), four parents, and six checks were evaluated in replicated field trials in DS and NS environments at the Centro Internacional de Agricultura Tropical, Palmira, Colombia during the January to March growing season (1997A). The 30 highest yielding F 2:5 families from each population and each environment, four parents, and two checks were again evaluated in replicated trials in their respective DS and NS environments during the June to August growing season (1997B). Three F 5:7 lines from each of the four highest yielding F 2:5 families from each population and each environment (a total of 72 lines), and nine parents involved in the three populations were evaluated in replicated trials in both DS and NS environments in 1998B and 1999B. Mean yield of lines selected in the NS environment was significantly higher than the mean of parents in populations SX 12008 and SX 12010 when tested in the NS environment. In population SX 12009, lines selected in the DS environment had higher mean yield than their parents when tested in NS environment. The mean yields of lines selected in the DS and NS environments did not differ significantly when tested in the DS environment in any population. NS environment seed yields were positively correlated with DS yields, geometric mean yield (GM), percent reduction (PR) due to drought stress, and drought susceptibility index (DSI). In contrast, DS and GM yields were negatively correlated with PR and DSI, whereas the association between the latter two was positive. The 100-seed weight was slightly reduced and mean maturity was accelerated by 2 to 4 d in DS versus NS environments. Considering the extra costs involved to test early generation selections for seed yield in DS environments, it does not appear to be advisable in common bean.
