“…MSTIk2 showed high positive correlation with Ys for all the stress intensities; while its relationship with Yp seemed to be always moderate (Table 3). This is in concordance with Farshadfar and Elyasi (2012); and Gholinezhad et al (2014) studies. This result can be explained by the formula which favors the yield under stress conditions (correction coefficient) rather than the yield potential.…”

“…These findings are in concordance with the results of Moosavi et al (2008), , Rahmani et al (2013) and Gholinezhad et al (2014). However, significant positive correlation of 0.36 and 0.56 were observed between ATI and Ys at stress intensities of 0.25 and 0.35 respectively, which, however disappeared at 0.57 (Table 3).…”

“…However, Rahmani et al (2013) found an absence of correlation of Yp with HARM, GMP and STI under severe stress (0.6). Moreover, the association between yield and RDY was observed at slight moderate stress (Farshadfar and Elyasi, 2012); moderate Gholinezhad et al, 2014) and severe stress level (Gholinezhad et al, 2014). Similar to our findings, REI and MRP were useful in identifying genotypes with high yield potential in Bennani et al (2016).…”

“…The indices YI, DI, SNPI and SSPI showed strong positive correlation only with Ys except the moderate correlation for SSPI at 0.57 stress intensity (Table 3). The same findings were found in Moosavi et al (2008) and Gholinezhad et al (2014). On the other hand, negative correlation characterized the relationship between Ys and DRI at 0.25 and 0.57 as stated by and Ys with b and bN at severe stress level only (0.57) as indicated in Mohammadi et al (2010) and Akçura and Ceri (2011) studies.…”

Drought is a world-wide spread problem adversely affecting bread wheat production in rainfed agro-ecosystems. Development and identification of efficient selection criteria for developing drought tolerant wheat varieties with stable and high yield potential is of paramount importance. This study was carried out to evaluate 24 indices for selecting the best high yielding and drought tolerant cultivars, among 40 bread wheat genotypes, under four levels of stress intensities: no stress, mild (0.25, 0.35) and severe (0.57). The mean productivity (MP), modified stress tolerance index (MSTIk), superiority index (Pi), mean relative performance (MRP), relative efficiency index (REI), geometric mean productivity (GMP), stress tolerance index (STI), harmonic mean (HARM) and relative decrease in yield (RDY) showed a high power of discrimination among genotypes, and expressed significant correlations with yields under both stress and non-stressed conditions at all stress intensities. This group of indices was capable to select the highest mean yield associated with the least mean variance at 20 % selection pressure. However, as the stress intensity became greater (>35 %), the efficiency of these indices decreased, especially at high stress intensity (57%), where only Pi and MP were still able to target the highest performances. MRP, REI, GMP, RDY and STI can be used interchangeably. Based on GGE analysis, the best performing genotypes were AUS30355, followed by Gladius, Amir-2 and AUS30354 that showed high yield and stability across all the environments. These genotypes are recommended for direct release and/or for use as parents in the breeding programs.

“…To manage this situation, it is important to use the percentage decrease or tolerance indices in relation to the control average for genotype classification. Many studies used salt tolerance indices and biplot analysis to screen stress-tolerant genotypes (Mitra 2001, Farshadfar and Sutka 2002, Mohammadi et al 2010, Gholinezhad et al 2014. In general, the salt tolerance indexes were reduced in salt-sensitive genotypes with increasing salinity.…”

In this study, we examined the behavior of six faba bean (Vicia faba L.) genotypes under salinity conditions at the seedling stage. The evaluation was assessed using 21 morphological, physiological, and photosynthetic traits under control, moderate, and severe salinity conditions. The principal component analysis (PCA) was used to identify genotypes of contrasting behavior in response to salt stress and to characterize the important traits for salt tolerance. The result of PCA analysis showed that the genotypes displayed different behavior under the saline conditions. The most discriminating quantitative characters were related to plant biomass production and photosynthesis, especially the mass of fresh root, number of leaves, water-use efficiency, and the substomatal CO2 concentration. The analysis of all parameters by PCA permits us to distinguish cv. Najeh as the most tolerant genotype for salinity conditions and cv. Chourouk as the most sensitive one. These results would be of pertinent tools in faba bean breeding programs.
