Abstract: A set of thirty-six wheat cultivars were grown for two consecutive years under low and high nitrogen conditions. The interactions of cultivars with different environmental factors were shown to be highly significant for most of the studied traits, suggesting the presence of wider genetic variability which may be utilized for the genetic improvement of desired trait(s). Three cultivars, i.e., RAJ 4037, DBW 39 and GW 322, were selected based on three selection indices, i.e., tolerance index (TOL), stress suscept… Show more

“…A similar 10% increase in grain yield under high compared with low N conditions in southeastern European environments was also reported in a panel of 48 winter wheat cultivars by Ivić et al [41]. Belete et al [5] and Tyagi et al [42] also observed significant grain yield difference among wheat cultivars and N condition, showing that the cultivars also contrasted in terms of responsiveness to N supply, which is similar to the results of the current study. Mansour et al [16] also reported that grain yield of wheat was doubled from 2794 kg•ha −1 at no N to 7245 kg•ha −1 at 208 kg•N•ha −1 when averaged across all genotypes.…”

“…is idea also draws support from reports of Tyagi et al [42], who also used four common selection indices to identify low N-tolerant wheat cultivars. Similar to the criteria used in the present study for low N tolerance/N-efficiency, Chen et al [46] also reliably used total N uptake and NUE to assess the ability of low N tolerance during screening tea cultivars.…”

“…Guendouz, Guessoum, and Hafsi (2012) used different selection indexes to identify wheat genotypes tolerant to water deficit. Tyagi et al (2020) also used indexes to select wheat genotypes tolerant to environments with low nitrogen availability. However, most works carried out until now have focused on simultaneous selection applied to phenotypic values, which can represent high estimates of gains with the selection.…”

“…Noureldin et al (2013) also reported that there were significant differences among the wheat cultivars in terms of vegetative and reproductive traits under different levels of nitrogen application. Tyagi et al (2020) also emphasized the role of genotype and breeding programs in nutrient intake and producing high-yielding wheat varieties for low nitrogen conditions.…”
