“…4). This supports the results reported by Hubick (1990), Górny and Garczyński (2002), and Hamaoka et al (2013). However, Brueck and Senbayram (2009), who conducted a quantitative analysis of the influence of N supply on tobacco WUE, reported that WUE and DM proportionally increase with increases in N supply.…”

“…In this case, the reduction in WUE observed in nodulated plants casts doubt on the association with BNF and suggests that it is driven by N excess. The difference in WUE between nodulated plants and non-nodulated plants can only be directly related to N fixation cost when WUE has no relationship with the internal N conditions of plants (Hubick, 1990;Górny andGarczyński, 2002; Hamaoka et al, 2013). There is an optimum curvilinear relationship between 【Short Report】 plant growth rates and N concentration in culture medium (Hozumi et al, 1960); plant growth rates are reduced under either conditions of N shortage or N excess.…”

“…Although numerous reports on genotypic variation in components of N efficiency already suggest potential applications of this genetic knowledge for wheat improvements (Ortiz-Monasterio et al, 1997;El Bassam, 1998;Le Gouis et al, 2000;Gorny et al, 2006;Kichey et al, 2007;Baresel et al, 2008;Barraclough et al, 2010), relatively fewer attempts have been made to breed wheat for these traits (Van Ginkel et al, 2001;Wolfe et al, 2008). Progress in breeding bread wheat better adapted to less favorable nitrogen fertilization is still restricted for several reasons.…”

Because of essential economic and ecological concerns, there is increased interest worldwide in developing wheat cultivars that are more efficient in utilizing nitrogen (N) and better suited to N limitations. The objective of the present investigation was to get information on the type of gene action controlling the inheritance of wheat low-N tolerance traits in order to start a breeding program for improving such traits. Six parents of contrasting low-N tolerance were crossed in a diallel fashion. Evaluation of 6 parents, 15 F 1 crosses and 15 F 2 crosses was done using a randomized complete block design with three replications under two levels of soil N, i.e. low-N (0 kg N/ha) and high-N (180 kg N/ha).The magnitude of dominance variance in F 2 's for all studied traits was much greater than that of additive variance under both high N and low N, suggesting that selection should be postponed to later segregating generations in order to eliminate masking effects of dominance variance and take advantage of the additive variance for the improvement of nitrogen use efficiency and grain yield traits. Narrow-sense heritability (h 2 n ) in F 2 's was generally of higher magnitude under low-N than high-N, suggesting that it is better to practice selection for studied nitrogen efficiency and grain yield traits under low-N conditions to obtain higher values of selection gain.Additional keywords: gene action; NUE; NUPE; non-additive; heritability; selection gain Abbreviations used: 100-GW (100-grain weight); BYPP (biological yield/plant); GCA (general combining ability); GPS (grains/ spike); GYPP (grain yield/plant); HI (harvest index); HN (high nitrogen); LN (low nitrogen); NUE (nitrogen use efficiency); NUPE (nitrogen uptake efficiency); NUTE (nitrogen utilization efficiency); SCA (specific combining ability); SPP (spikes/plant) Authors' contributions: Conceived and designed the experiments, and supervised the work: AMMA, RS and MMA.

“…Different morphophysiological characteristics, associated with both the uptake capacity (NUpE; defined here as a proportion of total N uptake to N availability in the soil) and efficiency of nitrogen utilization in grain mass formation (NUtE; defined here as the grain mass formed per unit of N absorbed), appear to be critical components of NUE (Moll et al 1982;Huggins and Pan 2003). Although numerous reports on genotypic variation in components of N efficiency already suggest potential applications of this genetic knowledge for wheat improvements (Dhugga and Waines 1989;Le Gouis and Pluchard 1996;Ortiz-Monasterio et al 1997;El Bassam 1998;Le Gouis et al 2000;Oracka et al 2000;Górny et al 2006a;Laperche et al 2006a;Kichey et al 2007;Baresel et al 2008;Barraclough et al 2010), relatively fewer attempts have been made to breed wheat for these traits (Van Ginkel et al 2001;Brancourt-Hulmel et al 2005;Löschenberger et al 2008;Wolfe et al 2008).…”

The effects of contrasting soil nitrogen (N) levels on the inheritance of the efficiency of N uptake and N utilization in grain mass formation were examined in winter wheat. Parents of various origins and their diallel F 2 -hybrids were evaluated in field and pot experiments under varying levels of soil N. The range of additive variance in the components of N efficiency was narrow, especially under N shortage. The soil N-treatments imposed had a substantial influence on gene actions responsible for the efficiency components and modes of inheritance. Genotype 9 nutrition interactions were common. Under high N-fertilization, the efficiency components were inherited in a manner favourable for wheat selection (preponderance of additive effects). However, the enhanced contribution of non-additive gene effects and increased dominance under N-limited conditions could impede wheat selection to improve the N efficiency and adaptation to less luxurious fertilization regimes. Selection methods that eliminate masking non-additive influences and take advantage of the additive variance should be employed to improve these traits.
