“…Although many factors contribute to the variation in subsurface soil temperature (Greer et al 2006), in our observations (unpublished) and in observations made by others in the Palouse region of the US Pacific Northwest, the temperature of the soil at 2Á5 cm depth (approximate depth of the crowns of winter wheat plants) is rarely less than (58C (Kahraman et al 2004;Greer et al 2006). Hence, a requirement for winter wheat to survive in the US Pacific Northwest is an ability to remain viable while frozen to (58C for months.…”

. 2008. The relationship of LT 50 to prolonged freezing survival in winter wheat. Can. J. Plant Sci. 88: 885Á889. Twenty-six wheat (Triticum aestivum L.) lines were tested for their ability to withstand remaining frozen for extended periods of time. Survival of acclimated seedlings was evaluated after remaining frozen at (58C for 15 or 20 wk. Survival after 15 wk ranged from 0 to 100% and after 20 wk ranged from 0 to 33%. The relationship of survival and LT 50 scores, the temperatures at which 50% of the plants were predicted to die, was examined with linear regression analysis. The linear relationship was highly statistically significant after 15 wk and after 20 wk. The cultivars Norstar and Froid survived being frozen for 20 wk nearly twice as well as the other cultivars; about 33% vs. 17% for the next best cultivar. These results indicated that the LT 50 score, which can be estimated in about 8 wk, reliably predicts the ability to survive in the frozen state for as long as 20 wk, and that Norstar and Froid possess a long-term freezing tolerance mechanism that is far superior to the other cultivars tested. Ces re´sultats indiquent que la LT 50 , qu'on peut estimer en a`peu pre`s 8 semaines, pre´dit de manie`re fiable la capacite´de survie au gel pendant un maximum de 20 semaines et que les cultivars Norstar et Froid posse`dent un me´canisme de tole´rance au gel nettement supe´rieur a`celui des autres varie´te´s teste´es.

“…The mean values of RILs were almost equal to the average of the mid-parent value ( Table 2), confirming that resistance to STB is under polygenic control combined with an additive effect (Kahraman et al, 2004). Moreover, the frequency distribution for the 149 RILs was not consistent with a single gene model for STB resistance and was continuous and followed normal distributions.…”

Septoria tritici blotch, causal agent Mycosphaerella graminicola (Fuckel) J. Schröt. (anamorph: Zymoseptoria tritici Desm.), is the major foliar disease of wheat (Triticum aestivum L.) in Tunisia causing frequent epidemics on T. turgidum L. var. durum (Desf.) Bowden, and important yield and grain quality losses. To determine the inheritance of resistance to septoria, a cross was made using resistant ('Salim') and susceptible ('Karim') cultivars. Parents, and the 149 derived recombinant lines, were tested for resistance to septoria under field conditions during the 2009 and 2010 crop seasons. The inheritance of resistance to septoria was quantitative where a continuous and normal distribution (W = 0.93) was shown among segregate progenies. During 2009 and 2010 crop seasons, the mean disease severities of recombinant inbred lines (RILs) ranged from 29.1% to 41.8%, respectively, and 53% of RILs were associated with lower disease severity than the mid-parent value. The severity was significantly affected by Genotype × Year interaction (p < 0.01). Broad sense heritability was 0.55 suggesting a quantitative inheritance of resistance to M. graminicola. These results would imply that genetic resistance to STB could be attributed to additive gene effects. Thus, using identified sources of tolerance to STB in a breeding program would enhance the development of cultivars that are adapted to the prevailing isolates in field conditions.

“…They make more efficient use of available moisture because the crop is established and growing when evaporative demand is minimal, and by avoiding heat stress and terminal drought at the end of growing season (Erskine & Akem, 1999). Increases in lentil yield due to winter versus spring sowing have ranged from 50% to 100% in several countries (Sakar et al, 1988;Kahraman et al, 2004a;Chen et al, 2006). Siddique et al (1998), in a study carried out in southern Australia, showed that seed yields greater than 1.0 t/ha and up to 2.5 t/ha can be achieved when sown early, and delayed sowing reduced yields by up to 30 kg/ha·day.…”

Lentil (Lens culinaris Medik. subsp. culinaris) is a traditional crop in Spain although current grain yield in Spain is relatively low and unstable. The effect of an early sowing date (winter sowing) on yield in the Spanish Central Plateau (meseta) was analyzed comparing it to the traditional spring sowing. Yield from eleven cultivars currently available for sowing in Spain and two F6:7 populations of recombinant inbred lines (RIL), ´Precoz´ × ´WA8649041´ (89 lines) and ´BGE016365´ × ´ILL1918´ (118 lines), was evaluated in winter and spring sowing dates for three seasons (2005/06, 2006/07 and 2007/08) and two localities. Yield and stability were assessed by the method of consistency of performance with some modifications. When comparing with the best currently available cultivars sown in the traditional spring sowing date, (with an estimated average yield of 43.9 g/m in our experimental conditions), winter sowing using adapted breeding lines proved to be a suitable strategy for increasing lentil yield and yield stability in the Spanish meseta, with an average yield increase of 111% (reaching an estimated yield of 92.8 g/m). Results point to that lentil production can greatly increase in the Spanish meseta if adequate plant materials, such as some of the lines analyzed, are sown at late fall.
