“…To determine whether a genetic association exists between Qss.msub‐3BL and grain yield, the proportion of phenotypic variation accounted for by the marker alleles was computed ( R 2 ). Only Xgwm247, Xgwm340, and Xgwm547 were used in this calculation because they are the most closely associated markers to Qss.msub‐3BL An R 2 of 0.01 showed the marker allele genotype was not significantly associated with yield (Table 2) These results are consistent with reports by Lebsock and Koch (1968), McNeal and Berg (1979), and Hayat et al (1995), suggesting that the major gene for solid stems does not have a deleterious effect on yield.…”

“…Some studies have reported a negative correlation between stem solidness and yield (McNeal et al, 1965; Wallace and McNeal, 1966; Weiss and Morrill, 1992). Other studies, however, have shown no correlation between stem solidness and yield (Lebsock and Koch, 1968; McNeal and Berg, 1979; Hayat et al, 1995).

“…Early research showed a significant negative correlation between stem solidness and yield (McNeal et al, 1965). However, more recent studies have indicated a nonsignificant genetic correlation between stem solidness and yield (Lebsock and Koch, 1968; McNeal and Berg, 1979; Hayat et al, 1995). Hayat et al (1995) attributed low yield in solid stem cultivars to the poor genetic background of the solid stem source rather than pleiotropy or deleterious linkage.…”

Wheat stem sawfly (WSS), Cephus cinctus N., is a major insect pest of winter and spring wheat, Triticum aestivum L., in areas of the northern Great Plains. The primary control measure is use of resistant cultivars containing solid stems. Environmental effects on expression of the trait can be problematic, thus genetic markers would be useful. In this study, a doubled haploid (DH) winter wheat population derived from a ‘Rampart’ (solid stems) × ‘Jerry’ (hollow stems) cross was analyzed to identify molecular markers linked to genes controlling stem solidness. The DH population was genotyped with GWM and BARC microsatellite primers that spanned the wheat genome. To genotype the population efficiently, bulked segregant analysis (BSA) was used to identify polymorphism between groups of solid stem and hollow stem individuals. Four microsatellite markers (GWM247, GWM340, GWM547, and BARC77) were found linked to a single solid stem QTL (designate Qss.msub‐3BL) on chromosome 3BL. However GWM247, GWM340, and GWM547 were found to be more closely linked to the QTL than BARC77. Single marker analysis showed Qss.msub‐3BL contributes at least 76% of the total variation for stem solidness. Additionally, no significant relationship existed between Qss.msub‐3BL and other agronomic traits, including yield. These microsatellite markers (GWM247, GWM340, and GWM547) will be useful for selecting solid‐stemmed wheat cultivars to help control the wheat stem sawfly.

Solid-stemmed spring wheat cultivars (Triticum aestivum L.) are resistant to the stem sawfly (Cephus cinctus Nort.) and lodging. Anthers of 24 spring wheat cultivars with varying content of pith in the stem were used in the experiment. All were classified into three groups: solid, medium–solid and hollow stems. There was considerable influence of the cultivar on callus formation and green plant regeneration. The highest efficiency of green plant regeneration (24%) was observed for the solid-stemmed AC Abbey cultivar. There was no regeneration from the explants of four cultivars: CLTR 7027, Alentejano, Marquis and Bombona. Principal component analysis showed no differences between the cases under observation (callus induction and green plant regeneration) in their response to pre-treatment temperatures (4 and 8°C). The examination of the effects of various auxin types in the induction medium on callus formation and green plant regeneration revealed that the strongest stimulation of these processes was observed in the C17 medium with 2,4-D and dicamba. The efficiency of callus formation and green plant regeneration was greater in solid-stemmed cultivars than in hollow-stemmed cultivars.

“…All solid‐stemmed spring and winter wheat cultivars developed to date derive resistance from the line S‐615 (Kemp, 1934; Platt and Farstad, 1946), but two other sources exist (Clarke et al, 2005). The recessive nature of the genes controlling resistance derived from S‐615 leads to inconsistent pith expression in the field (Hayat et al, 1995). This was acknowledged shortly after ‘Rescue’ was released when observations of high susceptibility to stem cutting were noted at Regina, SK (Platt and Farstad, 1949).…”

The wheat stem sawfly (Cephus cinctus Norton [Hymenoptera: Cephidae]) is a serious threat to wheat (Triticum aestivum L.) and other cereal grains in the northern Great Plains. Wheat cultivars with high expression of pith in the culm of the stem (stem solidity) can minimize losses associated with sawfly infestations and subsequent stem boring of the larva. Based on the widespread area now sown to solid‐stemmed wheat, our objective was to develop an integrated nutrient and planting strategy specific to solid‐stemmed spring wheat using modern farming techniques. Five levels of banded N fertilizer (0, 30, 60, 90, and 120 kg N ha−1) were arranged in a factorial combination with three levels of sowing density (100, 300, and 500 seeds m−2) and grown at three sites in southern Alberta, Canada, from 2007 to 2009. Increased planting densities optimized yield, but an inverse relationship with pith expression (stem solidness) was observed. Low plant populations (100 seeds m−2) were often most effective at maximizing pith expression in solid‐stemmed wheat and reducing sawfly cutting damage. However, this usually required the highest rates of N fertilizer, so a system of low seeding rates and high N may not be economical based on fertilizer input costs and the generally lower grain yield response (−9%). An integrated planting and nutrient strategy for solid‐stemmed spring wheat cultivars consists of seeding rates no greater than 300 seeds m−2 and basal N applications in the range of 30 to 60 kg N ha−1.
