“…In the group of the analyzed varieties, the largest diameter of the first and second internode was observed in common wheat Kontesa (3.510 mm) and winter spelt Poeme (3.513 mm), and the smallest -in spring spelt Wirtas and Rubinas (2.693 and 2.798 mm, respectively). The second internode diameter was larger than the first internode diameter in all evaluated forms, which is a characteristic trait of common wheat and durum wheat (Kelbert et al, 2004a;Segit et al, 2005). The diameter of both internodes is larger in common wheat cultivars that are resistant to lodging than in sensitive varieties (Klebert et al, 2004a).…”

“…Kelbert et al (2004a) observed considerable differences in stem wall thickness in the second internode region between common wheat cultivars that are resistant and sensitive to lodging (0.75 mm and 0.69 mm, respectively). Similar results were reported in a study of four common wheat genotypes, where a positive correlation was noted between lodging resistance vs. stem wall thickness (R = 0.972) and the weight of three lowest internodes (R = 0.986) (Kong et al, 2013).…”

“…In common wheat, resistance to lodging is highly correlated with plant height as well as stem diameter, stem wall thickness, mechanical layer thickness, and area of transverse section (Kelbert et al, 2004a;Kong et al, 2013;Wang et al, 2006;Zuber et al, 1999). Higher values of the above traits are indicative of increased resistance to lodging.…”

“…The correlations between lodging resistance and the number and size of vascular bundles in the stem cross-section have been investigated by numerous authors (Kelbert et al, 2004a;Kong et al, 2013;Wang et al, 2006;Zuber et al, 1999;Żebrowski, 1992a). The role played by vascular bundles in lodging resistance of wheat has not yet been fully explained.…”

“…The correlations between various plant traits and lodging resistance have been widely studied, but an index of resistance traits that could be used in breeding programs has not yet been developed. In wheat breeding programs, plant height remains the most practical and easily selectable trait for lodging resistance (Kelbert et al, 2004a;Zuber et al, 1999). Lodging resistance should be one of the major goals of minor cereals breeding in Europe.…”

A b s t r a c t. The cross-sections of first and second internodes were analyzed under a light and fluorescence microscopes in six varieties of Triticum spelta, two varieties of T. polonicum, and one variety of T. aestivum. The morphometric parameters of stem cross-sections were measured. The analyzed wheats were characterized by significant differences in traits associated with lodging resistance ie: internode diameter, lumen diameter, stem wall thickness, mechanical layer thickness, area of transverse section, and area of lumen for the first and second internode and between the internodes. In all varieties, the values of internode diameter, lumen diameter, area of transverse section and area of lumen were higher for the second internode than for the first internode, whereas the reverse was reported for stem wall thickness and mechanical layer thickness The results of the principal component analysis and section modulus values revealed similarities between spring spelt Wirtas and Rubinas and between common wheat Kontesa and winter spelt Poeme and Epanis. The number of large vascular bundles varied across the studied varieties. The average number of vascular bundles in common wheat Kontesa was significantly higher than in spring spelt Rubinas and Wirtas and significantly lower than in Polish wheat Pol-3 and winter spelt Epanis and Poeme.

Triticale (× Triticosecale Wittmack) is a hybrid progeny of wheat (Triticum spp.) and rye (Secale cereale L.) and exhibits significant heterosis compared with its parents. Triticale is grown in many countries as a forage crop and has broad application prospects. In this study, conducted in 2015 and 2016 at Gansu, P. R. China, the morphological characteristics of stems, the microstructural features of the second internode from the base, and the chemical components of two triticale lines and two rye lines were compared. This study found that the plant height of triticale was lower than that of rye (P < .01), whereas the triticale internode diameter was larger (P < .05).Compared with values in rye, the diameter of the second internode from the base, thickness of the stem wall, ratio of the length of the second internode to the total length, and the sheath/internode weight ratio were all greater in triticale. Examination of the anatomical structure of the second internode revealed that the basic and vascular tissues of stems of triticale were more developed than those of rye. In addition, cellulose, lignin, neutral detergent fiber, acid detergent fiber, and ash contents of triticale stems were less than those of rye, whereas the triticale soluble sugar content was greater (p < .01). Therefore, we inferred that triticale stems have greater nutritional value, palatability, lodging resistance, and production potential than rye and were suitable for planting and popularizing in alpine pastoral areas.

Identifying quantitative trait loci for lodging‐associated traits in the wheat doubled‐haploid population Avalon × Cadenza

Lodging affects grain quality and grain yield in wheat (Triticum aestivum L.) and is difficult to breed for because its sporadic incidence and laborious protocols to measure lodging traits. Thus, developing molecular markers for these traits can increase selection efficiency in breeding programs. The aim of this article is to identify quantitative trait loci (QTL) associated with stem/anchorage strength and leverage traits (lodging traits) in a doubled-haploid population of UK bread wheat Avalon × Cadenza. Field experiments were conducted in the UK during 2012-2013 near High Mowthorpe and during 2013-2014 at Sutton Bonington. Phenotypic and genetic analysis indicated significant genetic variation for all traits. Stem strength (diameter, wall width, and material strength) and leverage (plant height) traits were highly heritable (0.64-0.95), whereas anchorage strength traits (root plate spread and structural rooting depth) and ear number per plant (leverage trait) were less heritable (0.21-0.33). This study identified 18 QTL for lodging traits and grain yield in chromosomes 1D, 2B, 2D, 3A, 3B, 4A, 4D, 5B, and 6B. Two QTL for stem strength on chromosome 1D and 3B explaining 49.6% of the total phenotypic variation (PVE) are estimated to reduce stem lodging risk and shortening the plant height by 12 cm. One QTL for root plate spread on chromosome 5B explaining 22.4% of the PVE could increase root lodging resistance.
