“…Lodging is a constraint in many crops, including finger and foxtail millets mainly due to soft stalk that are prone to lodging and crop management and environmental factors. In foxtail millet, Tian et al (2010) suggested lodging coefficient as a suitable indicator for field selection for lodging resistance. Foxtail millet landraces and improved varieties that resist lodging have been reported from China (Table 7.3).…”

“…Numerous studies have reported variation in lodging resistance among genotypes of cereal crops, such as wheat (Easson et al 1993;Crook & Ennos 1994;Berry et al 2003a, b;Kelbert et al 2004a, b), barley (Hordeum vulgare L.) (Wang & Du 2001) and rice (Oryza sativa L.) (Ookawa & Ishihara 1992;Kashiwagi et al 2010), as well as foxtail millet (Tian et al 2010). In addition to genetic factors, damage from insects and/or diseases, together with rain and wind, can also increase the severity of stem-based lodging.…”

“…A cultivar with a low LC is expected to have reduced risk of lodging. The use of a LC to determine variation in stem-based lodging in cultivars and landraces of foxtail millet has been demonstrated: Tian et al (2010) found that stem-based lodging of foxtail millet was associated with stem-breaking strength (SBS), SFM (mechanical strength of stem) and the BM of above-ground parts and the roots. Plant height and internode length were closely related to stembased lodging in the landraces, but not in the modern improved cultivars.…”

Lodging can be an important factor in limiting yield and quality of summer foxtail millet [Setaria italica (L.) P. Beauv.]. Although lodging resistance varies among different genotypes, direct selection for lodging resistance is difficult because of its sporadic occurrence in the field and inconsistency between years. A 2-year-field study was conducted with 35 summer foxtail millet cultivars or advanced breeding lines to determine the association between lodging resistance and culm morphology, anatomy and chemical composition. Path analyses indicated that stem-breaking strength had the most important effect on the lodging coefficient. The breaking strength of stem was associated with specific morphological properties of the culm, such as greater culm diameter and most importantly culm wall thickness. Width of sclerenchyma tissue, and the number and sheath width of the large vascular bundles were the major anatomical properties that influenced stem-breaking strength. The cellulose and lignin compositions of the culm had different effects on stem-breaking strength. Cultivars with smaller lodging coefficients contained higher levels of cellulose, but lower levels of lignin than the cultivars that were more prone to lodging. The findings from the present study provide useful information on lodging-associated traits in the culm that can be used as indicators for the improvement of lodging resistance in foxtail millet.

“…Foxtail millet is also a major crop in the arid and semiarid region of India and is cultivated for bird feeding and forage production in Europe and North America. Among grass crops, foxtail millet belongs to the high‐density cultivated and soft‐stalked crops that are prone to lodging, which results in serious yield and quality reductions (Tian et al, 2010; Qian et al, 2012).…”

Characterization and Fine Mapping of SiDWARF2 (D2) in Foxtail Millet

et al. 2016

Elongation of grass internodes determines the plant height and underlies the grain yield of grass crop species, by enhancing of lodging resistance in elite cultivars. Foxtail millet [Setaria italica (L.) P. Beauv.] is an ancient cereal crop that served as a staple food during early civilization in China and is still grown widely across South and East Asia, Europe, and Africa. In this study, a foxtail millet dwarf mutant (Sidwarf2), derived from ‘Yugu1’, was characterized. In the dwarf mutant, significantly reduced cell lengths caused the observed shorter internodes. Gibberellin sensitivity analyses suggested that the height of the mutant could be restored under out spraying of gibberellic acid (GA3). In both the wild‐type and the mutant, endogenous levels of GA3 in elongated internodes stayed the same, while the abscisic acid (ABA) content of the dwarf mutant was greatly elevated. The dwarf gene (D2) was finally mapped on chromosome 3 and located to a genome region spanning 52.7 kb using combined bulked segregation analysis and map‐based approaches. Twelve transcripts were annotated in the target region and a cytochrome P450 encoding gene was deduced to be the candidate gene of D2. This study highlighted the potential of fast‐mapping‐favorable loci in foxtail millet, which will aid molecular selection and modification of foxtail millet in the future.
