“…These findings are supported by previous researchers, namely that lodging is a highly variable trait dependent on environmental conditions (Erskine and Goodrich 1988), and that plant population density may increase lodging (Ibrahim et al 1993). In progenitors to modern lentil cultivars, Whitehead et al (1998a, b) found that modern cultivars were larger plants that contained less lignin compared with their brittle progenitors.…”

. 2006. Canopy growth and biomass partitioning to yield in short-season lentil. Can. J. Plant Sci. 86: 109-119. Lentil (Lens culinaris L.) cultivars in the large green market class in Western Canada have lateseason bushy growth, low harvest index (HI), and lodge readily. The aim of this study was to compare a range of genotypes for canopy traits such as rapid growth, light interception, HI, lodging, and yield. Four stiff-stem unadapted genotypes varying in leaf size and canopy openness were compared with two large green market class and other locally adapted cultivars at three population densities in the field in 2001 and 2002. Canopy measurements included biomass and light interception at weekly intervals, lodging score, end of season HI and yield. Adapted cultivars had high biomass (525 to 700 g m -2 ), high seed yield (96 to 130 g m -2 ), high maximum light interception (61 to 80%), high final branch number (17 to 19), and greatest overall plant height (0.3 to 0.44 m), but large green cultivars were prone to lodging. Unadapted genotypes produced less biomass and lodged the least. Genotypes that accumulated most above-ground biomass yielded the highest, grew the tallest, branched the most, but lodged the most. Unadapted genotypes FLIP 2000-7L (tallest, highest yielding of the unadapted types) and FLIP 96-7L (most lodging resistant (2001) and most brittle stemmed (2002) were promising parents for improving lodging resistance, on the basis of lodging resistance and yield or stem stiffness, respectively. CDC Milestone had the best canopy characteristics of moderate biomass and high harvest index for Western Canada.

“…The accumulated evidence in different crops has suggested that resistance to lodging is associated with genotype (Ibrahim et al 1993;Pu et al 2000;Inoue et al 2004;Huang et al 2008). Lodging occurs when strong winds are accompanied by rainfall during grain filling stage, which often occurs during the growing seasons for foxtail millet in northern China.…”

“…Various methods and traits have been used in the field evaluation of lodging in cereal crops (Jezowski 1981;Crook and Ennos 1994;Pu et al 2000;Wang and Du 2001;Berry et al 2003b;Sakata et al 2003), as well as other crops (Ibrahim et al 1993;Huang et al 2008). However, a protocol is not available for screening foxtail millet genotypes resistant to lodging.…”

Lodging results in serious yield and quality reductions in foxtail millet (Setaria italica). Among summer crops, foxtail millet is a high density and soft stalked crop that is prone to lodging. Field selection for lodging resistance is difficult because the occurrence of lodging depends on the environmental conditions. A practical method for the evaluation of lodging is not available for foxtail millet, so an understanding of lodging-associated traits and identifying a suitable method to assess lodging are essential to select for lodging resistance and to predict the risk of lodging in a cultivar. In the present study, six stem and root traits associated with lodging was measured in the field and lodging coefficients were determined to evaluate lodging resistance in landrace and improved cultivars. Based on the results of correlation analysis, lodging coefficient is a suitable indicator for field selection for lodging resistance in both classes of cultivars tested for breeding purpose. Statistical analyses demonstrated that lodging was associated with stem quality rather than plant height and internode length at the stem base. The most important trait that directly impacted on lodging coefficient was mechanical strength of the stem and plant height in the landraces, while the weights of the above-and underground tissues, in combination with mechanical strength of the stem, were the most important contributors to lodging coefficient in the improved cultivars.

“…For the adapted group, CDC Grandora had the widest diameter, which was significantly greater than CDC Plata and CDC Milestone, and finally Crimson Stem diameter was significantly different for plant population treatments, with a decrease in stem diameter as the plant population increased. Board (2001) and Ibrahim et al (1993) reported similar results where stem diameter was found to decrease as plant populations moved from low to high in soybean and lentil, respectively. Thinner stems at high population were associated with increased lodging in both crops.…”

Ball, R. A., Hanlan, T. G. and Vandenberg, A. 2006. Stem and canopy attributes that affect lodging resistance in lentil. Can. J. Plant Sci. 86: 71-81. Many lentil (Lens culinaris L.) cultivars currently grown in Western Canada are susceptible to lodging. The objective was to determine if plant traits associated with lodging but independent of environmental influences could be used for indirect selection of lodging resistance. For a range of canopy variation, eight genotypes were grown at three plant population densities in the field in 2001 and 2002 at five locations. Four unadapted genotypes (designated FLIP), varying in plant profile and stem stiffness, were compared with locally adapted cultivars. Lodging is a complex trait and was influenced by both genetic differences among the genotypes and environmental conditions. Large green market class cultivars had weak stems and lodged easily. As the canopy's ability to recover from crushing increased, lodging increased due to greater plant biomass. The greater the fiber content in the plant stems, the more biomass and more lodging occurred. Genotypic ranking of stem diameter was consistent across locations, and stem diameter may be used to indirectly select for lodging resistance. From regression analysis, stem diameter and lodging were described by branch number, recovery from canopy crushing, plant density, height, stem fiber content and lignin content; branch number, plant density and plant height were the most influential terms. For screening lodging resistance in crosses made from a lodging resistant genotype and a highly lodging susceptible genotype, selection of progeny with the smallest stem diameter should be the most lodging resistant, although yields will be reduced. Selection procedures would involve seeking large diameter stems but with similar stem traits of the small-stemmed FLIP lines. La verse s'accroît avec la capacité du couvert de se remettre de l'écrasement en raison de la plus grande biomasse. Plus la tige des plants est fibreuse, plus la biomasse est importante, donc la verse également. Le classement des génotypes en fonction du diamètre de la tige reste le même d'un endroit à l'autre, aussi pourrait-on utiliser ce caractère pour sélectionner indirectement la résistance à la verse. S'appuyant sur l'analyse de régression, les auteurs décrivent le diamètre de la tige et le degré de verse d'après le nombre de ramifications, le rétablissement après écrasement du couvert, la densité de semis, la hauteur ainsi que la concentration de cellulose et de lignine dans la tige. Le nombre de ramifications, la densité de semis et la hauteur sont les paramètres qui exercent la plus forte influence. Quand on cherche à déceler les hybrides résistants issus du croisement entre un génotype résistant et un autre très sensible, la progéniture présentant les tiges du plus petit diamètre devrait être aussi celle qui résiste le mieux à la verse, mais on assistera parallèlement à une diminution du rendement. Les méthodes de sélection devraient inclure la recherche de ...
