Opis:: Mechanically harvested crops must be erect (lodging resistant) to facilitate harvest. Stem lodging changes canopy structure, increases disease pressure, reduces yield, and reduces harvest efficiency in pea. A number of studies have examined the traits that cause lodging susceptibility, but the relative impact of each trait is difficult to determine. A great need exists in pea breeding to develop a working model to explain lodging resistance. This study used the flexure formula to predict the amount of lodging variation explained by some of the major traits. Datasets from pea indicate that the percent variation explained by this lodging model is ~58%, and this model can be used to predict the relative impact of an increase in load, height, stem diameter, stem wall thickness, or yield on lodging susceptibility. This study indicates that plant height is strongly correlated with lodging susceptibility, but stem diameter is positively correlated with lodging resistance. Stem wall thickness appears to have no major effect on lodging resistance, which has not been previously reported in pea. Any doubling in plant height would also double the amount of stem material, but stem stress is expected to increase fourfold. A doubling in stem diameter is expected to increase the amount of stem material by fourfold and decrease stem stress by eightfold. The results of this study indicate that plant breeders should focus on increasing basal stem diameter to increase lodging resistance.

Opis:: The results of plant breeding trials with populations of fodder pea strains and broad bean hybrids were the basis of consideration on the interrelationship between some traits - the yield structure elements. Developed by Eaton, a relatively new method of yield component analysis called the two-dimensional partitioning method (TDP) was applied to analyse the data. The method, which combines multiple regression and ANOVA, allows for concise tabular presentation and simple interpretation of the distribution of traits in one direction and the sources of variance according to ANOVA model in the other direction. Additionally, the interpretation of the results was supported by such standard statistical techniques as ANOVA, simple and multiple regression and path analysis. The main components of pea yielding were plant height and the number of pods per plant. Among the analysed characters of broad bean the number of nodes with pods on the main stem, which turned out to be the determinant of broad bean yielding, might be strongly affected by environmental conditions. The number of nodes with pods might be considered a selecting character of high potential yielding of broad bean genotypes.
