Abstract

Spring bread wheat (Triticum aestivum L.) is one of the main food crops grown in Western Siberia. Wheat lodging causes significant damage to yields, reduces protein content and affects the technological properties of grain and flour. The paper presents the results of studying anatomical and morphological features of spring soft wheat and their correlation with resistance to lodging. Lodging resistance of eleven spring soft wheat varieties was examined in the experimental fields of SibNIIRS, a branch of the Institute of Cytology and Genetics SB RAS during 2019–2020. High resistance to lodging was determined in seven out of 11 varieties (‘Triso’, ‘Novosibirskaya 29’, ‘Novosibirskaya 16’, ‘Bel’, ‘Velut’, ‘Chernyava 13’, and ‘Novosibirskaya 15’) in both field tests. Lodging resistance in other genotypes varied from low to medium. The following anatomical and morphological features of the stem were examined: plant height, the diameter of upper and lower internodes, the thickness of culms, the thickness of primary cortices, the diameter of medullary lacunas, the number of vascular bundles of upper and lower internodes and their diameter. Principal component analysis indicated that the variability of anatomical and morphological features was determined by three principal components, which together constituted 68.39 % of the total variance. The first component determining 44.25 % of the variance included the following anatomical features: the diameter of internodes, the thickness of primary cortices, the diameter of medullary lacunas, the thickness of culms, and the number of vascular bundles. These traits should be taken into account in selection for lodging resistance
