Structural Analysis of Some Spring Wheat Genotypes Having Genetic Resistance to Puccinia Recondita

Year: 2025

Type: article

Abstract: An assessment of the development of the morphological structure of the main shoot of introgressive varieties and lines of the Saratov spring soft wheat was carried out on the L 503, L 503 Lr19+Lr26, L 505, L 505 656/11, Prokhorovka, SE 2, Dobrynya, Dobrynya lr19 + lr37, Belyanka, Favorite, Voevoda, Lebedushka, Swan, Alexandrite varieties. The total number of tillers ranged from 1.47 to 2.8 of which the productive ones ranged from 66 to 87%. The lengths of the ears reached 71.4 to 87.8 mm, the spikelets numbered 13.9 to 15.83 pieces, while the number of grains of the ear ranged from 26.7 to 40.83 pieces. The weight of the grain varied from 27.4 mg to 34.8 mg. Only the SE 2 variety was distinguished by the imbalance of morphogenesis in terms of ear productivity elements. The morphogenetic productivity index in the 2023 growing season was between 2.63 to 4.3 for the spikelets, 1.87 to 3.3 for the number of grains, and 3.23 to 3.97 for the weight of the grains
