Infestation of soft spring wheat plants depends on the growth stage and weather conditions growing season. Plants have highest resistance to brown rust in tillering stage. Brown developed 2014 throughout The lowest infestation intensity was during – booting stage, which did not change from experiment variant 5.0 %. spread 10 %, 40 assessed 8 points.

been widely used to characterize foliar disease resistance (Jeger and Viljanen-Rollinson, 2001) because it Slow leaf-rusting resistance in wheat (Triticum aestivum L) is gainreflects both severity and rate of disease development ing acceptance as a breeding objective because of its durability in comparison with race-specific resistance. CI 13227 was previously (Wilcoxson et al., 1975). IR and I...

With the advancement of QTL mapping strategies, the traditional approaches for the identification of genes and their effects responsible for trait expression are gradually losing significance. The phenotypic data for heading days, plant height, peduncle length, number of tillers and stripe rust was recorded on 150 recombinant inbred line (RIL) population developed from a barley cross of ‘Stepto...

Grass genomes differ greatly in chromosome number, ploidy level, and size. Despite these differences, very good conservation of the marker order (collinearity) was found at the genetic map level between the different grass genomes. Collinearity is particularly good between rice chromosome 1 and the group 3 chromosomes in the Triticeae. We have used this collinearity to saturate the leaf rust re...

Fig rust, caused by Cerotelium fici, was first recorded in South Africa 1927. Recent observations have revealed high incidence of rust and untimely defoliation fig trees (Ficus carica) residential gardens commercial orchards. Using phylogenetic analysis, the causal organism a isolate (PREM63073) collected 2020 confirmed as Phakopsora nishidana. Inoculation microscope studies showed that mulberr...
