Seventy three germplasm of field pea were tested under glasshouse and field condition against rust disease caused by Uromyces viciae fabae (Pers.) de Bary. Among screened germplasms, 30 susceptible, 40 highly susceptible and 3 belonged to moderately resistance group. The susceptible germplasm showed leaf area with symptoms (LAS) ranged from 30 to 65% with area under disease progressive curve (AUDPC) values from 77.5 to 1290 and apparent infection rate from 0.0134 to 0.1698 and highly susceptible germplasm showed LAS ranged from 60 to 95% with AUDPC values ranged from 1075 to 2179. Apparent infection rate ranged from 0.0616 to 0.6950 while moderately resistance germplasm showed LAS ranged from 20 to 24% with AUDPC values ranged from 350 to 438 and apparent infection rate ranged from 0.1180 to 0.1198 in field as well as glasshouse conditions. The moderate resistance germplasm JPF 99025, KPMR 615 and KPMR 551showed lowest LAS, AUDPC value and apparent infection rate, hence, these germplasms could be used in breeding programme.

Pectic Substances

The content of pectic substances (soluble pectins and fraction of protopectins) and calcium (free and bound) in field pea (<i>Pisum arvense</i> L.) leaves and stems during budding and flowering in field conditions was determined. In this experiment Gesagard 50 (S. A. - 50% prometryne) was applied to the soil in a weed control dose (2 kg/ha). An insignificant decrease of the content of protopectins and total pectins in leaves of the investigated plants (about 3-7% in relation to control) after application of this herbicide was noted, hut analogous changes in all years of the experiment were not observed in field pea stems. The influence of prometryne on the distribution of pectic substances in above-ground parts of the field pea and the degree of protopectins methylation were not corroborated. Neither did the total calcium content in the investigated plants change after application ofthe herbicide. These results show that application of Gesagard 50 in a weed control dose (2 kg/ha) in cultivation of field pea does not evoke changes in the investigated components content which might be of significance in the growth and development of plant cells and immunity reactions of plants.

Extensive Evaluation

Rust disease is an important problem for leek cultivation worldwide. It reduces market value and in extreme cases destroys the entire harvest. Farmers have to resort to periodical full-field fungicide applications to prevent the spread of disease, once every 1 to 5 weeks, depending on the cultivar and weather conditions. This implies an economic cost for the farmer and an environmental cost for society. Hyperspectral sensors have been extensively used to address this issue in research, but their application in the field has been limited to a relatively low number of crops, excluding leek, due to the high investment costs and complex data gathering and analysis associated with these sensors. To fill this gap, a methodology was developed for detecting leek rust disease using hyperspectral proximal sensing data combined with supervised machine learning. First, a hyperspectral library was constructed containing 43,416 spectra with a waveband range of 400–1000 nm, measured under field conditions. Then, an extensive evaluation of 11 common classifiers was performed using the scikit-learn machine learning library in Python, combined with a variety of wavelength selection techniques and preprocessing strategies. The best performing model was a (linear) logistic regression model that was able to correctly classify rust disease with an accuracy of 98.14 %, using reflectance values at 556 and 661 nm, combined with the value of the first derivative at 511 nm. This model was used to classify unlabelled hyperspectral images, confirming that the model was able to accurately classify leek rust disease symptoms. It can be concluded that the results in this work are an important step towards the mapping of leek rust disease, and that future research is needed to overcome certain challenges before variable rate fungicide applications can be adopted against leek rust disease.

Pectic Substances

The content of reducing sugars, soluble pectins, protopectins and free and bound calcium in above-ground parts of field pea (<i>Pisum arvense</i> L.) during budding and flowering in field conditions was determined. In this experiment different mineral fertilization and Afalon (linuron) were used. Afalon was applied to the soil in weed control dose (1 kg/ha A.S.). The significant influence of linuron and the level of fertilization on the content of determined components in investigated material was not corroborated. The content of pectic substances, first of all, was dependend on phase of vegetation. The differences in the content of calcium were related to distribution in above-ground parts of investigated plants. The tendency to reduction of the content of reducing sugars after application of linuron was observed only during budding of field pea. The received resultes show that linuron used in weed control doses has not evoked unprofitable changes in the content of investigated components of cell wall which they could the significance in the growth and development and in some immunity reactions of plants.

Adult plant resistance in wheat is an achievement of the breeding objective because of its durability in comparison with race-specific resistance. Partial resistance to wheat stripe rust disease was evaluated under greenhouse and field conditions during the period from 2016 to 2021. Misr 3, Sakha 95, and Giza 171 were the highest effective wheat genotypes against Puccinia striiformis f. sp. tritici races. Under greenhouse genotypes, Sakha 94, Giza 168, and Shandaweel1 were moderately susceptible, had the longest latent period and lowest values of the length of stripes and infection frequency at the adult stage. Partial resistance levels under field conditions were assessed, genotypes Sakha 94, Giza 168, and Shandaweel1 exhibited partial resistance against the disease. Leaf tip necrosis (LTN) was noted positively in three genotypes Sakha 94, Sakha 95, and Shandaweel1. Molecular analyses of Yr18 were performed for csLV34, cssfr1, and cssfr2 markers. Only Sakha 94 and Shandaweel1 proved to carry the Yr18 resistance allele at both phenotypic and genotypic levels. Scanning electron microscopy (SEM) observed that the susceptible genotypes were colonized extensively on leaves, but on the slow-rusting genotype, the pustules were much less in number, diminutive, and poorly sporulation, which is similar to the pustule of NIL Jupateco73 ‘R’.
