Wheat leaf rust is an important disease worldwide. Understanding the pathogenic molecular mechanism of Puccinia triticina Eriks. (Pt) and the inconstant toxic region is critical for managing the disease. The present study aimed to analyze the pathogenic divergence between Pt isolates.

The main diseases of wheat (Triticum aestivum L.) in Egypt, causing up to 50% of yield losses. Genetic resistance is the most economic and effective means of reducing yield losses caused by the disease. However, breeding genotypes for disease resistance is a continuous process and plant breeders need to add new effective sources to their breeding materials.

The objectives of this study was to determine the effectiveness of race non-specific and slow-rusting resistance in reducing losses in grain yield and to identify superior recombinants for yield and its component traits having both the genes when exposed to high leaf rust pressure.

Two highly effective genes for leaf rust resistance viz., Lr24, Lr28 were selected for pyramiding in the background of a susceptible but high yielding bread wheat variety DWR 162. The screening against most virulent pathotype of leaf rust 77-5 (121R63-1) indicated that both the genes confer a high degree of seedling resistance.

The most effective way to prevent the occurrence of this disease is to develop genetically resistant cultivars (Mahalingam et al., 2018). Hence, KS-103 was developed to identify a high yielding new variety with tolerant to leaf rust disease.

Powdery mildew and Rust are major diseases of pea of worldwide distribution. Powdery mildew and Rust is an airborne disease. Powdery mildew is a particularly damaging in late sowing or in late maturity varieties. It is caused by Erysisphe pisi. The disease can cause 20-50% yield losses, reducing total yield biomass, number of pods per plant, number of seeds per pod, plant height and number of nodes. The disease also affects green pea quality. Pea rust is characterized by the appearance of two types of symptoms.

In the present investigation, estimates of genetic variability, heritability and genetic advance were assessed for nine different characters in the F3 population derived from four groundnut crosses, viz., CO 7 × VRI Gn 6, TMV 2 × VRI Gn 6, TMV Gn 13 × VRI Gn 6 and VRI 2 × VRI Gn 6. Considering the mean performance, the cross derivative TMV Gn 13 × VRI Gn 6 registered superiority for the characters viz., 100-pod weight (g), 100- kernel weight (g) and sound mature kernel (%).

Groundnut (Arachis hypogaea L.) is an important food and cash crop with multifarious usages for resource poor farmers in Asia and Africa. Groundnut yield is constrained mainly due to two major foliar fungal diseases namely, late leaf spot and rust. The regular incidence of these diseases warrants the development of resistant cultivars and the recent advances in the area of crop genomics offer tools to assist breeding in groundnut.

Biotic and abiotic stresses are major constraints in the production of groundnut. Among biotic stresses apart from bacterial and viral diseases, many fungal diseases are of economic importance. The major fungal diseases are Early leaf spot (Cercospora arachidicola), Late leaf spot (Cercosporidium personatum), Rust (Puccinia arachidis), Botrytis blight (Botrytis cinera), Aflarot/Yellow mould (Aspergillus flavus), Damping off (Pythium spp.

Present study aimed at molecular and phenotypic characterization of F3 population of a cross between leaf rust susceptible but well adapted bread wheat variety DWR 162 and resistant variety PBW 343 carrying highly effective alien genes Lr24 and Lr28 to identify recombinant lines with high productivity and leaf rust resistance. Fifty nine F3 lines with seven checks were evaluated for yield and yield contributing traits in randomized block design (RBD) with two replications.

Groundnut is an important oilseed crop of India and biotic stresses cause heavy yield losses. Development of resistant cultivars is one of the important objectives of the maintenance breeding programmes of groundnut and utilization of molecular markers for identification resistant sources has become a handy tool for plant breeders. Keeping this in view, an experiment was carried to check the resistance source(s) against late leaf spot (LLS) and rust in 30 genotypes under field conditions.

Grass pea (Lathyrus sativus L.) is a valuable resource for potentially durable partial resistance to rust. To gain insight into the resistance mechanism and identify potential resistance genes, we generated the first comprehensive transcriptome assemblies from control and Uromyces pisi inoculated leafs of a susceptible and a partially rust-resistant grass pea genotype by RNA-seq.

Leaf and stripe rusts are two major wheat diseases, causing significant yield losses. The preferred way for protecting wheat from rust pathogens is by introgression of rust resistance traits from wheat-related wild species.

Wheat rusts (Leaf rust, Stem rust and Stripe rust) continue to pose a serious threat by inflicting losses in different parts of world. Leaf rust caused by Puccinia triticina Eriks. is the most common rust disease of wheat (Triticum aestivum L.) and is widespread in India and posses a major threat to the wheat production of the country. Depending upon the severity and duration of infection, the losses may reach up to 50% of the yield. CIMMYT has developed a series of synthetic hexaploid wheat (SHW) by incorporating D genome donor Triticum tauschii in T. durum cultivars.

Wheat production in temperate area is significantly affected by rust diseases, among which stripe (or yellow) rust caused by Puccinia striiformis Westend f. sp. tritici and leaf (or brown) rust caused by Puccinia triticina Eriks. is major threat to production. Non-progenitor Aegilops species with substantial amount of variability for stripe rust resistance genes has been exploited to a limited extent.

Late leaf spot caused by Phaeoisariopsis personata is the most important disease on groundnut worldwide. Although fungicide treatment is effective, it is uneconomical to use because of high cost, hazardous to environment and insensitivity build up in pathogen. The deployment of resistant cultivars is a better option to control LLS disease in groundnut the investigation was undertaken to determine the mode of genetic inheritance of LLS resistance in two F2 and F3 segregating populations of groundnut.

The research study was conducted on impact of training programme on knowledge, perception and attitude of stakeholders towards Bhoochetana programme. The Raichur, Koppal and Bellary districts were purposively selected based on their maximum area under groundnut cultivation. The random sampling procedure is being used to identify 180 beneficiaries. The ex-post –facto research design used for the study. It was observed that 45.56 per cent of the beneficiaries belonged to medium knowledge category followed by low (27.78 %) and high (26.67 %) categories.
