IPR 107 - dwarf arabic coffee cultivar with resistance to coffee leaf rust [PDF]

Crop Breeding and Applied Biotechnology, 2013
'IPR 107' was derived from a cross between 'IAPAR 59' and 'Mundo Novo IAC 376-4'. 'IPR 107' is a dwarf medium size plantwith medium precocity in ripening and with complete resistance to rust races in this time. This cultivar presents superior quality and high yield in many coffee regions.

Screening for Resistance to Coffee Leaf Rust

, 2023
AbstractCoffee leaf rust (CLR), caused by Hemileia vastatrix (Hv), is one of the main limiting factors of Arabica coffee production worldwide. Breeding for rust resistance is the most appropriate and sustainable strategy to control CLR. The characterization of coffee resistance to Hv, initiated in the 1930s in India, expanded with the creation of ...

Correlation Between Secondary Metabolites of Leaf and the Resistance to Leaf Rust (Hemileia vastatrix) on Several Arabica Coffee Clones

Ilmu Pertanian (Agricultural Science), 2019
Indicator of coffee resistance to leaf rust attack (Hemileia vastatrix) is needed to select superior coffee plants resistant to biotic stress. This study aims to find the relationship between the content of secondary metabolites and the intensity of leaf

Genotypic and Phenotypic Correlations between Leaf-Rust Disease and Leaf Morphology and its Ratio in Arabica Coffee

Jurnal Ilmu Pertanian Indonesia, 2020
Selection parameter in coffee breeding for leaf rust (Hemeleia vastatrix) resistance is very important. Breeders used leaf-rust severity and leaf-rust incidence as parameters of direct selection.

The genome sequence and effector complement of the flax rust pathogen Melampsora lini [PDF]

, 2016
Rust fungi cause serious yield reductions on crops, including wheat, barley, soybean, coffee, and represent real threats to global food security. Of these fungi, the flax rust pathogen Melampsora lini has been developed most extensively over the past 80 ...

Leaf surface microbiota transplantation confers resistance to coffee leaf rust in susceptible Coffea arabica. [PDF]

FEMS Microbiol Ecol
Abstract Coffee leaf rust, caused by the fungus Hemileia vastatrix, has become a major concern for coffee-producing countries. Additionally, there has been an increase in the resistance of certain races of the fungus to fungicides and breeding cultivars, making producers use alternative control methods.

Polyphenol Content and Enhancing Plant resistance of Lowland Arabica Coffee [PDF]

E3S Web of Conferences, 2020
The production of arabica coffee in Indonesia is still low because of leaf rust disease suppression caused by Hemileia vastatrix. Basically, it can produce well in the overlapping zone (1000-1500 masl).

RoCoLe: A robusta coffee leaf images dataset for evaluation of machine learning based methods in plant diseases recognition

Data in Brief, 2019
In this article we introduce a robusta coffee leaf images dataset called RoCoLe. The dataset contains 1560 leaf images with visible red mites and spots (denoting coffee leaf rust presence) for infection cases and images without such structures for ...
