Genetic characterization of leaf and stripe rust resistance in the Brazilian wheat cultivar toropi. Repositório Alice
ROSA, S. B.; ZANELLA, C. M.; HIEBERT, C. W.; BRULE-BABEL, A. L.; RANDHAWA, H. S.; SHORTER, S.; BOYD, L. A.; MCCALLUM, B. D.; BRAMMER, S. P..
Leaf and stripe rust are major threats to wheat production worldwide. The effective, multiple rust resistances present in the Brazilian cultivar Toropi makes it an excellent choice for a genetic study of rust resistance. Testing of DNA from different seed lots of Toropi with 2,194 polymorphic 90K iSelect single nucleotide polymorphism markers identified significant genetic divergence, with as much as 35% dissimilarity between seed lots. As a result, further work was conducted with a single plant line derived from Toropi variant Toropi-6.4. A double haploid population with 168 lines derived from the cross Toropi-6.4 × Thatcher was phenotyped over multiple years and locations in Canada, New Zealand, and Kenya, with a total of seven field trials undertaken...

Mejoramiento genético del jitomate riñón (Lycopersicon esculentum Mill.) por resistencia horizontal a patógenos localmente importantes en Yautepec, Morelos, México Colegio de Postgraduados
Guzmán Moreno, Marco Antonio.
Se realizaron cruzas a partir de accesiones de jitomate riñón, de Hidalgo, Puebla y Tabasco, con resistencia de tipo cuantitativa a Fusarium oxysporum, que fungieron como receptores, con un genotipo comercial de tipo saladet (Variedad. Río Grande), que fue el donador de polen, para obtener híbridos resistentes y con frutos de forma redonda y lisa. También se realizó selección a partir de jitomates riñón por forma redonda, lisa y con resistencia a enfermedades. Se realizó el avance generacional de los híbridos así como de los genotipos seleccionados, posteriormente se sembraron en campo las cruzas en F2, genotipos seleccionados, genotipos criollos no seleccionados (testigo) y el testigo general (Río Grande), para conocer su reacción frente a los patógenos...

New sources of partial resistance to bacterial spot race T2 in processing tomatoes Horticultura Brasileira
Berrueta,María C; Giménez,Gustavo; Galván,Guillermo A; Borges,Alejandra.
ABSTRACT Bacterial leaf spot of tomato is caused by four Xanthomonas species, among which Xanthomonas vesicatoria race T2 predominates in Uruguay. Difficulties in integrated disease management and the rapid spread of the pathogen led to investigations of genetic resistance. This study aimed to identify resistance sources to bacterial leaf spot race T2 in tomato for processing. Twelve genotypes were evaluated under field conditions in 2010 and 2011. Plants were spray-inoculated with a suspension of bacteria (108 cfu/mL) 15 days after transplantation. Incubation period, disease severity on leaves, and the percentage of fruits with symptoms at harvest were determined. The incubation period did not differ among the genotypes. The genotype 'Hawaii 7981' had the...

Resistance to leaf rust in coffee carrying S H3 gene and others S H genes BABT
Sera,Gustavo Hiroshi; Sera,Tumoru; Ito,Dhalton Shiguer; Azevedo,José Alves de; Mata,João Siqueira da; Dói,Deisy Saori; Ribeiro Filho,Claudionor; Kanayama,Fabio Seidi.
The aim of this work was to evaluate the resistance to rust in coffee carrying S H3 gene and other S H genes. Twenty one CIFC’s coffee trees with several resistance genes S H were evaluated in field conditions. All the evaluated coffees carrying Sh3 gene presented resistance to the rust. It was possible that rust races with the virulence gene v3 in the Paraná State didn’t exist. The S H3 gene in combination with genes S H5, S H6, S H7, S H8, S H9 and S H? would be very important to obtain cultivars with more durable resistance to the rust.

Bacterial blight (BB), caused by Xanthomonas oryzae pv. oryzae (Xoo), is one of the most serious diseases of rice in all major rice-growing areas of Thailand. The most effective approach to control BB is the use of resistant varieties which is economically feasible, an environmental-friendly control method and easy for farmers to handle. However, the selection pressure from the usage of resistant cultivars may result in mutation of the pathogen population to overcome the resistance genes. A feasible method to solve this problem is by pyramiding multiple resistance genes, which are board spectrum, into susceptible rice varieties. The aims of this research were to identify the effectiveness of board spectrum BB resistance genes and to better understand the...
