Pyramiding of Adult-Plant Resistance Genes Enhances All-Stage Resistance to Wheat Stripe Rust

Plant Disease, 2023
Stripe rust, caused by Puccinia striiformis f. sp. tritici, is one of the most destructive diseases in wheat production. Pyramiding of adult-plant resistance (APR) genes is a promising strategy to increase durability of resistance. The stripe rust resistance (R) genes Yr18, Yr28, and Yr36 encode different protein families which confer partial ...

Gene action for adult-plant resistance to powdery mildew in wheat

Genome, 1995
Gene action for adult-plant resistance to powdery mildew was studied using generation mean analyses of parents and of F1, F2, and backcross populations derived from a diallel cross of one susceptible and three adult-plant resistant wheat cultivars. Joint scaling tests showed that an additive–dominance model was sufficient to explain the variability in

Rapid phenotyping for adult‐plant resistance to stripe rust in wheat

Plant Breeding, 2011
With 6 figures and 4 tablesAbstractStripe or yellow rust (YR) is a significant problem in wheat crops worldwide. The deployment of adult‐plant resistance (APR) genes in wheat cultivars is considered a sustainable management strategy, as these genes confer partial resistance that is usually non‐race specific.

Inheritance of adult plant resistance to powdery mildew in swedes

Annals of Applied Biology, 1989
SummaryA complete diallel set of crosses, including selfs, was produced from 11 inbred lines of swedes and assessed for adult plant resistance to powdery mildew in a replicated field trial. The plants were inoculated with powdery mildew spores on 23 July 1987. Traces of mildew were visible on 3 August.

Inheritance of adult-plant resistance to Phytophthora capsici in pepper

Euphytica, 1992
Inheritance studies were conducted to determine the genetic basis of adult-plant resistance in pepper (Capsicum annuum L.) to Phytophthora capsici. F1, backcrosses and F2 populations were developed using the resistant parent Criollo de Morellos 334 and susceptible parents Agronomico 10-G and Yolo Wonder.

Inheritance of adult plant resistance to mildew in oats

Annals of Applied Biology, 1986
SUMMARYAdult plant resistance of a durable nature in oat cv. Maldwyn was studied in a cross with the very susceptible cv. Selma, using a replicated F3 population grown under field conditions. Segregation was found to be continuous, with no discrete classes, and a preponderance of segregants showing intermediate values between the two parents indicating

INHERITANCE OF ADULT PLANT RESISTANCE TO POWDERY MILDEW IN SOYBEANS

Canadian Journal of Genetics and Cytology, 1978
In greenhouse tests with Microsphaera diffusa Cke &Pk. on soybeans (Glycine max (L.) Merr.), adult plant resistance was found to be governed by a dominant gene, proposed as Rmd, with the recessive allele, rmd, resulting in susceptibility at all stages.

Seedling and Adult-Plant Resistance to Yellow Rust

2001
Resistance to stripe rust of 56 advanced wheat lines/varieties introduced from International Maize and Wheat Improvement Center (CIMMYT) was evaluated at seedling stage in greenhouse and at adult-plant stage in field. Three pathotypes 6E0A−, 70E16A+, and 134E134A+ were used in greenhouse and pathotype 134E134A+ in field.

Adult Plant and Partial Resistance of Wheat As Kinds of Durable Resistance to Rusts

1993
Reaction of wheat to two types of resistance (adult plant and partial /horizontal) to rusts, has been studied during the last ten years in Bulgaria. Evidence on the existence of typical adult plant resistance (susceptible type of reaction at seedling stage and resistance in the adult stage), is presented.

Histological and cytological characterization of adult plant resistance to wheat stripe rust

Plant Cell Reports, 2012
Wheat cultivar Xingzi 9104 (XZ) possesses adult plant resistance (APR) to stripe rust caused by Puccinia striiformis f. sp. tritici (Pst). In this study, histological and cytological experiments were conducted to elucidate the mechanisms of APR in XZ.
