Five Multiple-virus-resistant Common Bean Breeding Lines

Tomato Breeding Lines Resistant and Tolerant to Tomato Yellow Leaf Curl Virus Issued from Lycopersicon hirsutum.

ABSTRACT Two tomato yellow leaf curl virus (TYLCV)-resistant plants from accessions LA1777 and LA386 of the wild tomato species Lycopersicon hirsutum have been crossed. The resulting resistant F1 plants were crossed with the domesticated tomato L. esculentum, and a series of selfing was performed. At each generation, individuals were selected for resistance (no symptoms and undetectable viral D...

distribution study of resistant genes to bean common mosaic virus in bean genotypes (phaseolus vulgaris l.) using scar molecular markers

in order to determine resistance genetically potential of some bean genotypes to bean common mosaic virus, two separated experiments in randomized complete block design with 25 genotypes and three replications was conducted in iau shiraz branch. the first experiment and the second one were performed in normal and bcmv infected conditions, respectively. plants were inoculated in cotyledon leaf a...

Sequence Analysis of Expressed cDNA of Bean Common Mosaic Virus RU1 Isolate

RNAi-mediated resistance to Bean golden mosaic virus in genetically engineered common bean (Phaseolus vulgaris).

Bean golden mosaic virus (BGMV) is transmitted by the whitefly Bemisia tabaci in a persistent, circulative manner, causing the golden mosaic of common bean (Phaseolus vulgaris L.). The characteristic symptoms are yellow-green mosaic of leaves, stunted growth, or distorted pods. The disease is the largest constraint to bean production in Latin America and causes severe yield losses (40 to 100%)....

Seventy-five Years of Breeding Dry Bean of the Western USA

A periodic comparison of cultivars is essential to assess selection gains, determine deficiencies, define objectives, and set breeding priorities. Our objective was to assess the progress, or lack thereof, achieved in improving yield, plant type, maturity, and resistance to major bacterial, fungal, and viral diseases of dry bean of the western USA from 1918 to 1998. Twentyfive great northern, p...
