BREEDING FOR RESISTANCE TO ROSETTE (DOUBLE BLOSSOM) DISEASE IN BLACKBERRY

Breeding Cattle for Genetic Resistance to Disease

Evaluation of Post-Harvest Disease Resistance in Blackberry Cultivars

Seventeen blackberry cultivars were evaluated for postharvest fruit-rot resistance in June and July, 2003. Fully mature, undamaged berries were harvested on two dates for each genotype at the University of Arkansas Fruit Substation, Clarksville. After transporting in chilled coolers to the Plant Pathology Department in Fayetteville, two replications of 10 berries of each genotype were placed in...

Breeding for Salt-Resistance Using Transgressive Segregation in Spring Wheat

Hybrid populations (F3) derived from cross between four moderate salt-resistant spring wheat (Triticum aestivum L.) were assessed for transgressive segregation of salt-tolerant genotypes allowing germination and emergence at 350 mM NaCl for 30 days. The achieved Selection intensity was the order of 0.24-0.27 in these segregation populations (22-25 seedlings from 9000 seeds). Assessment of trans...

Novel genes for disease-resistance breeding.

Plant disease control is entering an exciting period during which transgenic plants showing improved resistance to pathogenic viruses, bacteria, fungi and insects are being developed. This review summarizes the first successful attempts to engineer fungal resistance in crops, and highlights two promising approaches. Biotechnology provides the promise of new integrated disease management strateg...
