Resistance to cane and foliar diseases in red raspberry (,) and related species,breeding programme. These are reviewed with a description of the biology of the pathogens involved. Some of them take the form of a mechanical barrier associated with the position and rate of development of suberised periderms. For example, damage to the deep-seated cane polyderm occurs when .

Leaf glucosinolate profiles and their relationship to pest and disease resistance in oilseed rape,sinolates undergo hydrolysis catalysed by the enzyme myrosinase to produce a complex array of products which include volatile isothiocyanates and several compounds with goitrogenic activity. Many of these products have been implicated in the interaction between . and their pests and pathogens and so

Resistance of cowpea and cereals to the parasitic angiosperm ,,fficult and genetically resistant crops are the most feasible and appropriate solution. In cowpea, complete resistance to . has been identified. Breeding for resistance in sorghum has identified varieties with good resistance to . in Africa and India. One variety was also resistant to . in W. Africa

The role of resistance breeding in the integrated control of downy mildew (,) in protected lettuce,ps grown under protection (glass or polythene) in northern Europe. More recently, an as yet genetically uncharacterised resistance factor, R18, has also begun to assume importance. The occurrence of the various combinations of these resistance alleles that exist in commercial cultivars has been dict

,Durable resistance to rice blast disease — environmental influences,af blade and the panicle neck node. Host resistance is the most desirable means of managing blast, especially in developing countries. Rice cultivars with durable blast resistance have been recognized in several production systems. The durable resistance of these cultivars is associated with polygen

Breeders in Europe produced numerous resistant cultivars utilising . while in the USA . was used. The resistance has been effective for over 20 years. However, recently there have been reports of LMV isolates causing unusually severe and sometimes necrotic sym
