Course: Vegetable breeding for resistance

Penelope Bebeli
Eleni Tani

The course describes breeding plants for biotic and abiotic stresses with special emphasis on vegetable breeding. The topics covered include: Resistance to diseases and pests; Qualitative and quantitative aspects of resistance; Mechanisms of resistance; Breeding strategies towards resistant vegetable cultivars; Resistance to abiotic stress factors; Plant abiotic stress response; Traits for abiotic stress breeding; Classical approaches and  genomics tools for abiotic stress breeding in vegetables.

Course description:

1.   Introduction to vegetable breeding and plant resistance.

2. Plant defense and principles of plant resistance: plant defense, resistance (definition, types of plant resistance), host-parasite interaction (expression, understanding, reaction), factors affecting plant resistance expression. Breeding strategy and methods used in building up resistance. Genetic engineering/ biotechnology and production of resistant lines and varieties.

3.   Vegetable breeding for biotic stresses: asexually propagated vegetables (artichoke, garlic, some species of onion etc.), self-pollinated crops (tomato, lettuce, green pepper etc.), cross-pollinated crops (cucumber, courgette, melon, watermelon, cauliflower, cabbage, kohlrabi, onion etc.

4. Plant responces to abiotic stresses. Drought. Salt stress. Extreme temperatures. Anoxia. Breeding vegetables for resistance to abiotic stresses.
