Breeding of Pisum sativum for yield and yiels stability

Objective

- Obtain new pea varieties characterized by higher yields and improved yield stability.
- Understanding of physiological mechanisms involved in abiotic stresses (such as cold and drought) which affect the seed yield.
- Quantitative and qualitative seed protein yield improvement.
Research has been carried out in order to obtain new varieties of peas characterized by higher yields and improved yield stability. Emphasis has been laid on quality and quantity of seed proteins in relation to ecotypic variability, drought stress and cold tolerance.

It was concluded that carbon dioxide exchange rate was a useful parameter for selecting drought resistant genotypes. The ideotype for drought is a semileafless plant or a plant with reduced stipules. A fairly good correlation was found between in vitro and in vivo responses for cold tolerance but for developing a screening procedure further research is required.
Agronomic trials with randomized blocks - Single seed protein extraction - One and two dimensional gel electrophoresis - Standard techniques for chromosome analysis - In vitro culture.
