Obviously every project has its own goals and targets. A rootstock needs high resistance to pruning and a fragrant cut rose needs a long vase life. Despite these differences we use a set of basic values, in no particular order these are:

Vigour of growth
Resistance to diseases and pests
High Production

For many companies the so-called environmental paragraph is of growing importance. Governement regulations, but also pressure from the market forces growers and trading companies to think about how and where the products are produced. From the start on PRO has been using organic growing methods. Resistance to diseases and pests has alway been one our prime selection parameters. By avoiding the use of chemicals to cure e.g. mildew we ensure that we breed resistance into our sorts. The results so far are that a number of our products may be suitable for biological growing conditions

Mildew resistance: these roses grew next to each other in a testfield. The difference is obvious and clearly genetic.
