Unfortunately, for some pathogens and pests, there genetic resistance in pea (Pisum sativum ssp.
sativum)
germplasm and cultivars is scarce.
In occasions, we can exploit them for related
P. sativum
ssp.
germplasm, or even from the most distant
P. fulvum. Examples of the breeding activities performed at
CSIC-Cordoba will be mentioned. Germplasm collections of
Pisum
have been throroughtly screened for
resistance to ascochyta blight, powdery mildew, rust, broomrape, and more recently fusarium wilt, aphid
and weevil, yielding the identification of valuable sources of resistance that are being introduced in our
breeding program. Inheritance of some
of the identified resistances has been studied and underlaying
mechanisms characterized. As an example, a new gene (Er3) for powdery mildew resistance was identified
in P. fulvum and introduced in pea, with a resistant cultivar being released. Similarly, the first two
broomrape resistant cultivars are now being realeased. Breeding for ascochyta, rust, aphid and weevil
resistance is in progress.
