Do NERICA rice cultivars express resistance to Striga hermonthica (Del.) Benth. and Striga asiatica (L.) Kuntze under field conditions?
The parasitic weeds Striga asiatica and Striga hermonthica cause high yield losses in rain-fed upland rice in Africa
Abstract
The parasitic weeds Striga asiatica and Striga hermonthica cause high yield losses in rain-fed upland rice in Africa. 2 resistance classes (pre- and post-attachment) and several resistant genotypes have been identified among NERICA (New Rice for Africa) cultivars under laboratory conditions (in vitro) previously. However, little is known about expression of this resistance under field conditions. This study investigated:
-
whether resistance exhibited under controlled conditions would express under representative Striga-infested field conditions
-
whether NERICA cultivars would achieve relatively good grain yields under Striga-infested conditions.
This work arises from the Sustainable Crop production for International Development (SCPRID) programme.
