Title (EN) INCREASING HYBRID SEED PRODUCTION THROUGH HIGHER OUTCROSSING RATE IN CYTOPLASMIC MALE STERILE GRAMINEAE PLANTS AND RELATED MATERIALS AND METHODS
(FR) AUGMENTATION DE LA PRODUCTION DE SEMENCES HYBRIDES PAR UN TAUX DE CROISEMENT PLUS ÉLEVÉ CHEZ DES PLANTES GRAMINACÉES STÉRILES CYTOPLASMIQUES ET MATÉRIAUX ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) Methods for increasing hybrid seed production are provided. Increased hybrid seed production is achieved through higher outcrossing rates in cytoplasmic male sterile (CMS) lines of a Gramineae plant. CMS lines having higher outcrossing rates capable of high hybrid seed set are also provided.
(FR) L'invention concerne des procédés pour augmenter la production de semences hybrides. Une production accrue de semences hybrides est obtenue par des taux de croisement plus élevés dans des lignées de mâles stériles cytoplasmiques (CMS) d'une plante graminacée. L'invention concerne également des lignées CMS présentant des taux de croisement plus élevés capables d'une mise à graine hybride élevée.
