Abstract

The groundnut variety ICG 2271 is the most resistant to thrips In our conditions. Despite the existence of some differences between types, the number of thrips per flower In the cowpea is negatively correlated with the total number of flowers present per plant, the rate of pod formation, the internode and pod length, the pod number per plant and grain yield. It Is positively correlated with the percentage of flowers shed per plant.

In the pigeonpea, the characters linked to the number of thrips per flower vary with varieties. However, days to maturity and height at the same stage are more consistent.

The days to 50% flowering are positively correlated with the number of thrips per flower In the cowpea and pigeonpea.

Résumé

La variété d'aracbide ICG 2271 est la plus résistante aux thrips dans noe conditions. Malgré l'existence de certaines différences entre types, te nombre de thrips par fleur chez le niébé est corrélé négativement au nom be total de fleurs présentes par plant, au taux de formation des gousses, à la longueur de l'internode et de la gousse, au nombre de gousses par plant et au rendement. II est corrélé positivement au pourcentage de fleurs tombées par plant.

Chez le pois d'Angole, les caractères liés au nombre de thrips par fleur varient selon les variétés. Néanmoins le nombre de jours à la maturité et le hauteur à cette même phase sont les plus consistants.

Le nombre de jours à 50% de floraison est corrélé positivement au nombre de thrips par fleur chez le niébé et le pois d'Angole.
