Abstract


As for hybridization, the Violet forms were more compatible with the foreign varieties Roma and Makis than the Red forms. The local varieties were also compatible among themselves. The success rate of crossing was on average 50%.The genetic disjunctive generation analysis F2 shows that all characters with discontinuous variation (qualitative: color and shape of the fruit) follow a simple Mendelian genetic determinism. Moreover, heritability (in the broad sense) of some quantitative characters (size, number of flowers, number of fruits and weight of fruits) by the variance decomposition method can reach relatively high values (0.8 to 0.95) for some groups of crossings. The same holds good for heritability in the restricted sense (0.56 to 0.98) for some characters and groups.

Abstract: (french)


Quant à l’hybridation, les formes violettes ont été plus compatibles avec les variétés étrangères Roma et Makis que les formes rouges. Les variétés locales ont été aussi compatibles entre elles. Le taux de réussite de croisement a été en moyenne de 50%.L’analyse génétique de génération disjonctive F2 montre que tous les caractères à variation discontinue (qualitatifs): couleur et forme de fruits suivent un déterminisme génétique mendélien simple. Par ailleurs, l’héritabilité au sens large de quelques caractères quantitatifs (la taille, nombre de fleurs, nombre de fruits et poids de fruits) par la méthode de la décomposition des variances peut atteindre des valeurs relativement élevées (0,8 à 0,95) pour certains groupes de croisements. Il en est de même pour l’héritabilité au sens restreint (0,56 à 0,98) pour certains caractères et pour certains groupes.
