Growth and resistance of F1: the results of kenaf interspecific crosses to root-knot nematode (Meloidogyne incognita)

Abstract

The aim of interspecific crosses between kenaf and close relatives is to obtain superior varieties of kenaf resistant to nematodes. This study aims to determine F1 inter-specific kenaf crosses resistance compared to its parents toM. incognita infection. The evaluation of kenaf genotype resistance was determined by gall index. The growth of F1 genotypes resulted from crossing SRRH023 x Kin2, and crosses of Kal II x Kin2 showed that it was higher than his close relative parents and smaller than the kenaf and M. incognita resistant. The F1 of kenaf inter-specific crosses with its close relatives was resistant to M. incognita nematodes.
