Abstract: | Summary Through recurrent selection and progeny testing, five bitter almond genotypes have indicated dominance of resistance for the root-knot nematode Meloidogyne javanica.All progenies from reciprocal crosses of resistant bitter almonds x susceptible sweet almonds were found completely resistant in four out of five bitter almond progenies. One selection showed near complete dominance of resistance. Progenies of resistant peach x susceptible almond cultivars segregate as to resistance, thus pointing to a possibly different mode of inheritance of nematode resistance in resistant peach as compared with almond. |
