C. moschata and C. maxima × C. moschata rootstocks and within the interspecific hybrid rootstocks tested in this study also indicate the feasibility of improving squash rootstocks through selection and breeding to optimize the performance of

F 1 hybrids as rootstocks bypassed the variation and additional selection required of the F 2 generation. Therefore, nurseries have orchards, primarily of J. hindsii with a few J. regia interplanted or grafted onto the black walnuts. The black

Root-knot nematodes are damaging pests of fruit tree crops and numerous other perennial or annual plants. Several rootstock breeding programs using interspecific hybridization have introduced useful traits for size control, adaptation to the new
