Abstract:
Inheritance of resistance to zucchini yellow mosaic virus (ZYMV) in the interspecific cross Cucurbita maxima × C. ecuadorensis was studied in generations P1, P2, F1, F2, BCP1 and BCP2. The continuous variation presented in these generations implies a quantitative inheritance. The resistance in C. ecuadorensis was partially dominant over that of sensitivity in C. maxima. Several genes with major effects along with genes with minor effects seem to control ZYMV resistance. Both the dominant and the additive contribution to resistance were found to be significant; their interaction was also significant. However, the major contribution was due to the additive rather than the dominance effects. The narrow sense heritability is 0.91. Virus titer as measured by enzyme linked immunosorbent assay (ELISA) was positively correlated (r=0.76) with the intensity of visual symptoms. The efficiency of ELISA as a tool to the breeders, and the use of C. ecuadorensis as a source of resistance to ZYMV are discussed. © 1989 Kluwer Academic Publishers.
