Gene effects for begomoviruses resistance and plant architecture attributes in pumpkin (Cucurbita moschata Duchesne)

Knowledge of gene actions governing begomovirus resistance and plant architectural traits is a prerequisite for successful hybrid breeding programme. Therefore, the associated with these were studied in two intervarietal crosses Cucurbita moschata (C1: Punjab Nawab × MVSR-6711 C2: Nawab P-135). We used generation mean analysis six generations this purpose. Significant differences between means observed all both crosses. The parental lines differed significantly most traits. nature magnitude effects seventeen varied by trait cross. A simple additive dominance model was adequate internode number, leaf length width, petiole length, fruit weight cavity diameter C1 number fruits/plant C2. non-allelic interaction found to be significant majority including per cent disease index squash curl China virus, tomato New Delhi virus their mixed infections, which indicated, that recurrent selection biparental progeny might be useful accumulation genes effects.
