Preference of rugose spiralling whitefly to coconut hybrids with respect to biophysical characters

Among the different coconut hybrids tested CRP-509 proved to be the best hybrid based on various bio-physical parameters such as more height, less number of leaflets per leaf, minimum leaflet length and width. The plant height was significant and negatively correlated with percent RSW infestation, whereas total number of leaflets per leaf, leaflet length and width exhibited significant and positive correlation with percent RSW infestation.
