Variation in Relation between Yield and Yield Attributes in 'Thompson Seedless' Grape and its Clones

To study variation in the relationship between yield and yield attributes in 'Thompson seedless', 'Tas-A-Ganesh' and '2A clone' vines grafted onto Dogridge rootstock and trained on the extended Y training system, data collected from 120 vines in each variety were subjec...
