Abstract

Five out of the ten tetraploid varieties of grapes produced at the Indian Agricultural Research Institute, New Delhi, came to fruiting. All of them matured earlier than their diploids. Detailed investigation in two of the varieties revealed that in the tetraploids, period II of the growth of berries was shortened, rates of period III growth were higher, TSS accumulated earlier and all the seeds were floating seeds (empty). It appeared that the late abortion of seeds resulting in empty seededness and earliness of maturity of bunch were associated with each other.
