Title : Advanced Varietal Trial

Author : R.Narasimhan,R .S.Sachan,G.S.C.Rao, A.T. Yaragattikar and R.G.Menon

Year : 1979

A trial was laid out in a view to select most promising varieties specifically suited for June planting and summer harvesting. For this six promising genotypes of the region i.e. Co 6415, Co 419, Co 997, Co 7704, Co 62175 and Co 740 were planted on 4th July 1979 in latin square design with six replications. Data on yield and quality parameters were taken at monthly intervals from April to July which is appended in Table 4. It was found that the early maturity cane Co 6415, Co 7704, Co 997 appeared to be best suited for Kharif planting. The quality is in the order of Co 7704, Co 6415 and Co 997.
