Evaluation of the Three Generation of Seed Potatoes to Assess Effects of Degeneration Caused by PVY and PLRV

The experiment was conducted to detect the effect of PVY and PLRV on growth and yield of four different potato varieties namely Asterix, Cardinal, Diamant and Granula resulting the rate of degeneration of potato varieties at three successive cropping seasons viz. 2010-11, 2011-12 and 2012-13. Three different generations namely 1st, 2nd and 3rd generation were used. Positive significant correlation was found between aphid population and spread of PVY and PLRV. The percent infection of PVY was ranged from 10.8-16.7 %, 19.2- 37.5% and 39.2-61.7% in 1st, 2nd and 3rd generations, respectively depending on the varieties. Whereas, PLRV infection varied from 5.0-10.0%, 27.5-30.8% and 37.5-52.5% in 1st, 2nd and 3rd generations, respectively depending on the varieties. Asterix and Diamant are more tolerant than that of Cardinal and Granule. 1st generation was produced maximum number of tubers per hill, yield per hill and seed yield per plot compared to 2nd and 3rd generations all the four potato varieties. Diamant showed less degeneration effect on number than the other varieties. Asterix and Diamant performed better than that of Cardinal and Granule in all the cases. PVY causes more severe reduction of yield per hill than that of PLRV.
