Evaluation of Selected Varieties of Processing Potato under Chhattisgarh Plains

An experiment was conducted to evaluate the selected varieties of processing potato ( Solanum tuberosum L.) under Chhattisgarh plains. The experiment was laid out in a randomized block design with three replications and nine treatments/genotypes during Rabi 2009-10. The results revealed that the highest per cent emergence was recorded in Kufri Chipsona-1 (93.26%), the maximum number of leaves plant -1 was counted in Kufri Surya (326.30), significantly the maximum number of shoots plant -1 (5.36) and tallest plant (62.66) was found in Kufri Chipsona-1 at 60 DAP, no mark differences was observed among all the treatments as regard number of stolen plant-1 but relatively higher number of stolen plant-1 was noted in Kufri Surya (31.52) at 60 DAP and Kufri Chipsona-1 (33.02) at 75 DAP, tuberization efficiency was found relatively higher in Kufri Chipsona-1 (3.75 g), the highest number of marketable (11.56) and unmarketable (4.11) tubers as well as tuber yield plant- 1 of marketable (440 g) and unmarketable (57.7 g) was counted in Kufri Chipsona-1. The highest total yield (280 q/ha) was recorded in Kufri Chipsona-1.
