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.
