Abstract:
The field experiment was conducted at Research-cum-Instructional Farm of Potato & Temperate Fruit’ Research Station Mainpat, (Surguja) Chhattisgarh during the Rabi season in 2020-21. The experiment was laid out in a Randomized Block Designs (RBD) with 3 replications and 9 treatments. The treatment consists of Eight TPS crosses genotypes and one tuber potato genotype Kufri Pukhraj. The result revealed that the TPS crosses genotype PS 8/97-1 x D-150 (F₁C₁) (T₈) significantly superior performance observed as compare to other tested TPS crosses genotypes and tuber potato genotype with represent to growth attributes, yield attributing characters and economics viz., plant emergence (94.87%), Plant height (78.69 cm), number of shoots plant^-1 (8.27), number of compound leaves plant^-1 (64.42), number of tuber plant^-1 (13.87), fresh weight of tuber plant^-1 (427.08 g), tuberization efficiency (2.25), tuber yield (24.08 t ha^-1), gross returns (₹ 433356 ha^-1), net returns (₹ 340967 ha^-1), B:C ratio (3.69), economic efficiency (₹ 3247.30 ha^-1 day^-1) and production efficiency (229.29 Kg ha^-1 day^-1). The TPS crosses genotype PS 8/97-1 x D-150 (T₈) and TPS crosses genotype PT/14-01 x D-150 x D-150 (T₇) both are similar to each other but TPS crosses genotype PS 8/97-1 x D-150 (T₈) was most suitable for the northern hill zone of Chhattisgarh.
