Abstract:
A field experiment was conducted at ICAR-Central Potato Research Institute RS, Gwalior, Madhya Pradesh during 2018-19 and 2019-20 to evaluate advanced potato hybrids and varieties for growth yield and biochemical parameters for commercial cultivation for the North Central region of India. A total of 14 potato cultivars in which 6 hybrids and 8 varieties were evaluated. The experiment was planned in three replications in randomized block design. Variation in growth parameters viz, seed weight, Plant height (cm), compound leaves and stems/plant and vigor were recorded in two year among hybrids and varieties tested under study. Hybrid MP/10-172 recorded higher non processing grade (<45 mm) tuber yield (t/ha) at 75 DAP and at senescence and hybrid MP/8-1900 for 90 DAP over all others hybrids/varieties. For processing chip grade (45-75 mm tuber) Kufri Lauvkar for 75 DAP, Tauras for 90 days, and MP/10-172 at senescence recorded significantly mean higher yield. Processing chip grade (>75 mm) significantly mean higher yield was recorded at 75 DAP and senescence in hybrid MP/6-39 whereas for 90 DAP high yield was in K. Frysona and hybrid MP/6-39. Significantly mean higher total tuber yield (t/ha) was recorded in MP/6-39 in all three days of potato harvesting 75, 90 and at senescence with Kufri Chipsona 4 at 75 DAP under varied climatic situations. Dry matter content was in acceptable limit in all cultivar except MP/4-816, K. Lauvkar, K. Surya, K. Jyoti and K. Chipsona-4 at 75 DAP and only in MP/4-816 at 90 DAP. Reducing sugar content was low in K. Chipsona-1 and K. Chipsona-4 sequentially at 75 DAP and 90 DAP. Low phenol content recorded in MP/10-172 in both harvesting days. K. Chipsona-1 at 75 DAP and Atlantic at 90 DAP contains mean lowest free amino acid content. These processing hybrids/ varieties can be made suitable to meet the need of the potato industry by harvesting manipulations and will sustain farmer’s income in the changing climate scenario under North-Central India and hybrid MP/6-39 found to be most suitable under the present study.
