Irradiation in Combination with Higher Storage Temperatures Maintains Chip‐Making Quality of Potato

Abstract

Freshly harvested and well-suberized potato (Solanum tuberosum) of varieties Kufri Jyoti, Lady Rosata, Kufri Laukar, and Hermises were processed by radiation at 78/149 Gy (D(min)/D(max)) dose and stored at 12 +/- 2 degrees C for 8 mo from March to October for assessment of chip-making quality. The firmness of the tubers in all the varieties processed remained unchanged during the period of storage. Chips of the desirable quality could be prepared from 7-mo stored Lady Rosata, Hermises, and Kufri Jyoti varieties, whereas, in Kufri Laukar, the quality chips could be prepared with tubers stored not beyond 5 mo. In the present study, varietal differences were found to influence the chip-making quality of irradiated potato. Tubers with high reducing and total sugar (>2%) were found to be unsuitable for chip-making. The quality of chips, however, was not affected much by the change in internal color of the tuber during storage beyond 6 mo. The results suggested the efficacy of gamma irradiation for ensuring availability of the processing quality potato during lean periods from September to October.

Evaluation of Potato Varieties for Their Suitability under Northern Telangana Agro Climatic Conditions

“…KufriJyothi reported least tuber yield per plot (8.832 kg) and tuber yield per hectare (19.627 t/ha). The results are in agreement with other researchers who investigated that tuber yield varies significantly with variety, location and genotypes x environment interaction (Elfinesh, 2008, Gebreselassie et al, 2016, Pandey et al, 2004and Kumar et al, 2007 …”

Evaluation of Potato (Solanumtuberosum L.)Varieties for Yield and Yield Components in Eastern Ethiopia

“…Patel et al, (2008) and Kumar et al, (2007) also reported that maximum yield of small size tubers may be due to higher number of tubers as well as varietal character and adaptability or establishment effect of other growth attributes. Muthurajet al, (2005) reported that, the effect of heredity was significant with regard to tuber grades.…”
