Abstract

A field experiment was conducted in the Horticulture Research Farm, Andro,
Imphal East during 2014 – 2015. The treatments consisted of IGDa-4, IGDa-2, NAUDa-2, Da199, Da-11, Da-25 and local cultivar as check. The physiological parameters at 135 days after
planting viz., leaf area index (2.83), harvest index (76.37%) and crop growth rate (3.10 g day-1
)
were highest in Local cultivar. Da-25 was highest in net assimilation rate (0.007 g-2
day-1
) and
relative growth rate (0.0078 g-1
day-1
). Length of the tuber (27.40 cm), single tuber weight
(1228.77 g and tuber weight per plant (1228.77 g) and tuber yield (15.17 tha-1
) were highest in
Local cultivar, while diameter of the tuber (12.13 cm) and number of tubers per plant (1.67) were
highest in Da-11 and Da-199, respectively. Highest dry matter percentage (34%) and starch
(21.67%) content were in Da-11 and IGDa-2, respectively
