More than 70% of potato in India is grown in north Indian plains; the largest number of cultivars has been developed for this region.

Introduction

The maturity groups for the hills are early (120-125 days); medium (130-135 days) and late (135-145 days). Each variety varies in its potentials to contribute towards yield basing on the agro ecological conditions.

The cultivars developed for the plains fall in 3 maturity groups i.e. early (70-80 days); medium (90-100 days) and late (100-110 days).

Cultivars have also been developed for north Indian hills and special problem areas viz., Sikkim and North Bengal hills and South Indian hills (Table 5).

Biotic and a biotic resistance varieties In India, the focus has been on developing cultivars resistant to Phytophthora, suitable under short-day conditions

In fact, Indian potato varieties are already popular in many of the countries.

The selections I-822 and I-1085 are grown as the cultivars Krushi and Sita. Furthermore; Indian potato varieties enjoy a high degree of consumer preference. Two Indian varieties, Kufri Chandramukhi and Kufri Lauvkar, are very popular in Afghanistan and can be equally good in other central Asian countries.

Thus, the varietal development programme of India would better suit rather than the long-day variety programmes. The emphasis has also to be on developing heat tolerant and drought resistant cultivars.
