Question

Pusa snowball K-1 and pusa A-4 are resistant from
A) white rust and jassids respectively
B) Curl blight black rot and aphids respectively
C) Black rot and shoot borer respectively
D) Leaf curl and fruit borer respectively

Answer 1

Hint: A crop is a product of a plant or plant that can be cultivated for benefit or subsistence and harvested. Crops fall into six groups when used: food crops, feed crops, fibre crops, petroleum crops, ornamental and industrial crops. For human consumption, food crops, such as fruit and vegetables, are cultivated.

Complete Answer:
Pusa Snowball K1: The cross between EC-12013 x EC-12012 and released from IARI, Regional Station, Katrain (Kullu Valley) is a derivative of the Pusa Snowball variety of Cauliflower. It is a late variety that is perfect for the cool season. Curds are very lightweight in colour, medium in size and snow-white.

Pusa A-4: Okra variety A-4 is resistant to the Jassids, Aphids & Shoot and Root Borer tolerant Yellow Vein Mosaic virus. The fruits have a lower volume of mucilage and a longer shelf life. It is ideal for cultivation throughout the year, except during low temperature periods.

Curl blight black rot and aphids are immune to Pusa snowball K-1 and Pusa A-4, respectively.
It has the best snow-white curd consistency among the snowball forms and maintains it even if the harvesting is delayed. In texture, the leaves are puckered, serrated and light green.

Pusa A-4: Okra variety A-4 is resistant to Jassids, Aphids & Shoot and Root Borer Yellow Vein Mosaic virus tolerant. The fruits have a lower volume of mucilage and a longer shelf life. Except during the low temperature season, it is suitable for cropping throughout the year.

The correct Answer is option (B) 'Curl blight black rot and aphids respectively'.

Note: At IARI (Indian Agricultural Research Institute), Regional Station, Katrain (Kullu Valley), Pusa snowball K-1 has been developed and is tolerant of black rot.
