Question

Which of the following is a correct match between crop, variety and resistance to diseases?
A. Crop- Wheat, Variety- Himgiri, Resistance to disease- White rust
B. Crop- Brassica, Variety- Pusa Sadabahar , Resistance to disease- Black rot
C. Crop- Cowpea , Variety- Pusa Komal, Resistance to disease-Bacterial blight
D. Crop- Chilli, Variety- Pusa swarnim, Resistance to disease- Chilli mosaic virus

Answer 1

Hint:- The crops now produced are genetically modified and are grown in such a way that they have developed resistance to some of the diseases. The genetically engineered crop is used to increase the crop yield of the plant and it increases the resistance of the plant to the disease.

Complete Answer:-Pusa Komal is a disease-resistant variety of cowpea. These plant varieties are developed by the process of hybridization. They are resistant to bacterial blight which is an early seasonal disease of the plant. Pusa swarnim is a variety of the plant brassica. It is developed to have resistance from white rust. Albugo candida causes white rust disease in the plant. This disease leads to chlorosis on the leaf surfaces, swelling of the roots, and have white outgrowths on the stems. This disease can also cause deformity of the flowers.
Pusa sadabahar is a resistant variety of chili. It is resistant to Chili mosaic virus. It produces chili for three continuous years. It is also resistant to tobacco mosaic virus and leaf curl disease. This disease leads to leaf rolling, bushy growth of the plant, and necrosis. Himgiri is a variety of wheat plants. It is resistant to bacterial blight of leaf and stripe rust. It is a hybridized variety of wheat. It is also resistant to diseases of yellow rust and hill bunt.

So, the answer is Option C - Crop- Cowpea, Variety- Pusa Komal, Resistance to disease-Bacterial blight.


Note:- The hybridized variety of plants is known to be disease resistant. It is also used to increase the yield of the plant variety. The new plant varieties have better quality than the original plants. The plant variety which is produced by genetic modification is known as genetically modified crops.
