Question

Write any four varieties of Wheat and their characteristics.

Answer 1

Hint: Hybrid varieties are the result of crossing two different breeding lines. They differ from Pureline varieties and open pollinated varieties in that the seed they produce will not be saved and replanted but the parental lines have to be crossed each time to produce new seeds.

Complete answer:
Hybrid seed production requires the enforcement of an efficient cross pollination between wheat inbred lines that overcomes the naturally autogenous pollination mode of wheat. This is practically achieved by planting male sterile maternal parents with good pollen recipient properties in close proximity to paternal plants with good pollen shedding properties. Thus effective male sterility of the maternal plants is a general requirement that can be based on different mechanisms.

Four hybrid Varieties of Wheat are
- Sonalika: High yielding wheat variety with disease resistance introduced in the Green Revolution.
- Kalyan Sona: High yielding wheat variety with disease resistance introduced in Green revolution
- Himgiri : Resistance to leaf and stripe rust and hill blount disease.
- Atlas 66: Biofortified hybrid wheat variety with high protein content

Note: Hybrid plants are usually more vigorous and faster growing than other plants. This can be great for those working in agriculture as they can reap greater crops and make more money. These plant types are also more resistant to many diseases and afflictions, which affect parent plants.
