• B. produce grains like spring variety
• C. do not need vernalization
• D. can not produce flowers and mature grains

Answer 1

The correct option is D can not produce flowers and mature grains

Vernalisation refers to the promotion of flowering by a period of low temperature. Some important food plants, wheat, barley, rye have two kinds of varieties: winter and spring varieties.

The ‘spring’ variety are normally planted in the spring and come to flower and produce grain before the end of the growing season.

Winter varieties, however, if planted in spring would normally fail to flower or produce mature grain within a span of a flowering season. Hence, they are planted in autumn. They germinate, and over winter come out as small seedlings, resume growth in the spring, and are harvested usually around mid-summer
