Question

In plant breeding programme, haploid plants are important because:

• A. They are disease resistant
• B. They are more vigorous
• C. They require less nutrients
• D. They are used to obtain homozygous line

Answer 1

The correct option is D They are used to obtain homozygous line

Haploids are used in plant breeding, especially for the production of homozygous plants. In crop impovement programme, haploids are important because they form perfect homozygous lines. Homozygous are the pure line resulting from successive self pollination. Considerable homozygosity can be easily obtained from haploid plants.
