Question

Which among the following is incorrect related to producing a new variety through plant breeding?

• A. Pure lines with desirable characters are usually selected as parents
• B. Usually only one in few hundred to a thousand crosses shows the desirable combination
• C. The progeny obtained through hybridisation can be superior to both the parents
• D. The hybrids produced are self-pollinated for several generations till they reach heterozygous state

Answer 1

The correct option is D The hybrids produced are self-pollinated for several generations till they reach heterozygous state

The superior progeny with desirable characters are selected and self-pollinated for several generations till they reach a state of uniformity i.e. homozygosity, so that the characters will not segregate in the progeny.
