Answer: Option C
Solution:
An inbred is used as a tester in recurrent selection for SCA.Plant lines are considered inbred when the offspring (progeny) from a self-fertilized plant looks identical to the parent, as well as identical to one another.
It was originally proposed by Hull in 1945. It’s a form of recurrent selection that is used to improve the SCA of a population for a character by using a homozygous tester referred to as (RSSCA) recurrent selection for specific combining ability.
