1.	Availability of a limited number of disease resistance genes constrains conventional breeding practices.(a) True(b) FalseThe question was asked by my college director while I was bunking the class.Question is taken from Plant Breeding for Disease Resistance topic in chapter Strategies for Enhancement in Food Production of Biology – Class 12
Answer» Correct answer is (a) True The explanation: Conventional breeding is OFTEN constrained by the availability of a limited number of disease resistance genes that are present and identified in various crop varieties or wild relatives. INDUCING mutations in plants through DIVERSE means and then screening the plant MATERIALS for resistance SOMETIMES leads to desirable genes being identified.
