C. 3, 1 and 2
D. 1, 3 and 2
Answer: Option B
Solution (By Examveda Team)
The correct sequence of these genotypes in terms of their importance to farmers are:First of all, is Landraces, then Variety under cultivation, and lastly breeding lines.
The term “landrace” has generally been defined as a cultivated, genetically heterogeneous variety that has evolved in a certain ecogeographical area and is therefore adapted to the edaphic and climatic conditions and to its traditional management and uses.
In agriculture, a variety corresponds to a population of plants of a given species that have been selected and cultivated.
Breeding lines are a group of identical pure-breeding diploid or polyploid organisms, distinguished from other individuals of the same species by some unique phenotype and genotype.
