Which type of crop is most suitable for bulk population breeding?

• Bulk population breeding is a method where a large number of individuals from a cross are grown together without individual selection until later generations. This method is most suitable for small grains for several reasons:
● High seed number: Small grains like wheat, barley, and rice produce many seeds per plant, allowing for a large population size essential for bulk breeding.
● Natural selection: Bulk breeding relies heavily on natural selection to eliminate undesirable genotypes. Small grains grown in competition naturally favor individuals with traits like faster growth and disease resistance, which are advantageous in bulk populations.
● Simple harvesting and handling: Harvesting and managing large quantities of seed is easier with small grains due to their smaller size and simpler processing compared to some other crops.
● Predominant quantitative traits: Many important traits in small grains, like yield and disease resistance, are quantitative, meaning they are influenced by multiple genes and environmental factors. Bulk breeding is effective for selecting for these traits due to its reliance on natural selection.
