With reference to dwarfing genes Rht14 and Rht18, consider following statements

They are dwarfing genes of Wheat that are associated with better seedling vigour and longer coleoptiles (sheath protecting the young shoot tip).

Explanation:

Recently, the researchers at the Pune based Agharkar Research Institute (ARI) have mapped two alternative dwarfing genes Rht14 and Rht18 in wheat. Rht14 and Rht18 genes are associated with better seedling vigour and longer coleoptiles (sheath protecting the young shoot tip). The researchers have mapped the dwarfing genes on chromosome 6A in durum wheat and DNA-based markers were developed for a better selection of these genes in wheat breeding lines. Hence both statements are correct.
