Selected bulk or modified pedigree/bulk methods are widely used for wheat improvement. Are there other selection schemes that are proven superior to these methods for drought/heat stress tolerance?
you could screen these genotypes for heat or drought tolerance for post-anthesis drought tolerance using chemical methods for Blum 1983. You could used KI 0.4% after 14 days from anthesis.
I think you will have chance to screen and get tolerant genotypes
