Selection for grain yield per plant under heat stress in bread wheat (Triticum aestivum l.) [electronic resource].

Includes reference.

Divergent phenotypic selection lor grain yield per plam under heat stress in wheat (Triticum aestivum L) was perfomled in five F, populations derived from crosses established between eight local landraces quite variable in heat susceptibility index under the heat stressed condition of a late sowing date, Selection was imposed on 200 F2 spaced plams for each of the five populations where the highest and the lowest five plants in grain yield were selected. Responses in grain yield per plant and the correlated response in a number of agronomic traits were measured in the F3 descending families of the selected F, plants against the F, bulks.
