Effect of dwarfing genes on grain yield in tall X dwarf crosses of wheat (Triticum aestivum)



Effect of dwarfing genes on grain yield in tall X dwarf crosses of wheat (Triticum aestivum)



Cereal Research Communications 16(3-4): 273-275



Indian tall varieties NP846, NP876 and K68 and hybrid 65 were crossed with dwarf varieties Tordo S, Norin, Olson Dwarf, D6899 and S948AL. Plant height and grain yield per plant were measured in the parents and the F1 and F2. The dwarf parents gave a better yield than the tall parents. F1 crosses involving D6899 gave the highest grain yield. Mid-parental heteroris was high for all the F1 crosses except those invloving Olson Dwarf and Tordo S.
