Agronomic performance of promising bread wheat mutants under different fertility regimes-III. genetic potential

Evaluation of five promising mutants of wheat (Triticum aestivum L.) WM-89-1, WM-56-1-2, WM-6-17, WM-81-2 and WM-120-3 along with a standard commercial variety Pak-81 as check, was done at NIFA during Rabi, 1984-85 to study their genetic potential and response to different levels of N-P. The N-P combinations used were 0-0, 95-35, 115-45, 135-55, 155-65, 175-75 and 195-85 kg/ha. Mutant lines WM-89-1 and WM-81-2 produced greater number of grain/spike, higher grain weight, higher grain yield and harvest index values than the rest of the mutants and check. The combined application of N and P produced the highest grain yield at the dose rate of 135-55. (author)
