Among the plant characters associated with lodging and
nitrogen responsiveness, height is predominant factor
affecting loging resistance (SCARASCIA-MUGNOZZA 1970) and
characters such as straw architecture exert an influence on
polygenic trait like grain yield (LARIK et al. 1980).
It is therefore necessary to take into consideration all the
related plant attributes in any meaningful genetic
evaluation of wheat mutants. The present investigation was
therefore, initiate to study the effectiveness of different
fertilizer levels in enhancing grain yield in winter
wheats.
Materials and Methods
The material originated from different doses of gamma rays
(25 and 35 kR) of varieties Indus and Nayab of bread wheat
received through the courtesy of Head Plant Genetics
Division, Atomic Energy, Agricultural Research Centre,
Tandojam. Triticum aestivum L., Phenotypically stable
mutants and Pak-70 were evaluated for straw and yield
characteristics under different fertilizer levels of
nitrogen, phosphorous and their combination.
The details of treatments are given as under:
