Abstract
To determine the association among yield related traits on grain yield of mutant wheat, an experiment was conducted at the Agricultural Research Farm of R. B. S. College, Bichpuri, Agra (Uttar Pradesh). The application of physical mutagens such as X-rays, gamma rays, and neutrons, as well as chemical mutagens, for inducing variation is well set up. Induced mutations have been applied to the Joint offer of FAO/IAEA Division of Nuclear Methods in Agriculture, more than 1800 cultivars acquired either as direct mutants or derived from their crosses have been released globally in 50 countries. The correlation of twelve characters in wheat induced mutants was investigated. The number of spikelets per spike and spike length both had a significant and positive correlation with yield per plant. Selection for traits that are positively correlated with yield per plant could lead to increased yield. This suggests that selecting for these traits may be more effective in maximising grain yield.
