Study of Genetic Variation in Yield Components of Wheat Cultivar Bukhtwar-92 as Induced by Gamma Radiation

Abstract

An experiment was conducted to study the induced variation in yield components of wheat cultivar Bakhtawar–92 by gamma radiation during the Rabi season 1997 – 98. Seeds were exposed to 5, 10, 15, 20 and 25 Krad doses of gamma radiation along with an untreated check. The analysis of the data revealed significant differences among the treatments. The most beneficial dose was 20 Krad. The impact of this dose was promising in germination % (96.47), plant height (82.78), number of grains per plant (59.80), and grain yield (3926), while the other doses such as 5, 10, 15 and 25 showed minor fluctuations in their effects.
