Abstract
The use of pesticides for plant protection of high yielding varieties has enormously increased during the recent years as one of the most economical plant protection tools at hand. Such use of these chemical substances has resulted in undesirable side effects such as residual toxicity of the consumed products and sensitivity of certain varieties to these chemicals. The susceptibility of some barley varieties even to low doses of DDT is one of such examples (Hays, 1959). Some of the pesticides have adverse effect on other crop plants in mixed cropping pattern and even on parasites and predators favourable to man (CIMMYT Report, 1967-68). Some of the new hybrids of sorghum and a majority of strains so far cultivated in India are highly susceptible to stem borer and shootfly, if initial plant protection measures are not taken. Therefore, the best approach to avoid insecticidal hazards and reduce losses due to insects is breeding of resistant varieties. A genetic analysis of resistance to stem borer in sorghum is presented in this paper.
