Biometrical Journal, 34 (2), pp. 173-177.https://hdl.handle.net/20.500.11766/12894Mutation breeders often estimate an irradiation dose which causes a specified reduction in growth of a biological material. In this paper, we estimate the growth reduction dose (GRD) and its confidence interval, when the dose‐response relationship is of a general polynomial form. We make a realistic assumption that the response at the control dose is a random variable. We compare the estimates, standard error and confidence intervals of GRD with those obtained under a situation where response at control dose is a known constant. We illustrate the procedure with data on the effect of gamma irradiation and Ethylmethane sulphate on shoot lengths of chickpea genotypes.quantitative responsepolynomial regressioninverse estimationgrowth reduction doseJournal ArticleTimeless limited access
