After treatment of two varieties of Brassica campestris L. (2n=20), T10 and T151 with radioactive chemicals P32 and S35, having different concentrations, aberrant cells, for studying the effects were scored in meiosis.
According to the nature of abnormalities in metaphase and early anaphase cytological effects and origin of different abnormal configurations were explained.
Significance of probability of nature of abnormalities was estimated by X2 test and estimate of aberration rates were based on p=n-n/N and S.E.=√p(1-p/n) was also considered as proportion abnormalities to the total confidence limits. Sampling error was also calculated per treatment in percent to record optimum sample size for analysis.
Linearship between treatments and cytological aberrations was shown.
