Abstract

INFLUENCE OF INDUCED MUTAGENESIS ON SOME PRODUCTIVITY PARAMETERS IN GENERATIONS M2 AND M3 IN SUSAN (SESAMUM INDICUM L.)

Increasing mutation in crop plants is an effective approach in improving crops with a narrow genetic base, such as sesame. The basic aim of this study is to determine the effect of induced mutagenesis on some parameters of productivity in the Kadet sample (200 – 500 Gy) in the M2 and M3 generations. In the statistical data processing, it was found that in M2 – all doses (200 – 500 Gy) are considered to be more productive compared to the control, and in M3 – the doses of 300 Gy and 500 Gy recorded higher values compared to the Kadet control. Also, the Kadet sample with a dose of 500 Gy according to the productivity parameter per plant was determined by a strong correlation with the number of capsules per plant and the number of seeds per capsule, and at a dose of 300 Gy these parameters had an average correlation.

Keywords: sesame, control, mutagenesis, productivity, generation.
