Gamma ray induced positive alterations in morphogenetic and yield attributing traits of finger millet (Eleusine coracana (L.) Gaertn.) in M2 generation

Induced mutagenesis by gamma rays plays a potent promising technology to be applied for crop improvement through breeding methods, especially in tiny florets possessing self- pollinated plants such as cereals. Finger millet (Eleusine coracana (L.) Gaertn.) which always ensured valuable nutrients, well famine tolerant supply food global population throughout the year. The present study was performed assess spectrum and frequency of macro mutants induced radiations M2 generation finger millet. chlorophyll viz., albina, xantha, chlorina viridis morphological tall, dwarf, bushy, brittle stalk broad leaf were recorded different doses. Among mutagen doses 600 Gy dose maximum increase mean values phenotypic genotypic coefficients variation plant height (cm), number leaves per plant, length tillers panicles panicle length, days 50% flowering, 1000 seeds weight. Except number/plant seed weight, all traits showed high heritability results revealed progressive decrease quantitative with provides an idea about optimum from pool that could employed future programmes.
