TAILIEUCHUNG - Variation induced in C2 generation of African marigold using colchicine treatment

Variation induced in C2 generation of African marigold using colchicine treatment was conducted in non-replicated trial with six treatments. The seeds of diploid white marigold were treated with , , , , and % colchicine at room temperature for 12 hrs. and the seeds collected from individual plants of C1 generation were used for the experiment to raise C2 generation and germinated in protray. Thirty days old seedlings were transplanted in the field with spacing of 45 × 30 cm in ridges and furrow. Observations on seventeen different types of variants viz. tall, dwarf, broad leaf, narrow leaf, twin flower, orange flower, yellow flower, light yellow flower, multi-layer spreaded flower, single layer spreaded flower, bilayer spreaded flower, button shape flower, flower without central disc, small flower, large flower, plant with single stem and profuse branches were identified and isolated. Variation frequency, treatment efficiency and treatment effectiveness did not follow any specific trend in relation to dose of colchicine. Significant variation among the treatments for all the variants was recorded in C2 generation of African marigold and hence, offers scope for identifying variants. | Variation induced in C2 generation of African marigold using colchicine treatment
