Abstract
Bases of shoot apical cuttings of chrysanthemum morifolium cvs. Super Yellow and Maghi were dipped in 0.0, 0.12 and 0.18% of the sodium azide (SA) for 6 and 12h. Cuttings survivability was immensely hampered and reduced once treated with 0.18% for 6h. Almost, all mean of investigated traits did not highly varied between the control and treated plants. Nevertheless, their ranges of plant heights, number of shoots/plant, number of flower head, flower head diameter, flower head fresh and dry. This remarkable disparity of the plant traits were accomplished with high σ2P and σ2G compared with the control plants on both seasons. High heritability combined with high genetic gain as a percent of mean (GA) was observed for number of branches, number of flower heads and flower head dry weight. Hence, these metrical traits require simple selection breeding. However, high H coupled with low GAM was recorded for number of days to bloom and flower head diameter indicating non-additive gene action. Low H and GG was notice for flower head fresh weight. The knowledge on H of traits is helpful in deciding the selection procedure to improve the trait given. Nevertheless, SA that caused diversity on plant growth and flowering traits still warrant further examinations.
