Effect of physical mutagen on growth and quality characters of tuberose (Polianthes tuberosa L.)

Author(s): Abhangrao AK, Dr. SS Yadlod and Gourav Ghormad
Abstract: An investigation was carried out at the Department of Horticulture college of Agriculture Parbhani during 2016-2018 on the studies on mutation breeding in tuberose (polyanthus tuberosa L.) was studied and isolation of promising mutants were done. The experimental material Phule Rajani of tuberose variety treated with five doses 0.5Kr,1Kr,1.5Kr, 2.0Kr,2.5Kr along with untreated sample (control).in generation VM1. Results indicated that the mutagenic treatment at lower doses had significant stimul ative effect on some parameters that is, sprouting percentage,, Leaf length, Chlorophyll content, rachis length, spike length, number of opened florets whereas most of parameters had showed decreased at desired level content. that is number of days for bulb sprouting, survival percentage, plant height, Leaf area, stem diameter, number of unopened florets, weight of flower. Higher doses of all mutagen were detrimental for growth parameters. and lower doses of mutagen were beneficial for quality parameters seven mutants obtained in VM1 generation. In VM1 generation Early mutant, Tall mutant, Flower bud colour mutant, Big flower mutant, Number of petal increased mutant, Number of spikes increased mutant. green tinge on flowers tip.
