Study of the Cytogenetical Effects on Meiotic Chromosomal Abnormalities Induced by Mutagens in
Journal Title: SSR Institute of International Journal of Life Sciences (SSR-IIJLS) - Year 2018, Vol 4, Issue 2
Abstract
An attempt was made to study the Cytogenetical effects of gamma rays and ethyl methane sulphonate on meiotic chromosomal abnormalities in two cultivars viz., PKV-1 and JS-335. The most frequently observed aberrations in meiosis were univalents, trivalent, multivalents chromosomal fragments, desynapsis of chromosome, laggards, and clumping of chromosomes etc. The physical mutagens were more effective than chemical mutagens. The effect of gamma-rays and ethyl methane sulphonate shows chlorophyll mutations such as Chlorina, Xantha, Albina, and Alboviridis in an M2 generation in both the cultivars. Cultivar JS-335 shows more pronounced effect than cultivar PKV-1. Gamma-rays recorded maximum macro mutations as compared to chemical mutagens (EMS). The frequency and spectrum of morphological mutation indicated that variety JS-335 was more sensitive than PKV-1. Different response of the two varieties to various mutagens was noticed.
