Meiotic changes in Vicia faba L. subsequent to treatments of hydrazine hydrate and maleic hydrazide
Journal Title: Journal of BioScience and Biotechnology - Year 2013, Vol 2, Issue 1
Abstract
Assessing the impact of mutagens for creating variations in crops like faba bean (Vicia faba L.) is an important criterion in the contemporary world where food insecurity and malnutrition is alarming at the doors of various nations. Impact of two chemical mutagens viz. hydrazine hydrate (HZ) and maleic hydrazide (MH) on the two varieties (NDF-1 and HB-405) of Vicia faba were analysed in terms of meiotic behavior and pollen sterility. Since there are not enough data about the effect of these mutagens on the chromosomal behaviors of Vicia faba, this study presents the role of hydrazine hydrate and maleic hydrazide as well as various types of chromosomal aberrations in crop improvement. The lower concentration of mutagens showed less pollen sterility compared to the higher concentrations. Manipulation of plant structural component to induce desirable alternations provides valuable material for the breeders and could be used favorably for increasing mutation rate and obtaining a desirable spectrum of mutation in faba beans based on preliminary studies of cell division.
