Abstract
Abstract The determination of ploidy level/chromosome numbers in different germplasms is important for better management of genetic diversity and is required before starting concerted breeding programs. The number of chromosomes sets in a cell is one of the defining characters of a species or cultivar. In the present study chromosome counting of Musa spp. were carried out by traditional method and revealed that Elachi trait had 11-12 chromosomes per cell, whereas, in the Poovan, 13-14 chromosomes per cell were seen and in Nendran, about 10-11 chromosomes per cell were counted.
Highlights
Banana (Musa sp.) belongs to the family Musaceae and is among the tallest monocotyledons
The essential part of this experiment i.e., roots were collected from the Musa spp. by removing underground roots
The collected root tips were directly subjected to treated with 0.03% 8-hydroxyquinoline for about 4-9 hours and the roots are transferred to the maceration fixation solution/ storing solution for minimum 12 hours before the slide preparation of the collected materials
Summary
Banana (Musa sp.) belongs to the family Musaceae and is among the tallest monocotyledons. It is one of the earliest crops cultivated by man and still remains as the major staple fruit crop for millions of people in the tropical world. It constitutes an important component of the diet of rural and working-class people, as the fourth important global commodity in terms of the gross value of produce after rice, wheat and maize/milk products [1] and an important source of high calorific energy [Rich source of energy It is the source of digestible carbohydrates and provides essential vitamins B, C and several minerals such as potassium, calcium, and magnesium and has several medicinal properties. Banana is well adopted in India in the region’s varying from humid tropical and semi-arid subtropics, and from the sea level to an elevation of 2,000 meters above mean sea level [2]
