“…But cultivated clones occurring without fertile seeds like "Bhimkol" or "Athiya-kol" in Assam and "Elavazhai" in south India have been proved as distinct commercial varieties in these regions. These two clones cannot be considered as truly wild species due to long time cultivation by the local habitats mainly through suckers and the existence of the species either in wild or feral state is yet to be established (Subbaraya, 2006;Joe et al, 2014).

Musa balbisiana was first described as a species by an Italian botanist Luigi Aloysius Colla in 1820 based on the type collected from Southeast Asia (India Orientali). Later on brief descriptions were provided by Cheesman (1948) and Moore (1957). This species is very much important from the evolutionary viewpoint as it is one of the two parent plants together with M. acuminata Colla for most of the cultivated bananas of present day. Southeast Asia is regarded as centre of origin of M. balbisiana (Hore et al., 1992) and was also reported from Srilanka, India, Thailand, Malaya, Indonesia, Philippines and New Guinea (Cheesman, 1948;Sulistyaningsih et al., 2014). There is very little variation in this species in the interspecific level and no subspecies has been described so far under it (Subbaraya, 2006). However, subsequent workers described five varieties on the basis of intraspecific variations of the species viz., M. balbisiana var. balbisiana Colla, M. balbisiana var. andamanica D.B. Singh et al., M. balbisiana var. brachycarpa (Backer) Hakkinen, M. balbisiana var. liukiuensis (Matsum.) Hakkinen and M. balbisiana var. elavazhai A. Joe et al. In India the species is widely occurring with intraspecific variations in northeastern states, Andaman and Nicober islands and in some parts of south India. Wild or feral forms of M.balbisiana are considered to possess fertile seeds. But cultivated clones occurring without fertile seeds like "Bhimkol" or "Athiya-kol" in Assam and "Elavazhai" in south India have been proved as distinct commercial varieties in these regions. These two clones cannot be considered as truly wild species due to long time cultivation by the local habitats mainly through suckers and the existence of the species either in wild or feral state is yet to be established (Subbaraya, 2006;Joe et al., 2014). However, the present investigators recorded wild populations of M. balbisiana Colla from Dima Hasao district of Assam.During the field work conducted between the years 2012-14 for taxonomic study on the genus Musa L., the authors collected certain specimens of seed propagated plants occurring wild and in semi-domesticated state in Assam which are known as "Sepa-athiya". It differs from M. balbisiana in a number of attributes. The plants are propagated both through seeds and by suckers. Further, unlike the cultivated clones of M. balbisiana, the fruits of the collected plants are not edible because of the presence of numerous compactly arranged seeds with scanty flesh. However, the other parts like pseudostem, leaves and inflorescence are used as that of M. balbisiana. Considering the above differences of the collected specimens with that of M. balbisiana, a new variety viz., Musa balbisiana var. sepa-athiya is proposed and described.Musa balbisiana var. sepa-athiya Borborah, Borthakur & Tanti, var. nov. (Fig. 1). Diagnosis: Musa balbisiana var. sepa-athiya is very much similar to M. balbisiana var. balbisiana but differs in the short peduncle (25-27 cm in M. balbisiana var. sepa-athiya vs. 30-35 cm in...

“…The family comprises about 132 taxa, out of which 34 wild taxa in 2 genera, Ensete and Musa, are mainly distributed in the northeastern states of India, bordering China, Myanmar, followed by the Western Ghats, the Eastern Ghats and the Andaman and Nicobar Islands (1). In Northeast India, out of 29 taxa, 20 are endemic to the region, of which 15 are restricted to the northeastern states of India (2).…”

“…The combinations of these genomes have resulted in various genotypes of cultivated edible banana clones, exhibiting different genomic composition and ploidy levels such as AA, AB, AAA, AAB, ABB, AAAB, AABB, and ABBB [11]. In India, the genus is represented by 37 wild taxa-of which 20 are endemicand is largely distributed in northeastern states and followed by Western Ghats, Eastern Ghats, and Andaman and Nicobar Islands [12,13]. However, the family Musaceae is well known for its vast genetic diversity and thought to have originated from south and Southeast Asia [13,14].…”

The genome size variation is an important attribute in evolutionary and species characterization. Musa L. is regarded as one of the taxonomically complicated genera within the order Zingiberales, with more than 75 species from wild seeded to seedless cultivars that may be diploid, triploid or tetraploid. The knowledge of total nuclear DNA content in terms of genome size and ploidy level in wild species of Musa is absolutely important in evolutionary and genomic studies. Methods: In this paper, chromosome spreading was performed via protoplast isolation and a fast air-dry dropping method and flow cytometry were used with Raphanus sativus L. (Brassicaceae) as a standard for ploidy and genome size estimation. Results: The results showed that genome size (2C) varied amongst Musa species, based on the ratio of G1 peak positions. The lowest genome size (2C) was found in M. balbisiana var. andamanica (1.051 ± 0.060 pg) and the highest genome size (2C) was recorded for Musa ABB.cv. Meitei-hei (1.812 ± 0.108 pg) for the section Eumusa. Among the species belonging to the section Rhodochlamys, M. rosae had the lowest 2C content of 1.194 ± 0.033 pg whereas the highest nuclear DNA content (2C) was observed in M. velutina (1.488 ± 0.203 pg). Cytogenetic analysis revealed that the chromosome number of 14 wild Musa species was 2n = 22, while 1 species—Ensete glaucum—showed a chromosome number of 2n = 18 (diploid), and for 3 species, the chromosome number was 2n = 33 (triploids). An association study based on the Pearson correlation coefficient showed 2C nuclear DNA content was significant and positively correlated with ploidy level (R = 0.9) and chromosome number (R = 0.84). Conclusions: The present study provides reliable information on the genome size and ploidy level of wild Musa species from the Indian region through flow cytometric analysis, which could be further utilized in taxonomic and crop improvement programs. For the first time, the nuclear DNA content of eight wild diploid and three triploid Indian species were estimated and reported. Genome size could be an effective indicator in identification of species and evolutionary studies in Musa with varying ploidy levels and morphological similarities.
