Alternative crop of jute is? While the cause for the disparate numbers is unknown, it may arise because of an XO sex determination mechanism , where males (2n=17) lack the sex chromosome and therefore have one less chromosome than the female (2n=18). These chromatids are genetically identical Table 1. C. hirtus has a chromosome number 2n=4x=28 (Sinha et al., 2011; Flora of North American Editorial Committee, 2016). A: Chromosomes are the thread like structures which are located in the nucleus. Corchorus is a genus of about 40-100 species Chromosomal Aberrations: These result from chromosomal aberration disturbing the normal number or structure of the chromosomes. Results showed 2n =14 as the diploid number. Examples-Manila hemp, Sisal, New Zealand hemp. The karyotypes of the two cultivated species (C. capsularis … Notify me. Most Corchorus species are diploids with 2n = 14, while wild species like, C. cunninghamii, C. hirtus, C. junodii, and C. siliquosus are similar in chromosome structure and are tetraploids (Belay, 2011). The KCS genes of four cottons were located on the chromosomes of the corresponding cotton species . Wild crop relatives are now playing a significant part in the elucidation and improvement of the genomes of their cultivated counterparts. However, jute chromosomes 5 and 6 shared synteny with a single cocoa chromosome 1.
