Abstract:

Genetics of fibre elongation in diploid cotton was studied during 2015-16 at University of Agricultural Sciences Dharwad. Segregating population (F2) of the cross between, Fuzzy linted (FL) x Fuzzy-lintless (Fl) of diploid cotton were evaluated to study the genetics of fibre elongation. The segregation was in the ratio 15(linted): 1(lintless) to indicating duplicate dominant gene action and lintless trait is controlled by double recessive genes. Scanning electron microscopy (SEM) at fibre initiation stage i.e., two days post anthesis (2 DPA) to observe the development of fibre initials on epidermal layer of ovules, revealed the presence of fibre cell initials in both FL and Fl line; however the fibre initials in Fuzzy-lintless (Fl) line did not elongate to become lint, unlike FL, where part of initials elongated into lint (fibre) cell.


Keywords: Fiber initiation, Fibre elongation, Fuzzy.
