GENETIC ANALYSIS OF CERTAIN FIBRE CHARACTERS IN GOSSYPIUM HIRSUTUM L.

Published on

An investigation was undertaken to assess the gene action underlying the inheritance of
fibre traits, viz., 2.5% span length, fibre uniformity, fineness and maturity coefficient, and
to suggest breeding methodologies for improvement of these characters. Mean data of six
generations of five crosses were partitioned into their components. In general, all the traits
were governed by additive, dominance, and digenic nonallelic interaction effects.
However, nonadditive gene action predominated the additive gene action. Hence, one or
two cycles of recurrent selection techniques followed by pedigree method of handling the
segregates could be successfully adopted for improvement of the traits studied.
