INTERRELATIONSHIPS BETWEEN SOME CHARACTERS IN HIRSUTUM COTTON

Published on

WHILE it is essential that a basic yield level has to be maintained, any breeding
project has to take into consideration the improvement in quality also, especially
in a crop like cotton where fibre-quality is the primary component of price-index.
For a simultaneous selection of both these factors influencing monetary returns,
a knowledge of the interrelationships between the components of quality and
those of yield is a pre-requisite. Interrelationships of this nature have been
reported by Patel (1922), Killough and Hofner (1927), Kearney (1928),
Dunlavy (1933), Brown (1935), Sikka and Afzal (1947), Rana (1952), Limaye
(1957) and Venkataraman and Santhanam (1965). However, the degree of
association between these characters, might vary with the environment or with
the material or both. This is supported by the variable results reported on the
correlations between characters in cotton by various investigators. The availability of an elite segregating population of unknown but diverse origin which
formed the basis of some new strains in the Botany Division of the Indian Agricultural Research Institute, has permitted, an examination of the association
between components of quality and those of yield. The results of this study
are presented in this paper.
