COMPONENTS OF GENETIC VARIATION AND RESPONSE OF SELECTION IN PEARL MILLET (PENNISETUM TYPHOIDES)

Published on

An investigation was conducted in pearl millet composite JOB GT-1 to estimate the
components of genetic variance and heritability for yield and related characters using
NCO-I. The dominance variation (O'~) was very high for number of ears/plot and ear
weight/plot, while the same estimate attained a negative value for plant height and ear
length, indicating the preponderance of additive gene action in their inheritance. The
heritability in narrow sense was high for ear length. Among the various methods of
selection for which theoretical responses were calculated, mass selection appeared suitable
for all characters.
