Trait based selection of superior Kodo millet (Paspalum scrobiculatum L.) genotypes

Abstract

One hundred and eighty eight germ plasm accessions of Kodo millet (Paspalum scrobiculatum L.) were evaluated in a field study to assess genetic variability, heritability and genetic advance for eight yield component traits. The ANOVA revealed that there were significant differences among the accessions for all the traits studied. High genotypic variance, phenotypic variance, GCV and PCV were observed for dry fodder yield, plant height and grain yield per plant. Broad sense heritability ranged from 97.18 percent for dry fodder yield to 56.63 percent for number of tillers. The highest genetic advance as percentage of mean was recorded by dry fodder yield followed by grain yield per plant and plant height. High heritability coupled with high genetic advance observed in the present study for grain and dry fodder yield per plant indicates that these traits are under the influence of additive gene action. These traits can be considered as favourable attributes for crop improvement through selection.
