GENETIC VARIABILITY AND CHARACTER ASSOCIATION IN BROOMGRASS (THYSANOLAENA MAXIMA ROXB.)

Published on

The nature and magnitude of genetic variability and their inter-relationship was studied
for production of flowering shoots and its six component traits in seven morphotypes of
broomgrass (Thysanolaena maxima Roxb.). Ambadola Local and Kainpur Local performed
significantly better than others. High estimates of genotypic coefficients of variation,
heritability and genetic advance were observed for production of flowering shoots, plant
height and number of raches, indicating their reliability for effecting selections. Number
of flowering shoots had high significant positive association with plant height, tillers per
plant, raches per plant and panicle length both at genotypic and phenotypic levels. Hence,
the studies revealed the importance of plant height, and number of raches as selection
criteria for improvement of production of flowering shoots in broomgrass.
