Stylosanthes, variability, heritability, yield

The investigation variability of yield and yield contributing characters in Stylosanthes species was undertaken to study the magnitude of genetic variability of various components towards green forage yield. The ten observations were recorded on green forage yield and yield contributing characters viz., plant height (cm), plant spread (cm), number of primary branches per plant, leaf length (cm), leaf breadth (cm), length of leaf sheath (cm), leaf to stem ratio, green forage yield/plant (g), dry matter yield/plant (g), and crude protein yield/plant (g). The analysis of variance showed existence of considerable variability for all twelve characters. A wide range of variability was observed for almost all the characters studied. The genotypes RS-20-2, RS-20- 11, RS-20-19, RS-20-20, RS-20-21, RS-20-22, RS-20-24, RS-20-25, RS-20-26, RS-20-27, RS-20-29 and RS-20-33 recorded higher green forage yield/plant, dry matter yield/plant and simultaneously other characters. Phenotypic coefficient of variation estimates was slightly higher than genotypic coefficient of variation. High genotypic and phenotypic coefficient of variation was observed for leaf to stem ratio followed by crude protein yield/plant, dry matter yield/plant, crude protein content and green fodder yield/plant indicating ample variability for these characters. All the characters except length of leaf sheath and number of primary branches per plant under study showed high estimates of broad sense heritability. High heritability estimates accompanied with high genetic advance was observed for the characters viz., leaf to stem ratio, crude protein yield/plant, crude protein content and dry matter yield/plant indicating inheritance of these characters due to additive gene action and direct selection of such traits necessary for crop improvement.
