GENETIC CORRELATION AND PATH COEFFICIENT STUDIES FOR FASCICULATED ROOT YIELD IN SATAVAR (ASPARAGUS RACEMOSUS WILLD.)

摘要

Eight accessions of Asparagus racemosus were evaluated for dry fasciculated root yield per plant and its component characters. The accessions exhibited significant differences for all the traits. Dry fasciculated root yield per plant, plant height, fasciculated roots per plant and root length exhibited very high heritability coupled with relatively high genetic gain. Dry fasciculated root yield per plant showed significant phenotypic and high genotypic correlation with fasciculated roots per plant and fresh fasciculated root yield per plant. Similarly, fresh fasciculated root yield per plant showed positive and high correlation with fasciculated root per plant but negative and significant correlation with fasciculated root length. Fresh fasciculatedroot yield per plant showed maximum direct effect followed by plant height and diameter of fasciculated root canopy.
