ESTIMATES OF HETEROSIS FOR SEED YIELD, COMPONENTS OF SEED AND OIL IN LINSEED (LINUM USITATISSIMUM L.)

Published on

A diallel analysis involving 10 parents and their 45 Fts for seed yield and 8 other attributes
determining quality of seed and oil under four different environments was made to have
information on the extent of heterosis and relative magnitude of general and specific
combining ability effects. The extent of heterosis over better parent indicated that seed
yield was most heterotic character followed by stearic acid, oleic acid, linoleic acid and
protein content. Most heterotic and the best specific cross, SPS 23-10 x LC 185for seed yield
and oleic acid and Sweta X LCK 152 for lower value of linolenic acid and oleic acid was
identified as potential combinations showing considerable scope for exploitation of
heterosis inlinseed. Itwas concluded thatselection ofcross combinationbased on heterotic
response would be more realistic than that on sca effects.
