Genetic analysis for beta glucan, grain protein and other important traits in oats (Avena sativa L.)

Published on

The parents and 45 F1 crosses (excluding reciprocals) in
oats (Avena sativa L.) were analyzed genetically to generate
information on combining ability, nature and magnitude of
gene effects for beta-glucan, grain protein and
physiological traits.The estimates of additive variance were
higher in magnitude than their corresponding dominance
genetic variance indicating the role of additive gene action
for grain protein content and beta-glucan and for
physiological traits like chlorophyll content, leaf area index
and grain yield per plant that showed non additive gene
action. Four parents SKO-207, SKO-208, SKO-209 and SKO-
212 were found to be good combiners for all traits studied.
Twelve cross combinations viz., SKO-204 X SKO-207, SKO-
204 X SKO-208 ,SKO-205 X SKO-208, SKO-205 X SKO-212,
SABZAR X SKO-208, SKO-207 X SKO-208, SKO-207 X SKO-
209, SKO-208 X SKO-209, SKO-208 X SKO-212, SKO-209 X
SKO-212, SKO-211 X SKO-212 and SKO-211 X SKO-213
exhibited desirable positive SCA effect for physiological
traits, grain quality and yield.
