Abstract

A line x tester (6 x 3) analysis, involving morphologically diverse females of triticale, was carried out. JNIT-78 was found to be best general combiner for days to maturity, number of grains per ear and grain weight per ear where as JNIT-73 was best for car length and number of spikelets per car. The other best general combiners were JNK6T-233 for peduncle length, 1000- grain weight; and UPT-78269 for plant height and number of ears per plant. F1 crosses showed significant specific combining ability effects for few characters viz., days to maturity (UPT-78269 x JNK6T-229), peduncle length (JNK6T-233 x JNK6T-229), and 1,000-grain weight (JNK6T-233 X JNIT-67). These crosses represent ed the combination of average x poor and best x poor general combiners.
