LINE X TESTER ANALYSIS OF COMBINING ABILITY IN SNAKEGOURD (TRICHOSANTHES ANGUINA L.)

Abstract

Line x tester analysis was conducted in snakegourd to study the combining ability among different lines. The gca effects were significant for yield/plant and fruits/plant for tire lines TA-I02, TA-I00 and TA-89. The accessions TA-82 and TA-77 were good combiners for earliness. The crosses TA-89 x TA41, TA-77 X TA-41, TA-I02 xTA-70 and TA-I02 X TA-99 exhibited high sca effects for yield/plant and fruits/plant. The crosses TA-77xTA-70, TA-87 X TA-41 and TA-89 X TA-41 showed high negative sea effects for days to first fruit picking.
