GENETIC ANALYSIS OF RESISTANCE TO LEAFHOPPER (OROSIUS ALBICINCTUS DIST.) IN SESAME

Published on

Crosses were made in a 9X9 diallel set (excluding reciprocals) involving diverse parents to
study the inheritance of resistance to leaf hopper (Orosi"s albicinct"s Dist.) in sesame.
Combining ability analysis as well as predictability ratio revealed the involvement of both
additive and nonadditive gene effects. The parents B-14 and Hr-l had significantly
negative gca effects, indicating the possibility of using them as donors of leaf hopper
resistance. The crosses B-9 x 5-14 and Anand-14 X Sekhar were good specific cross
combinations which involved at least one high general combiner.
 

Keywords: Sesame, leaf hopper, resistance, combining ability.
