PREDICTION OF HETEROSIS AND COMBINING ABILITY FOR YIELD AND YIELD CHARACTERS AT SEEDLING STAGE IN SWEET PEPPER (CAPSICUM ANNUUM L.)

Published on

An attempt was made to predict heterosis and combining ability for yield and yield
components at seedling stage in crosses between 12 powdery mildew resistant (PMR) lines
and 3 powdery mildew susceptible (PMS) testers of sweet pepper. Heterosis over MP, BP
and the best parent was recorded for seedling height, number of leaves, growth rate, leaf
production per week, and number of basal and secondary roots at transplanting. Results of
line X tester analysis and correlation studies suggest that Fl hybrids with high sca effects
and parents with high gca effects for yield and yield components can be identified at
seedling stage using parameters like height at transplanting and seedling growth rate.
 

Keywords: Combining ability, heterosis, seedling analysis, sweet pepper.
