These monogenic lines were fixed with the resis- tance genes and showed clear reactions to blast isolates from the Philippines, however, they also had diverse agro- nomic traits among them. As a result of an evaluation of culm length, panicle length, days to heading, 100-grain weight, panicle number, spikelet fertility, leaf length, and leaf width over 4 cropping seasons, significant differencesbetween the monogenic lines and the recurrent parent, LTH were observed (data not presented).
