Performance of aromatic rice strains for growth and yield potentials

Abstract

The experiment was conducted at Rice research Institute, Dorki, Larkana, Pakistan to evaluate the growth and yield performance of various aromatic strains. The various varieties and crosses were Lateefy, Jajai-77, D. BasmatixLateefy, IR-8xJajai-77 and Bas.-370xJajai-77. It was observed that aromatic varieties and their crosses initiated flowering between 73 and 105 days. Among the tested strains, Lateefy, Bas.-370xJajai and IR-8xJajai-77 recorded minimum (73-77) days to flowering, followed by D. BasmatixLateefy which took 80 days to flowering. The aromatic rice variety Jajai-77 recorded prolonged (105) flowering days. Maturity days and plant height of the strains also followed the similar pattern, where Jajai-77 showed prolonged maturity days and attained taller plants and recognized as taller or semi dwarf as compared to other rest of varieties and crosses. The grain yields of Lateefy followed by IR-8xJajai-77 and D. BasmatixLateefy were significantly higher than rest of cultivars and crosses. It was concluded that Lateefy aromatic rice had better adoptability in the region by producing satisfactory grain yield. © 2006 Asian Network for Scientific Information.
