Abstract
This study was conducted to find out the optimum cultural method for hybrid seed production of Chalok 2. Higher seed yield was obtained when KW3 was used as a seed parent (female). KW7 was shown Higher barren stalk occurrence which caused significant seed yield reduction when it was used as a seed parent (female). The ratio of female (KW3) to male (KW7) rows with 4 to 1 had higher seed yield than that of 2:1 or 3:1. In case of using KW3 toy a seed parent, KW3 was susceptible to stem and ear rotting disease. The 35th day after silking was optimal period to harvest due to higher 100-grain weight, lower rotten grain, and higher germination rate.
