Collection and evaluation of Korean red rices Ⅷ. Flowering characteristics

In order to evaluate the Korean red rices as useful germplasm, ten lines of long grain red rices and ten lines of short grain red rices were tested for flowering characters such as rate of opened floret, angle of opened floret, duration of anthesis and stigma exsertion rate. Rate of opened floret of the red rices was higher than that of cultivars Seomjinbyeo and Samgangbyeo. Angle of opened floret and duration of anthesis of the short grain red rices were significantly higher and longer than those of cultivated variety Seomjinbyeo, however those of the long grain red rices were almost same as those of the cultivated variety Samgangbyeo. Stigma exsertion rate of the red rices was mostly higher than those of the cultivars Seomjinbyeo and Samgangbyeo. Thus flowering characters of the red rices appeared to be more effective for outcross than cultivars.
