The relationship of different seed coat color and seed yield component of Sorghum sudanense cv. Qita

In order to explore the influence of different seed coat color (black, red and yellow)on seed yield, the period of procreation, seed morphology and seed yield structure of Sudan grass (Sorghum sudanense cv. Qitai) were analyzed in the study. The results of this study showed that the weight of one thousand seeds with black, red and yellow theca were 14.66, 13.36 and 12.77 g (blackredyellow); the seed numbers of single tassel seed with black, yellow and red theca were 1 319, 1 217 and 908 pills (blackyellowred); the single tassel seed yield with black, yellow and red theca was 18.59,16.29 and 14.65 g (blackyellowred); and the total yield of seeds with black, red and yellow were 3 593.52, 2 654.89 and 2 649.60 kg/ha (blackredyellow),respectively.
