Abstract

Sorghum (Sorghum bicolor (L.) Moench) is a cereal plant that has the potential to be cultivated and developed as a source of carbohydrates. The research objective was to identify the morphology and varieties of sorghum plants from several potential areas of West Sumatra, such as Limapuluh Kota Regency, Payakumbuh City, and Sijunjung Regency be used as a source of germplasm. The research was carried out in Limapuluh Kota District, Payakumbuh City, and Sijunjung Regency for six months starting from June-November 2020. The research was carried out with stages beginning with a survey of the location of sorghum planting, identification of plant morphological characteristics, identification of varieties/cultivars/lines, and collection of germplasm sources. Observations were made on the morphological characteristics of plants in the vegetative and generative phases based on the sorghum plant description book. The results showed differences between morphological features in the field and existing descriptions in terms of plant properties, plant height, leaf color, leaf bone, panicle density, panicle shape, panicle length starting from the neck of the panicle, shape, and color of the neck of the panicle.
