Jowar (Sorghum bicolor L. Moench) is an annual plant belonging to family Gramineae. Sorghum originated in Africa, and is now cultivated widely in tropical and subtropical regions. Eight characterized genes that are known to control inflorescence architecture in maize (Zea mays L.) and other grasses were mapped in sorghum. Cyathium may The cyathia are sometimes solitary, but are usually in cymes, inflorescences of the second order, in pseudumbels, on dichotomously branched stalks or in so-called simple cymes which consist of one central and two lateral cyathia. Inflorescences may also have classified based on Native of jower is Africa (Ethiopia & Sudan) 30. Plant Sci 168:1393–1408. Immature embryos at milk stage of endosperm, usually 1.2 to 2.5 mm long, were used for inoculation. The inflorescence of sorghum is a compact panicle. an  unbranched indeterminate inflorescence with sessile flowers.

Introduction Allelopathy is a biological process by which plants produce one or mor e biochemicals known as allelochemicals that influence the growth and survival of other plants 21. The grass inflorescence is the primary food source for humanity, and has been repeatedly shaped by human selection during the domestication of different cereal crops. Example: Cauliflower.

The inflorescence of guinea sorghums is often very open. Although our transcriptional data identified widespread molecular similarities in maize tassel and sorghum panicle development, a known regulator of determinacy, RA3, and stem cell homeostasis, TD1, are not expressed in a shared pattern during inflorescence … Torus contains two types of florets: 1. Sorghum is predominantly self-pollinated crop, in which cross-pollination ranges from 5% to 15% with an average of about 6%. grouping of flowers in one place gives a better attraction to the visiting Cold Spring Harbor Lab Press, New York, pp 81–87, Salvi S, Tuberosa R (2005) To clone or not to clone plant QTLs: present and future challenges.
