Floral biology and Breeding System in Kodo millet (Paspalum scrobiculatum
Dr V Manimozhi Selvi
Abstract
Abstract Kodo millet belong to group of small millets and family Poaceae. Flower opening in this crop is cleistogamous type, in which explains the complete absence of natural crossing in it. Hence, self pollination highly predominates. The flowers, flowering, panicle arrangement and floral morphology of kodo millet are not clearly understood botanically. The knowledge of floral structure, floral biology, pollination behaviour and breeding techiniques are pre-requisite for understanding the system and its manipulation for creating variability, which is largely lacking in small millets. The present investigation deals with the origin, floral morphology, anthesis and pollination, breeding behavior, breeding methods and maintenance breeding of kodo millet. Keywords: Floral biology; Flowering mechanism; Reproductive biology; Hybridization; Maintenance breeding
