Variation and relationship between seed vigour and yield in rice (oryza sativa L)

Seeds of 24 West African rice (Oryza sativa L.) genotypes were evaluated for seed vigour traits in the laboratory and field in the late cropping season of 2003 and early cropping season of 2004 at the Research Farm of University of Agriculture, Abeokuta, Nigeria. Seed yield of these genotypes were also determined in the field during the two seasons. The laboratory study was carried out in a completely randomized design, while the field tests were laid out in a randomized complete block design each with three replications.
