AWOPETU, J. A., 1988. Comparison of flowering time and embryogenesis in Spanish and Portuguese populations of Lupinus albus L. (Leguminosae). Investigations were carried out on flowering-time, leaf or node number on the primary stem and embryo morphogenesis in 16 land races of Lupinus albus collected from the Iberian peninsula, using ‘Kali' and ‘Kievskij Mutant' as early-flowering reference cultivars. Observations showed that none of the Spanish or Portuguese introductions equalled ‘Kali' and ‘Kievskij Mutant' with respect to earliness in flowering and low leaf or node number, as well as shorter rate of embryo development and eventual pod maturation. However, genetic variability was established within the land races to indicate intermediate and late-flowering types that could respond to selection for eventual adaptation to central and northern Europe.
