Abstract
Tropical lines of Phaseolus spp. planted in Hawaii in spring or early summer included types which bloomed in the usual 30-45 days and types which did not bloom until days had begun to shorten in the fall. Short day types bloomed at daylengths between 113/4 and 131/4 hr, with the majority blooming between 121/2 and 13 hr. P. vulgaris, P. lunatus, and P. calcaratus included both short-day and day-neutral types. All lines of P. aconitifolius, P. acutifolius, and P. angularis were day-neutral. Single lines of P. erythroloma and P. cf. stenolobus were short-day, and single lines of P. pilosus, P. radiatus, and P. bracteatus were day-neutral.Keywords
