Abstract

Analysis of flowering in diallel crosses involving seven varieties of peas has shown that a simple polygenic system is primarily responsible for the control of flowering, with a major gene (Sn) or effective factor which delays flowering and whose effect is increased during short days. Since there was no evidence of transgressive segregation, the use of this material in a breeding programme would not be expected to provide new varieties significantly earlier or later flowering than their parents. The development of earlier and later flowering varieties will most probably depend on the discovery of parents where a different relationship exists between node of flowering and time of flowering from that discovered during the investigation.
