Plant phenology and collection site environment in old word lupins. (A) Principal components analysis of collection site bioclimatic variables and plant phenology data from a common garden 2007 field study of L. angustifolius, L. luteus and L. albus. Factor loadings for PC1 and 2 are presented as vectors (black for bioclimatic, green for biological variables), abbreviated as follows: av, average; CV, coefficient of variation; das, days after sowing; flow, flowering; pod, podding; podfill, pod filling phase; rain, rainfall; raindays, number of rainy days; RH, relative humidity; rep, reproductive phase; seas, season; sun hours; mean daily sunshine hours; T, temperature; veg, vegetative phase. Markers represent genotype scores, classified by species and domestication status. (B) Linear regression of flowering against collection site season rainfall, fitting species as factors, accounting for 55.8% of variance. Regression equations presented in Table 5. (C) Linear regression of maturity against flowering, fitting species and domestication status as factors, accounting for 79.5% of variance. Regression equations presented in Table 5.
