The types of response to photoperiod and temperature of eleven PGMR lines provided by 863-101m01 of a special subject identified by artificially controlled photoperiods and sowing/transplant under natural conditions in Wuchang in 1991. The photoperiod/temperature factors and their critical indices which affect fertility change of these PGMR were primitively verified. Rusults showed that the fertility change of all the PGMR were controlled by photoperiod and temperature,and the pure PGMR and TGMR materials not exist. Agrometeology basis is provided for seleting and breeding PGMR of ecological adaptability field.
