Li Yajuan; Cui Chenghuan (Norheast Agricultural University, Harbin, 150030 PRC)
A planting experiment at different dais for 6 varieties and a cultivating experiment or 5varieties at different locations were conducted to investigate the of effect of temperature at grain filling period on the rice quality. The effect of temperature at filling period on the rice quality varied with varieties and qualify fraits. Among the varieties. Mudanjiang 17 was susceptible,while Dongnong 416 was in susceptible to the temperature. And the chalky rice area. A.mylose content and qelatination consistency were likely affected, while the shape and qelatination milled rice ratio were not significontly affected by the temperature at filling period. Temperaure during filling period had negative conclation with Amyloe content Gelatination temperature, shape, brown rice ratio. milled rice ratio and head rice ratio, and posihve correlation with chalky rice percentage. chalky rice and Gelatinatlon consistency.
