Abstract: By using Sumai6 as material,at three different latitude zones in Jiangsu(the latitudes ranges from 31.3°Nto 33.4°N), set up seven sowing date treatments,the effects of latitudes and sowing date on the starch viscosity characteristicswere studied using fast viscosity analyzer(RVA).The results indicated that :Latitude and sowing date had remarkableeffect on the starch viscosity characteristics,the effect of latitude was larger than the effect of sowing date ;With increasingof the latitude,peak viscosity and breakdown increased,the others were different ;With the delay of sowing dates ,peak viscosity,hot viscosity,breakdown,cool viscosity and setback were increased ;The starch viscosity characteristics ofdifferent latitude were different in sowing dates.
