Zhang Conghe et al (Anhui Winall High Technology Agricultural Research Istitute,Hefei 230031)
Guangzhan 63S was planted in Hefei from 1999 to 2000.The number of the leaf of main stem varied from 14.5 to 12.9. The period from sowing to initial heading lasted 91 to 69 days with average effective accumulated temperature of 1?058.9?℃. There was significant positive correlation between the period and the effective accumulated temperature (r=0.761 **),which showed Guangzhan 63S belonged to early-medium indica two-line core sterile line.
