Yield Stability Analysis of Spring Wheat Varieties with Different Reactive Characteristics to Photoperiod and Temperature

Xin Wenli; Xiao Zhimin; Qi Shiyu and Wang Shien(Crop Breeding Institute of Heilongjiang Academy of Agricultural Sciences)  
In cider to ascertain the ralationship between reactive characteristics to Photoperiod and temperature and yield stability of spring wheat varieties in Heilongjiang Province,yield Stabilities of 8varieties in 4 main type were evaluated synthetically in this paper. The results showed that the yield stability of photasensitive varietics was better than that of photoinsensitive varieties and temperature insensitive varieties had better stability than temperature - sensetive varieties. In the meantime,it was pointed out that the first decitive factor of the yield stability of spring wheat varieties is sensitive degree of the vaneties to Photoperiod and second decisive factor is the sensitive degree to temperature. The order of yield stability in varieties of 4 type was: Photosensitive and temperature - insensitive typephotasensitive and temperature - sensitive typephptoinsensitive and temperature - insensitive typephotoinsensitive and temperature - sensitive type.
