Study on Breeding of Maize Hybrid Xinyu34 with High Starch Content

Mid-late mature Maize hybrid Xinyu34 was developed by Institute of Grain Crops,Xinjiang Academy of Agricultural Sciences,with new inbred line Xinzi534 which was developed by the institute as female parent and introduced line Chang72 as male parent in 2001.It was released by Xinjiang Crops Variety Releasing Committee in 2006.It obtained high and stable yield,strong resistance and good grain quality in Xinjiang Maize Regional Experiment and Production Experiment during 2004～2005.It can be used as both grain and fodder.It obtained the yield aroud 894.9 kg/667m2,increased by 4.78% compared with Zhengdan958.The content of crude protein,starch and kernel density is up to 11.0%,76.36% and 788 g/L,respectively,which surpassed National first class standard of feed and high starch maize respectively.It is the specific maize hybrid for starch processing.It is adaptable for planting in the north of Xinjiang above 10℃ effective temperature over 2 800℃
