摘　　要：小麦新品种衡观35是由河北省农林科学院旱作农业研究所选育而成,该品种有着广泛的适应性。通过对该品种发育特性的研究,明确了该品种的温光特性,揭示了其广泛生态适应性的原因。衡观35虽然是半冬性品种,但属于对温反应不敏感型品种,且感光性偏弱,对光反应较为迟钝。正是这种特性,使衡观35较好地适应了多种生态条件,其发育速度受到生态条件的影响较小;再加上其抗寒性突出、矮秆抗倒、抗病性强、节水明显和早熟等特点,综合决定了该品种对黄淮麦区(分南北两片)、长江中下游麦区和北部冬麦区4个不同的生态区域有着很好的生态适应性,这也是其适应性广泛的根本所在。The new winter wheat variety Hengguan 35 was bred by Institute of Dry Farming,Hebei Academy of Agriculture and Forestry Sciences with abroad adaptability.The developmental characteristics of the variety were studied,and the thermo-photosensitivity characteristics were determined.The results showed that it was a semi-winter variety,while it was insensitive to temperature with weak photosensitivity,and was insensitive to light,so it could fit many ecological conditions,and the ecological conditions had little influence on the development speed.It had the characteristics of strong cold resistance and disease resistance,dwarfing,lodging resistance,water saving and early maturity,so it had better ecological adaptability in Huang-huai areas（north and south）,middle and lower Yangtze,and Northern China.
