一、前言 小麦是我区的主要冬播作物。但每年在春夏之际,时常由于降雨量过分集中而遭受不同程度的内涝灾害,尤其是沿江与滨湖地区,因地势低洼排水不良,受害更为严重。这不仅对小麦开花结实极不利,严重影响产量,也从而引起小麦面积的减少。因此,培育耐渍性较强的小麦品种,已成为本区小麦育种工作的重要任务。 I. Introduction Wheat is the main winter sowing crop in our district. However, in spring and summer each year, waterlogging disasters are often suffered due to excessive concentration of rainfall, especially in the areas along the rivers and lakes and lakes and poor drainage due to low lying areas. This is not only unfavorable to the flowering and fruiting of wheat, which seriously affects the yield but also causes the reduction of wheat area. Therefore, cultivating wheat varieties with strong stain resistance has become an important task of wheat breeding in this area.
