| 摘 要： | 为了研究小麦育种的高产途径,此试验以大穗型(01-35),中间型(62008,4133-2)和多穗型(02-48)高产小麦品种为实验材料,在大田条件下,研究了小麦植株和籽粒可溶性糖含量变化及干物质积累动态。结果表明:不同类型的品种植株、籽粒可溶性糖含量变化与其地上部分及籽粒干物质积累速率和积累总量有密切关系。就群体而言,多穗型品种地上部分干物质积累量最多,产量也最高,中间型次之,大穗型最低。大穗型品种具有较强的营养物质外运能力,其千粒重最高,多穗型次之,中间型最低。充分协调源库流的关系,选育出大穗型和多穗型相结合的、综合农艺性状更佳的品种,将实现小麦高产、优质、高效的育种目标,从而更好地服务于大田生产。

| Abstract: | With the purpose of studying the way of high yield in wheat breeding,the experiment has been conducted to the changes of soluble sugar contents in plant and kernel with the relationships of their dry matter accumulation in different high yielding wheat genotypes.Using the large-ear(01-35),middle-ear(62008,4133-2)and many-ear(02-48)wheat genotypes.The results showed that soluble sugar contents in plant and kernel are closely related with dry matter accumulation and totle accumulation weight.In the view of group situation,many-ear cultivar had the most plant dry matter accumulation and yield,middle-ear and large-ear cultivars in orders.The plant of large-ear cultivar during kernel filling stage maintained stronger translation of fertilizer matters,so 1000-kernel dry weight is the highest,the second one is many-ear cultivar and the last one is middle-ear cultivar.Adequatly coordinate the relationships of metabolic source,metabolic pool and metabolic stream,combine large-ear with many-ear genotypes and breeding better agriculty properties of vaities wheat.Therefore,we can successfully accomplish the goal of wheat breeding-high yield,high quality and high efficiency.By then,we can more efficiency to serve grain producing bace. |
