2017-2021年东北核心产区谷子品种联合鉴定试验-参试品种区域适应性及主要性状分析

Breeding Changes and Main Traits Analysis of Core Millet Producing Areas in Northeast China from 2017 to 2021——Regional Adaptability and Main Character Analysis of Test Varieties

利用2017-2021年东北核心产区谷子品种区域适应性联合鉴定试验数据结果,对各试点产量表现以及所有参试品种的主要农艺性状和产量表现进行比较分析,并对通过鉴定的品种做进一步分类分析。结果表明,参试品种表现出较强的地方区域性,区域适应性还应进一步提高。5年间谷子新品种产量潜力受稳产性和适应性等方面影响没有突破性表现;在主要农艺性状方面,进一步提高单穗重和穗粒重还是东北核心产区谷子选育的主要方向。对于通过鉴定的品种而言,基本达到了降低株高的目标,但与产量相关的农艺性状提升并不明显,这可能与目前谷子生产上更注重品质提升,并不只是追求产量的趋势有关。5个谷子系列在主要农艺性状上存在差异显著性,地方品种的育种偏向性明显,与其相应的地区生产偏向一致。

Based on the results of the joint identification test of regional adaptability of millet varieties in the core producing areas of Northeast China from 2017 to 2021,the main agronomic traits and yield performance of all tested varieties were compared and analyzed,and the 18 varieties that passed the identification were further analyzed and classified.The results showed that the tested varieties showed strong local regionalism,and regional adaptability should be further improved.Yield potential performance of new millet varieties was affected by stable yield and adaptability during the five years,and no breakthrough was found.The main direction of millet breeding in the core producing areas of northeast China was to further increase the weight of single panicle and grain per panicle.The goal of reducing plant height was basically achieved,but the improvement of agronomic traits related to yield was not obvious,which may be related to the trend of paying more attention to quality improvement in millet production than the pursuit of yield.The five millet series showed different differences in main agronomic traits,and the breeding bias of local varieties was obvious,which was consistent with the corresponding regional production bias.
