高粱不育系３１９７Ａ、Ｔｘ６２２Ａ引入承德，是冀北山区高粱育种史上的一个里程碑。促使高粱育种从品种间杂交选育向杂种优势利用转变。承德市农科所通过对高粱不育系３１９７Ａ、Ｔｘ６Ａ的利用和改良，选育出了承３Ａ、承１６Ａ等优良不育系，育出了冀承杂１、２、３、４号，冀承５号等一批高产矮秆大穗型杂交高粱新品种。为冀北山区发展旱作农业提供了更新换代品种，提高了单产，改善了品质，同时丰富了高粱种质资源。
The introduction of sorghum male sterile lines 3197A and Tx622A into Chengde is a milestone in the history of sorghum breeding in northern Hebei. Promote the transformation of sorghum breeding from hybrid breeding to heterosis utilization. Through the utilization and improvement of sorghum CMS line 3197A and Tx6A, Chengde Agricultural Science and Technology Branch selected the excellent CMS lines such as 3A, 16A and so on, 5 and a number of high yield dwarf big spike hybrid sorghum new varieties. For northern Hebei mountainous areas to develop dry farming provides replacement varieties, improve yield, improve the quality, and enrich sorghum germplasm resources.
