俄罗斯和乌克兰饲用高粱的引进及其在黑龙江省的利用

摘要

For the purpose of enriching the forage sorghum recourse, the main agronomical characters of forage sorghum introduced from Russia and Ukraine were evaluated. The results showed that these varieties growth duration near or earlier than the varieties in Heilongjiang,and had many superior characters such as strong tillering ability, high yield per plant, high sugar content and high aftermathing qualities. These introduced varieties would play an important role in germplasm improvement and hybrid breeding of forage sorghum.%为丰富黑龙江省饲用高梁资源类型，对从俄罗斯和乌克兰引进的饲用高梁品种资源进行了主要农艺性状的鉴定。结果表明：与黑龙江省饲用高粱相比，俄罗斯和乌克兰品种的生育期相近或略早，且分蘖多、单株产量高、含糖量较高、再生能力强，具有许多原有材料所不具备的优异性状，可在今后的育种中重点利用，在饲用高梁的品种改良和杂交种选育中发挥重要作用。
