吉林省玉米地方品种,目前生产上多数已不再应用,但从当地的“铁岭黄马牙”、“英粒子”、“桦甸红骨子”选出的一批骨干自交系,组成了我省杂交种的当地种质基础,保证了杂交种的适应性。随着生产的发展,产业结构的调整,玉米育种目标由高产转向高产优质协调发展,转向多用途玉米品种的培育。而子粒用途不同,对其化学成分的要求就不同。因此,我们对吉林省地方品种子粒的化学成分进行了研究,以便从中筛选出相应的种质供选育适应我省特定农业生态条件的多用途玉米品种。
Jilin Province, the local varieties of corn, most of the current production is no longer applied, but from the local “Tieling Huangmaya”, “British particles”, “Huadian Redbone” selected a number of key inbred lines, formed me Provincial germplasm based on hybrids to ensure the adaptability of hybrids. With the development of production and the adjustment of industrial structure, the goal of maize breeding shifted from high-yielding to high-yielding and high-quality coordinated development and turning to the cultivation of multipurpose maize varieties. The use of different grains, the chemical composition of the requirements are different. Therefore, we studied the chemical composition of grain in Jilin Province in order to select the corresponding germplasm for selection of multi-purpose corn varieties adapted to the specific agro-ecological conditions in our province.
