分析了辽宁省1949-2012年育成的95个花生品种系谱及农艺性状的演变。结果表明:辽宁花生育成品种共涉及100个亲本,其中,来自辽宁的有45个,49个是育种单位的中间材料,鲁花12号、白沙1016、伏花生、豫花11号等是辽宁花生育成品种的骨干亲本。进入21世纪以来,辽宁省育成的花生品种株高、侧枝长逐渐增加,从变异区间来看,百仁重、出米率呈增加趋势,而粗蛋白与粗脂肪含量变化较小。在分析辽宁省花生育种背景的基础上,提出辽宁省花生育种上宜重视回交手段的利用,发展食用型品种,把抗旱、抗寒、抗病、抗虫、耐连作作为重要的育种目标,利用生物技术手段和野生资源加速育种进程,进一步拓宽辽宁花生品种的遗传基础。
The pedigree and agronomic traits of 95 peanut cultivars bred from 1949 to 2012 in Liaoning Province were analyzed. The results showed that there were 100 parents of peanut cultivars in Liaoning Province, of which 45 were from Liaoning and 49 were intermediate materials of breeding units. Among them, Luhua 12, Baisha 1016, Fuhua and Yuhua 11 were Liaoning peanut Bred varieties of the backbone of the parents. Since the beginning of the 21st century, the plant height and branch length of peanut varieties bred in Liaoning Province have gradually increased. From the variation interval, the percentage of peanut kernels and rice leaves showed an increasing trend while the variation of crude protein and crude fat content was small. Based on the analysis of the breeding background of peanut in Liaoning Province, it is suggested that the priority should be given to the utilization of backcrossing methods in Liaoning peanut breeding. The edible cultivars should be developed to make drought-resistant, cold-tolerant, disease-resistant, insect- The use of biotechnology means and wild resources to speed up the breeding process to further expand the genetic basis of peanut varieties in Liaoning.
