解放以来,在毛主席革命路线指引下,我区棉花系谱育种工作取得了一定成绩。我所采用系谱育种法先后育成了“徐州209”、“徐州1818”、“徐州1214”、“徐州287”、“徐州58”和“徐州142”等棉花新品种,其中“徐州209”曾在黄淮流域棉区推广400多万亩,“徐州1818”和“徐州1214”两个品种,到1972年已推广1,000多万亩,促进了棉花增产。系谱育种是在现有的品种群体内,利用选择变异、结合培育而较快地获得新品种的一种简便易行的方法。棉花天然杂交率较高,一般经天然杂交和自然选择而保留下来的优良棉株,个体的遗传性比较稳定,较能适合于当地自然条件,丰产性能也较为突出。实践使我们体会到,必须针对当前生产中存在的问题,正确确定系谱育种的主要目标(我们以丰产、早熟和出苗好为主要目标);搞好三个相结合,即领导干部、工人和科技人员相结合,育种、试验示范和推广相结合,育种、
Since the liberation, under the guidance of Chairman Mao’s revolutionary line, certain achievements have been made in cotton genealogy breeding work in our district. The pedigree breeding method of “Xuzhou 209”, “Xuzhou 1818”, “Xuzhou 1214”, “Xuzhou 287”, “Xuzhou 58” and “Xuzhou 142” More than 4 million mu of “Xuzhou 1818” and “Xuzhou 1214” were popularized in the cotton belt of Huang-Huai River valley. By 1972, more than 10 million mu of cotton was promoted, which boosted the cotton yield. Pedigree breeding is an easy and convenient way to get new breeds faster with selection mutation and cultivating within the existing breed groups. Cotton has a high rate of natural hybridization. The fine cotton plants are generally preserved by natural hybridization and natural selection. The individual’s heredity is relatively stable, more suitable for local natural conditions and high yield performance is also outstanding. Practice has led us to realize that we must correctly identify the main goals of pedigree breeding (we focus on high yield, early maturity and good emergence) in light of the problems in current production. We should do a good job combining the three, namely leading cadres, workers and science and technology Combination of personnel, breeding, pilot demonstration and promotion of combining breeding,
