建国以来,我国自育品种已在生产上发挥主导作用,靠引种美棉的历史已经结束。由于自育品种的迅速普及推广,对我国棉花增产起了很大作用。1982年全国棉花总产达到7,196.9万担,亩产皮棉83.32片,总产居世界产棉国第一位。1983年棉花总产达到9,000万担,处于世界产棉国领先地位,自给有余,还可出口,它标志着我国棉花育种工作进入了一个新的阶段。自育品种的早熟性、丰产性、抗逆性好,纤维品质有所提高,品级也较好,但内在质量与外来品种比
Since the founding of the People’s Republic of China, the self-breeding varieties in our country have played a leading role in the production. The history of introducing cotton by the United States has ended. Due to the rapid popularization and promotion of self-breeding varieties, it has played a significant role in the increase of cotton output in our country. In 1982, the total output of cotton in the country reached 71.969 million, 83.32 mu of lint per mu, and the total output was the first place among the cotton producing countries in the world. In 1983, the total output of cotton reached 90 million, a leading position in the cotton producing countries in the world. It is self-sufficient and exportable. It marks that cotton breeding in China has entered a new stage. Self-breeding varieties of early maturity, high yield, good resistance, fiber quality has improved, the grade is also better, but the intrinsic quality and exotic varieties than
