摘  要：
据国家、新疆早熟棉区试验结果分析:“十五”期间新疆早熟中长绒棉育种取得新进展,有两个新品种通过2003~2007品种审定,在生产上示范推广,一批新品系参试。新品种(系)产量水平接近常规推广品种,纤维品质基本符合农业部2003~2007年中长绒棉育种目标,抗病性在逐步提高,同时存在熟性偏晚,吐絮不集中,中后期花成熟度差,抗逆、适应性不强等问题。提出了提高早熟性、强力和抗逆为重点的育种目标和扩大遗传背景,打破性状间负相关性及田间目标性状选择等改良措施。

摘  要：
Xinjiang is the greatest region famous for cotton production.In recent years the new development of breeding early-maturing and medium-long-wool varieties has been made.The two varieties of them have been examined and approved by Xinjiang Uygur Autonomous Region.The yield level of new species,the fiber quality of which basically services long staple cotton breeding goal from 2003～2007.Disease resistance is improved.There some problems also exist such as maturity is late,cotton maturation period is not concentrated and late cotton maturity is bad,character form is single,adverse resistance is not strong etc.Some improving measures were adopted,such as early maturity,strength and adverse resistance were regarded as main breeding goal,inheritance background was extended,the negative character correlation and character election in the field were broken.
