随着我国棉花生产的发展,优质育种己列为重要育种目标。但在许多育种单位,由于育种材料繁多,要想对育种材料的纤维品质全面测试,难以做到。因此在优质育种上存在一定的盲目性。为了提高优质育种的自觉性,本文试图通过对棉花种质的检验,直接判断或间接估测纤维品质的优劣,为优质育种和良种繁育提供依据和方法。 一、检验方法 供试种质是1985—1986年我所种植的21个品种(系),各品种(系)的种子先经硫酸脱绒,晒干粒造,检验以下项目:子指(a);沉子比(n_1/n_2):将种质100粒种 With the development of cotton production in our country, high-quality breeding has been listed as an important breeding target. However, in many breeding units, due to the variety of breeding materials, it is difficult to fully test the fiber quality of breeding materials. Therefore, there is a certain degree of blindness in breeding. In order to improve the consciousness of high-quality breeding, this paper tries to directly judge or indirectly estimate the quality of fiber through the test of cotton germplasm, and provide the basis and method for high-quality breeding and breeding. First, the test method The test germplasm for the 1985-1986 I planted 21 varieties (lines), each variety (line) of the seeds were first plucked by sulfuric acid, dried grain made to test the following items: sub-refers to (a ); Shen sub ratio (n_1 / n_2): 100 species of germplasm
