A Study on the Parameter in Patterned Selective Cultivation of Cross-bred Cotton of High-yield and Good Quality

摘要

Canonical correlation analysis has been carried out on the 17 cross-bred cotton varieties' yield and yield forming elements, bearing state, antivirus characters and fiber quality characters to nail down the correlations among every character. Accordingly, the parameter of lint yield at 1500～1725 kg/hm2 is bettered in patterned selective cultivation of good quality cross-bred cotton. At last a discussion has been made on the organic relations and harmonious development among all the characters.
