不同生态环境下陆地棉生育期及产量性状的遗传研究
Quantitative Study of Growth Period and Yield Traits in Upland Cotton (G. hirsutum L. ) under Different Ecological Environments
摘要
Abstract
The major gene plus polygene genetic rules of growth period and yield traits were analyzed using six generations of earliness variety Baimian 2 ( P2 ) and genetic standard line TM-1 ( P1 ) in upland cotton ( G. hirsutum L. ), and their F1, B1 ,B2 and F2 grown in Yellow River Valley cotton area(environment Ⅰ) and early-mature cotton area of North Xinjiang( environment Ⅱ) in China. The results were as follows: Major genes for all traits were always detected in two environments except lint percentage, the ones for which were not detected in environment Ⅱ. The optimum models of some traits including growth period, lint yield, boll weight and lint index were always same in two environments,they were E-O, D-2, E-3 and B-1, respectively; whereas the optimum models of other traits such as seed yield, lint percentage, bolls per plant and seed index were different in two environments. The genetic types of each trait between two environments were not completely same. Growth period, bolls per plant, lint index and seed index were mainly controlled by major gene or belonged to typical major gene inheritance;seed yield, lint yield, boll weight and lint percentage were mainly controlled by major gene or polygene. Single-cross recombination or simple backcross should be adopted for the traits belonged to major gene inheritance or mainly controlled by major gene, and polymerization backcross or cumulating positive alleles through recurrent selection should be adopted for the traits mainly controlled by polygene.关键词
