以石家庄市农林科学院新育成的3份棉花新品系为试验材料,选用河北省目前主栽品种为对照进行产量比较试验。结果表明:参试的3个棉花材料中,M1品系产量表现比较突出,M2和M3性状表现突出。建议表现优良的M1品系参加区域试验,优良性状品系M2和M3继续选种。 Taking 3 new cotton lines newly bred by Shijiazhuang Academy of Agriculture and Forestry Sciences as tested materials, the main cultivars in Hebei Province were selected as the control to compare yield. The results showed that among the three cotton materials tested, the yield of M1 strain was more prominent and the M2 and M3 traits were outstanding. It is suggested that the M1 line with excellent performance should participate in the regional test, and the M2 and M3 line with excellent characters should continue to be selected.
