- Abstract
This article presents information about the newly registered two germplasm lines of maize, designated as BSLE(M-S)C30 and BSLE(M-L)C30. Registration numbers and PI numbers of these germplasm linee are:GP-401, PI 636503 and GP-402, PI 636502, respectively. These maize populations were developed after 30 cycles of divergent mass selection for ear length by the Iowa Agriculture and Home Economics Experiment Station. Both populations originated from Iowa Long Ear Synthetic, which was developed by intermating 12 inbred lines with above-average ear length. BSLE(M-S)C30 is a strain of BSLE developed after 30 cycles of mass selection for reduced ear length. Average ear length decreased 0.37 cm cycle-1 of mass selection during 27 cycles of selection. BSLE(M-L)C30 is a strain of BSLE developed after 30 cycles of mass selection for increased ear length. Average year length of BSLE(M-L)c27 increased 0.27 cm cycle-1 of mass selection. Both these germplasm lines, reportedly, are significantly different from each other for ear length and other plant and ear traits, and both populations are significantly different from BSLE, the original population, for all traits except for grain yield of BSLE and BSLE(M-L)C27.
