ND280
ND280 was derived from a cross of an S0 plant from the synthetic breeding population, NDSB(FS)C3 to the related line cross (ND245xND252) via self pollination over 9 generations with concurrent selection for plant stature, plant health, ear characteristics, and leaf growth rates. NDSB(FS)C3 was developed from NDSB [Cross (1980), (Crop Sci. 20:418)] via reciprocal full-sib selection using NDSA as the tester population. Hybrids with ND280 averaged significantly higher grain yields and yield for maturity (performance index) than all other lines except ND301.
