Seed yield of psNTP9 events and parental line Williams 82 (WM 82) trialed in 2016, 2017, and 2018. (a) Field trials were conducted at three different locations in the US—El Paso, Illinois; Henderson, Kentucky; and Atlanta, Indiana. Seed yield performance and analysis of psNTP9 events at each of the individual sites can be found in supplemental data. Combined site analysis over the three trials determined 5.25 bushels per acre as the value of 5% least squared difference (LSD0.05) for mean separations. Asterisk symbol (*) next to yield delta (%) inside the figure indicates significant yield difference from parental line WM 82 at p = 0.05. All data are presented as mean of eight plot replicates over three individual sites ± standard error (SE). (b) Seed yield of psNTP9 events and parental line trialed in 2017. The field trials were implemented during the counter-season seed increase at three locations in Puerto Rico. Seed yield performance and analysis of psNTP9 events at each of the individual sites can be found from supplemental data. Combined site analysis of seed yield over the three trials determined 3.91 bushels per acre as LSD0.05 value for mean separations. Asterisk symbol (*) next to yield delta (%) values inside the figure indicates significant yield difference from parental line WM 82 at p = 0.05. All data are presented as mean of fifteen plot replicates over three individual sites ± SE. (c) Seed yield of psNTP9 events and parental line trialed in 2018. The field trials were conducted at three different production regions in the US—Lawrence, Kentucky; Smithville, Missouri and Troy, Ohio. Seed yield performance and analysis of psNTP9 events at each of the individual sites can be found from supplemental data. Combined site analysis of seed yield over the three trials determined 3.30 bushels per acre as LSD0.05 value for mean separations. All data are presented as mean of twelve plot replicates over three individual sites ± SE. (d) Seed yield of psNTP9 and sibling nulls trialed in 2018. The field trials were conducted at three different production regions in the US—Lawrence, Kentucky; Smithville, Missouri and Troy, Ohio. Combined site analysis of seed yield over the three trials determined 3.30 bushels per acre as LSD0.05 value for mean separations. Asterisk symbol (*) next to yield delta (%) inside the figure indicates significant yield difference from corresponding sibling null at p = 0.05. All data are presented as mean of twelve plot replicates over three individual sites ± SE.
