Identification of Soybean Genotypes in Wide Rows for Use in NClI'row-row Culture
Thirty lines and six cultivars of soybeans (Glycine max (L.) Merr.) were evaluated in wide-row (76 em) and narrow-row (18 cm)spacingsat two locations in 1982 and one in 1983. The objective of the study was to determine if evaluation of lines in wide rows can be used to identify superior linesfor...

| Summary: | Thirty lines and six cultivars of soybeans (Glycine max (L.) Merr.) were evaluated in wide-row
(76 em) and narrow-row (18 cm)spacingsat two locations in 1982 and one in 1983. The objective of the
study was to determine if evaluation of lines in wide rows can be used to identify superior linesfor
narrow-row culture. Yield in narrow rows was 27.0% higher than wide rows at both locations in 1982
and 20.8% higher in 1983. In general, the high yielding entries in wide rows were also the highest yielding
ones in narrow rows, although they did not necessarily include all the highest yielding ones in narrow
rows. One cultivar and two lines were, however, consistent in exhibiting a moderate to high response to
narrowing of row spacing, over years and locations. No trait was identified as being associated with the
response. In general, selection of lines superior in wide row nurseries will identify lines that will perform
best in narrow-row culture. |
