Other claims from this paper (5)

Association Soybean genetic gain increased yield by 0.49 bu/a/year.
Mechanism Increases in seed number mainly explained soybean yield gain, rather than seed weight.
Intervention effect Nitrogen application increased soybean yield equally across genotypes.

Other claims from this paper (12)

Observation No abnormalities were detected in 78 plants regenerated after the first culture period.
Observation In the second period, 91 of 189 regenerated plants were cytologically abnormal.
Observation The researchers detected 108 aberrations.
Observation Most aberrations, 96%, involved chromosome structure.
Observation Interchanges comprised 42% of structural aberrations.
Observation Heteromorphic pairs comprised 19% of structural aberrations.
Observation All deficiencies were intercalary.
Observation Most interchanges, 51%, involved chromosome 6.
Association Male sterility factors were not associated with chromosome instability.
Observation Breakpoints were primarily on chromosome arms with large heterochromatin blocks such as knobs.
Observation Several plants from one culture apparently shared identical aberrations, suggesting one originating event.
Mechanism The findings support a role for heterochromatin in chromosome breakage during culture.
