Under a low N level (N-0) the parental lines had a lower average mean rate for dry matter accumulation, but a slightly longer duration than that of the mutants. However, under a high N level (N-1) the mutants lines showed a 4 reduction in seed weight compared with the parental lines. No significant differences were found among the lines in their rate of N accumulation, suggesting that carbohydrates rather than nitrogenous compounds are the crucial determinant of N concentration in the seeds. It is inferred that in the same line it may be possible to achieve either a higher grain yield with lower yield with a correspondingly higher protein percentage.
