Other claims from this paper (10)

Association In male-sterile seeds of SS1 and SS2, protein concentration decreased linearly across selection cycles.
Association Oil concentration increased in male-sterile seeds of SS1.
Association In male-sterile seeds of SS3, protein and oil concentration showed no change.
Association In male-fertile seeds of SS1 and SS2, protein concentration decreased.
Association In male-fertile seeds of SS1 and SS2, oil concentration increased.
Association In male-fertile seeds of SS3, protein and oil concentration were unchanged.
Association On a weight-per-seed basis, protein and oil concentration increased linearly in MS and MF seeds of all three subpopulations.
Association Total protein increased only in SS3.
Association Total oil increased in SS2 and SS3.
Recommendation Selection as practiced in this study can be useful to improve protein and oil traits in soybean.

Other claims from this paper (9)

Intervention effect Irradiation at meiosis had the strongest effects in the treatment year.
Intervention effect Irradiation at tillering had comparatively small effects, attributed to counterselection.
Association Mutation yield per irradiation unit decreased with increasing dose.
Intervention effect Meiosis irradiation produced comparatively many mutants, mostly affecting seed set.
Intervention effect Spike-emergence irradiation mostly produced fertility-affecting mutations, less so than meiosis irradiation.
Intervention effect Mutation yield per unit radiation at spike emergence did not decline in the same way as at tillering and meiosis.
Intervention effect Selection against induced changes was less pronounced after spike-emergence treatment.
Intervention effect The proportion of mutations preserving fertility was greater after spike-emergence than meiosis irradiation.
Recommendation The authors prefer spike-emergence irradiation methodologically and practically.
