Other claims from this paper (12)

Observation All F3 wheat traits showed significant genotypic variation.
Observation Broad sense heritability of F3 wheat traits was generally moderate to high.
Observation The progeny main effect on grain yield was highly significant.
Intervention effect No progeny line significantly outyielded the best parent for grain yield.
Association F3 plant height was negatively correlated with progeny grain yield (r= -0.31 to -0.50).
Association F3 kernel weight was negatively correlated with progeny grain yield (r= -0.03 to -0.44).
Association F3 harvest index was positively correlated with progeny grain yield (r = 0.18 to 0.5 l).
Association F3 spike number was positively correlated with progeny grain yield (r=0.08 to 0.40).
Intervention effect Retrospective F3 selection at 25% intensity increased population mean yield by 0 to 12%.
Intervention effect Retrospective F3 selection doubled the proportion of high yielding lines in some cases.
Mechanism The ineffectiveness of F3 selection is suggested to be largely due to genotype by environment interaction.
Recommendation Only selection in F3 for reduced stature is considered worthwhile for advancing wheat yield potential.

Tetsuo Hara; Yoji Sonoda Soil Science & Plant Nutrition 1981. doi:10.1080/00380768.1981.10431270

Other claims from this paper (11)

Intervention effect Increasing nitrogen supply from 5 to 50 ppm N increased cabbage plant dry weight.
Intervention effect Nitrogen supply at 500 ppm N decreased cabbage plant dry weight.
Intervention effect Cabbage grown at 50 ppm N had the highest sugar content.
Intervention effect Cabbage grown at 50 ppm N had the highest rate of 14CO2 assimilation.
Mechanism Growth at 50 ppm N explains efficient cabbage-head development through the highest sugar content.
Mechanism The decrease in cabbage dry weight and head yield under low light is attributed to lower sugar content and lower 14CO2 assimilation.
Intervention effect Low light intensity made the 15NO3-N uptake by cabbage smaller than high light intensity.
Intervention effect Low light impaired incorporation of 15N into the 80% ethanol-insoluble fraction of the cabbage head.
Association The later the growth stage at which 14CO2 was assimilated, the greater the 14C-retention percentage at harvest.
Association The later the growth stage at which 14CO2 was assimilated, the greater the distribution of 14C into the cabbage head.
Association The 14C-retention percentage decreased with increased nitrogen supply or decreased light intensity in cabbage.
