Short-term biomass production of red clover (Trifolium pratense L.) and its inheritance

The objective of this study was to evaluate the short-term (one-year) biomass production in red clover and to obtain an estimate of the heritability of this characteristic. Progenies from parents with high biomass had higher biomass than those from parents with low biomass or having one parent in each category. The narrow-sense heritability estimated from mid-parent offspring regression was 0.23, from parent-offspring correlation was 0.22, and realized heritability was 0.15, indicating that progeny testing would be required for successful selection of populations with greater biomass production. Plants selected for high biomass production tended to have higher shoot:root ratios and flower more profusely than the parental checks and the low biomass plants. This indicates that by selecting for high biomass, red clover will be selected for more annual growth habit at the same time.
