Potential for Marker-Assisted Simultaneous Improvement of Grain and Biomass Yield in Triticale
BioEnergy Research, 2017Co-Authors: Wenxin Liu, Willmar L. Leiser, Sigrid Weissmann, Hans Peter Maurer, Matthew R Tucker, Volker Hahn, Tobias WürschumAbstract:Triticale is a promising crop for agricultural Biomass production but breeding has until now mainly focused on grain Yield. Here, we evaluated the potential of marker-assisted simultaneous improvement of grain Yield and Biomass Yield. To this end, we employed a large triticale doubled haploid population with 647 individuals derived from four families that were phenotyped for grain Yield and Biomass Yield, as well as thousand-kernel weight, tiller density, and plant height in multi-environment field trials. Employing an association mapping approach, we identified quantitative trait loci (QTL) for all the five traits. The phenotypic correlation between grain Yield and Biomass Yield was low, and we detected only one overlapping QTL suggesting different genetic architectures underlying both traits. Our results indicate that a marker-based selection for either grain Yield or Biomass Yield does not adversely affect the other traits. Furthermore, an improvement of the multiplicative Yield traits can to some extent also be achieved by selection for QTL identified for the component traits. Taken together, our results suggest that marker-assisted breeding can assist the establishment of dual-purpose triticale cultivars with high grain and Biomass Yield.

Genetic dynamics underlying phenotypic development of Biomass Yield in triticale
BMC Genomics, 2014Co-Authors: Manje Gowda, Jochen C. Reif, Elmar A. Weissmann, Hans Peter Maurer, Arno Ruckelshausen, Volker Hahn, Tobias WürschumAbstract:Background The nature of dynamic traits with their phenotypic plasticity suggests that they are under the control of a dynamic genetic regulation. We employed a precision phenotyping platform to non-invasively assess Biomass Yield in a large mapping population of triticale at three developmental stages.

Hybrid breeding for Biomass Yield in winter triticale: I. Hybrid performance, trait correlations and heterosis
Plant Breeding, 2016Co-Authors: Dominik Losert, Sigrid Weissmann, Hans Peter Maurer, Tobias Wü RschumAbstract:Triticale (×Triticosecale Wittmack) holds great potential as a source for Biomass production for industrial applications in Central Europe and hybrid breeding in particular appears promising owing to the higher vigour of hybrids compared to lines. In this study, a set of 178 winter triticale genotypes, including 91 hybrids, their 10 male and 23 female parental lines, as well as 54 varieties were evaluated for Biomass Yield and other agronomically relevant traits in 2 years at five locations in Germany. We observed a large variation of dry Biomass Yield as well as significant genotypic variances and high heritabilities for all traits. For the hybrids, a moderate correlation was observed between Biomass and plant height and between Biomass and grain Yield. Mid-parent heterosis of Biomass Yield ranged from −13.6 to 16.5% with an average of 4.8%, and the maximum commercial heterosis was 9.1%. Taken together, our results illustrate the potential of hybrid breeding of triticale for Biomass Yield to diversify our portfolio of crops for Biomass production.

Potential for simultaneous improvement of grain and Biomass Yield in Central European winter triticale germplasm
Field Crops Research, 2011Co-Authors: Manje Gowda, Jochen C. Reif, Volker Hahn, C. Friedrich H. Longin, Katharina V. Alheit, Hans Peter MaurerAbstract:Winter triticale, an abundant Biomass source for producing biogas in Central Europe, has been bred until now for increased grain Yield but not for early Biomass Yield. Therefore, our objectives were to assess the feasibility of breeding triticale for simultaneous improvement of early Biomass and grain Yield as well as to predict the early Biomass Yield using an index of traits measured at maturity stage. A representative sample of 100 triticale lines was evaluated in Experiment I at four locations in Germany. Traits were measured at two growth stages (early dough and full maturity). Genetic variances were significantly different from zero for all traits. The correlated response for early Biomass Yield estimated from grain Yield (0.53) was high, which points to the efficiency of indirect selection. A multiple regression model was developed to predict early Biomass Yield. The reliability of the model was confirmed in an independent Experiment II with 49 lines. The calibration model explained 55% of total variation for early Biomass Yield. This clearly underlines that at least during earlier stages of selection, field testing can be carried out for grain Yield and related traits to select potential genotypes with high Biomass Yield based on the developed regression model.

Simple and rapid methods to evaluate methane potential and Biomass Yield for a range of mixed solid wastes
Bioresource Technology, 2009Co-Authors: Palanisamy Shanmugam, Nj HoranAbstract:This paper describes rapid techniques to evaluate the methane potential and Biomass Yield of solid wastes. A number of solid wastes were mixed to provide a range of C:N ratios. Empirical formulae were calculated for each waste based on the results of chemical analysis and these formulae were used to estimate the COD equivalent and stoichiometric methane potential (SMP). The actual COD and biochemical methane potential (BMP) were determined experimentally for each waste and for both parameters there was a good agreement between the empirical and experimental values. The potential of adenosine triphosphate (ATP) to act as an indicator of Biomass Yield (mg VSS mg-1COD removed) was determined during the anaerobic digestion process. The Biomass Yield determined from ATP analysis was in the range 0.01-0.25 mg VSS mg-1COD removed which corroborated well with previously reported studies. Empirical formula based SMP together with ATP measurement were shown to provide rapid methods to replace or augment the traditional BMP and VSS measurements and are useful for evaluating the bioenergy and Biomass potential of solid wastes for anaerobic digestion. © 2008 Elsevier Ltd.

The Biomass Yield determined from ATP analysis was in the range 0.01–0.25 mg VSS mg −1 COD removed which corroborated well with previously reported studies.
