Fig. 2: Genotypic and allelic diversity effects.
From: Single-gene resolution of diversity-driven overyielding in plant genotype mixtures
a Illustration of the concept of General and Specific Combining Ability (GCA and SCA) derived from different genotype compositions assembled according to a competition half-diallel design. GCAs of genotypes 1 and 4 are estimated from productivities of all mixtures in which these genotypes occur, SCA1,4 denotes the estimated productivity deviation of communities containing these two genotypes after accounting for GCAs. b QTL map of allelic diversity associated with variation in SCA within genotypic mixtures. Blue and red lines denote the different chromosomes. “BRX” indicates the location of the BREVIS RADIX gene. c Boxplots showing SCA distributions of different plant stands: genotypic monocultures (mono; n = 20), genotypic mixtures but allelic monocultures at the QTL on chromosome 2 (SS; n = 66 and UU; n = 28), genotypic mixtures and allelic mixtures at the QTL (SU; n = 96). Green lines denote mean values +/− s.e.m. Boxes show interquartile ranges with medians; whiskers indicate data ranges up to 1.5 times the interquartile range from the box.
