“…Further examples are described in Marantaceae (Van Huylenbroeck et al, 2018) [19] Asclepias sp. (Lewis et al, 2021) [12] , Pavonia (Yue and Ruter, 2021) [25] , and various additional crops. In order for successful interspecific or extensive intergeneric crossing within a specific genus to occur (Eeckhaut et al, 2006) [31} , a number of hurdles must be overcome.…”

Plant breeding for crops and ornamentals has grown in importance over the past century. Mendel's theories about the inheritance of characteristics established the groundwork for contemporary genetics. While chromosomal duplication, mutation breeding, and intra-and interspecific cross-breeding remain the mainstays of ornamental plant breeding, plant breeding has advanced dramatically since Mendel's day. Advanced accuracy breeding and selection towards more challenging to measure or quantify characteristics are now possible because to new genomic techniques. The breeding of ornamental plants nowadays is a challenging endeavor with constantly evolving and new obstacles. Collaborations between research and industry will be necessary to apply current technology to small-scale crops.

During the last century, plant breeding of crops and ornamentals has become an important business. Mendel’s principles of inheritance of traits laid the foundation of today’s modern genetics. Although intra- and interspecific cross breeding, chromosome doubling and mutation breeding still form the cornerstone of ornamental plant breeding, the speed of plant breeding has significantly increased since Mendel’s time. New genomic tools now offer possibilities for advanced precision breeding and selection towards more difficult to assess or quantitative traits. Today’s ornamental plant breeding is a complicated exercise, characterized by new and rapidly-changing challenges. Partnerships between industry and research will be essential to implement available technologies in minor crops.

Prediction Model for Breeding Hardy Geraniums

Key message. The success of interspecific hybridization in hardy geranium (Geranium sp.) can be predicted by considering the genetic distance between parental genotypes and using the logistic regression model developed in this study. Hardy geranium is a popular ornamental plant known for its architecture, hardiness, prolonged flowering, and diverse colors in leaves and flowers. In ornamental breeding, the pursuit of novel trait combinations is never-ending. Even in Geranium, certain combinations of valuable traits have not yet been achieved. Interspecific hybridization can increase diversity; however, success remains low due to pre- and postzygotic barriers. Crossing success can be predicted by response criteria such as pollen tube growth (tube_length), seed development (seed_dev), and seed setting (seed_set). Within a collection of 42 Geranium genotypes and during two consecutive breeding seasons (years), we evaluated tube_length, seed_dev, and seed_set for 150, 1155, and 349 crosses, respectively. These crosses varied in four parental differences (variables): chromosome number (Chrom), DNA/chromosome (DNA), style length (Style), and genetic distance expressed as the Jaccard distance (cJaccard = 1 − Jaccard). Using logistic regression models has confirmed that most often, the success rate decreased with increasing parental distance. The most consistent association was seen in seed_dev in combination with cJaccard. The model was used to predict the number of crosses necessary to have 10 successful crossing products by taking into account the uncertainty in the model. These findings provide valuable guidance for future planning of interspecific breeding experiments in Geranium. By incorporating the genetic distance between parental genotypes, breeders can enhance the efficiency and success of hybridization efforts.
