“…Breeders commonly use locally adapted, domesticated germplasm (often called landraces) that exhibit exceptional performance in a specific group of geographic or management conditions, as well as international germplasm that are adapted to and have been selected for a wide range of environmental conditions (Hallauer et al, 1988;Lynch and Walsh, 1998;Doebley, 2004;Acquaah, 2012;Butruille et al, 2015). Locally adapted germplasm contain agronomic characteristics required for high yields in their environment and meet regional consumer preferences; therefore, they may be used more easily within a breeding program for their geographically distinct region.…”

“…Hybrids usually show dramatic improvements over the inbred lines due to heterosis (Hallauer et al, 1988;Doebley, 2004;Schnable et al, 2009;Springer et al, 2009;Acquaah, 2012). Some crops, such as maize, have well-identified heterotic pools, making it easier to know which inbred line combinations tend to give superior hybrids.…”

“…and devising strategies to combine these characteristics to obtain superior varieties (Acquaah, 2012). In its simplest form, plant breeding results in improved crop varieties (the commercial product, also referred to as cultivars or hybrids, depending on the crop) through the mating of two or more parental lines that contain desirable characteristics.…”

Bringing New Plant Varieties to Market: Plant Breeding and Selection Practices Advance Beneficial Characteristics while Minimizing Unintended Changes

Commercial‐scale plant breeding is a complex process in which new crop varieties are continuously being developed to improve yield and agronomic performance over current varieties. A wide array of naturally occurring genetic changes are sources of new characteristics available to plant breeders. During conventional plant breeding, genetic material is exchanged that has the potential to beneficially or adversely affect plant characteristics. For this reason, commercial‐scale breeders have implemented extensive plant selection practices to identify the top‐performing candidates with the desired characteristics while minimizing the advancement of unintended changes. Selection practices in maize (Zea mays L.) breeding involve phenotypic assessments of thousands of candidate lines throughout hundreds of different environmental conditions over many years. Desirable characteristics can also be introduced through genetic modification. For genetically modified (GM) crops, molecular analysis is used to select transformed plants with a single copy of an intact DNA insert and without disruption of endogenous genes. All the while, GM crops go through the same extensive phenotypic characterization as conventionally bred crops. Data from both conventional and GM maize breeding programs are presented to show the similarities between these two processes.

“…Despite its importance, the yield and quality of sorghum are constrained by a range of biotic and abiotic factors. Nevertheless, abiotic stresses remain the greatest constraints of crop production with approximately 70% estimated yield reduction (Acquaah, 2007).…”

Sorghum bicolor L. is an important crop in many tropical regions, yet it has received little attention in applying modern biotechnologies for improvement due to transformation difficulties. Drought is among the most important factors limiting sorghum productivity. The Nicotina Protein Kinase 1 (NPK1) gene confers tolerance to adverse environmental conditions. The present work was conducted to determine the amenability of sorghum genotypes to Agrobacterium-mediated transformation with the NPK1 gene and to characterize the role of that gene in S. bicolor. The NPK1 gene along with the bar gene was successfully introduced into two sorghum genotypes: Dorado and SPGM94021. The transformation frequencies were 1.49 and 1.79% for Dorado and SPGM94021, respectively. Stable integration of the transgenes in T0 and T1 plants was confirmed through polymerase chain reaction (PCR) and Southern blotting. The NPK1 gene expression was measured through real-time-PCR. T1 plants tested in vitro for tolerance to mannitol osmotic stress maintaining a higher growth rate and showed increased tolerance to stress conditions compared to the nontransgenic plants. The transgenic sorghum had a significantly higher kernel weight under drought stress conditions than the control plants. Accordingly, the NPK1 gene might induce a mechanism that protects sorghum plants against possible water-deficiency stress conditions.

“…An important way to create new cultivars is classical breeding, also called traditional breeding (Acquaah, 2007). Traditional breeding involves the inbreeding of plants that are related to each other to achieve a combination of the unique characteristics of the plants used (Poehlman, 2013).…”
