Over the past 50 years, thousands of rice varieties have been introduced by plant breeders to agricultural communities all over the world. Despite the improvement of attributes such as grain yield and tolerance to biotic and abiotic stresses, a significant portion of farmers still prefer local varieties over the improved cultivars. The main reasons for this perference are the absence of a dire...
massive amounts of information for plant breeding (Stuber et al., 1999; Miflin, 2000), an option of improving Crop modelers and geneticists have developed a vision of their roles breeding efficiency is to develop and utilize a thorough in plant breeding from their own perspective. However, to improve breeding efficiency, interdisciplinary collaboration becomes increasunderstanding of morphophys...
Advances in automation and data science have led agriculturists to seek real-time, high-quality, high-volume crop data to accelerate crop improvement through breeding and to optimize agronomic practices. Breeders have recently gained massive data-collection capability in genome sequencing of plants. Faster phenotypic trait data collection and analysis relative to genetic data leads to faster an...
Until 1994, only scarce research existed on these plants; however the worldwide interest in this novel fruit crop is evident, as numbers of pitaya-related publications have grown rapidly, especially during the past decade .There is a big confusion about both botanical and commercial names and there is a need to clear this point. herein, we attempt to review existing knowledge on the taxonomy, b...
Accelerated breeding of plant species has the potential to help challenge environmental and biochemical cues to support global crop security. We demonstrate the over-expression of ArabidopsisFLOWERING LOCUS T in Agrobacterium-mediated transformed cassava (Manihot esculenta Crantz; cultivar 60444) to trigger early flowering in glasshouse-grown plants. An event seldom seen in a glasshouse environ...
The world population is estimated to be 9.2 billion in 2050. To sufficiently feed these people, the total food production will have to increase 60% 70%. Climate models predict that warmer temperatures and increases in the frequency and duration of drought during the present century will have negative impact on agricultural productivity. These new global challenges require a more complex integra...
The genetic dissection of complex traits plays a crucial role in crop breeding. However, genetic analysis and crop breeding have heretofore been performed separately. In this study, we designed a new approach that integrates epistatic association analysis in crop cultivars with breeding by design. First, we proposed an epistatic association mapping (EAM) approach in homozygous crop cultivars. T...
In the crop breeding process, the use of data collection methods that allow reliable assessment of crop adaptation traits, faster and cheaper than those currently in use, can significantly improve resource use efficiency by reducing selection cost and can contribute to increased genetic gain through improved selection efficiency. Current methods to estimate crop growth (ground canopy cover) and...
A. Pratap and J. Kumar (eds.), Alien Gene Transfer in Crop Plants, Volume 1: Innovations, Methods and Risk Assessment, DOI 10.1007/978-1-4614-8585-8_2, © Springer Science+Business Media New York 2014 Abstract Wide or distant hybridization has been widely used as an important tool of chromosome manipulation for crop improvement. The chromosome behaviors in F 1 hybrids provide us with the essenti...
