WE DEVELOPED, TNAURICE: a database comprising of the rice varieties released from a public institution, Tamil Nadu Agricultural University (TNAU), Coimbatore, India. Backed by MS-SQL, and ASP-Net at the front end, this database provide information on both quantitative and qualitative descriptors of the rice varities inclusive of their parental details. Enabled by an user friendly search utility...

Biological control is an important ecosystem service delivered by natural enemies. Together with breeding for plant defence, it constitutes one of the most promising alternatives to pesticides for controlling herbivores in sustainable crop production. Especially induced plant defences may be promising targets in plant breeding for resistance against arthropod pests. Because they are activated u...

studies of genetic diversity of plant populations are very important tools for plant breeders. in this study, 110 rice genotypes, including 39 iranian local, 20 iranian improved and 51 foreign improved varieties were studied for 14 agronomic traits in the the rectangular lattice design at the rice research institute of iran (rasht). the analysis of variance showed that there were significant di...

Modern scientific knowledge and indigenous or traditionally based knowledge are often assumed to be fundamentally different and incomparable. Testing this assumption is important theoretically and for supporting scientist-farmer collaboration to improve farmers’ well-being in their own terms. We illustrate the use of scenarios based on a basic biological model to understand farmers’ theoretical...

Fusarium head blight, one of the most destructive diseases of wheat (Triticum aestivum L.), results in significant economic losses from reduced grain yield and quality. In recent decades, the disease has been frequently recorded, especially under warm and wet climatic conditions. Genetic resistance has engaged plant breeders because the use of resistant cultivars is the most economical, effecti...

UNLABELLED PREMISE OF THE STUDY Chloroplast microsatellite markers were developed for Festuca rubra to examine its population genetic characteristics, taxonomy, and coevolution with its endophyte Epichloë festucae. • METHODS AND RESULTS Thirteen polymorphic markers were identified from the chloroplast genome of a F. ovina accession and intergenic chloroplast sequences of F. rubra accession...

Plant breeders utilize directed selection and transgenics to produce novel cultivars of diploid and polyploid species. DNA sequence is clearly important in these processes, but growing evidence implicates epigenetics as an important factor in controlling genetic variation and gene/transgene expression. In this article, we focus on epigenetic variation defined as mitotically and meiotically heri...

The purpose of this article is to show how quantitative genetics has contributed to the huge genetic progress obtained in plant breeding in Brazil in the last forty years. The information obtained through quantitative genetics has given Brazilian breeders the possibility of responding to innumerable questions in their work in a much more informative way, such as the use or not of hybrid cultiva...

D. L. Craig CORN SILAGE BREEDING

Attaining high-quality corn silage is a critical aspect of profitability for corn and animal productivity. Biotechnology traits that reduce stress likely have more potential yield benefits for silage growers than even grain farmers. The corn genomes have been sequenced. We’ve put in thousands of markers that let us tag individual genes. Breeders have tools unlike anything they’ve had in the his...

The CEREALAB database aims to store genotypic and phenotypic data obtained by the CEREALAB project and to integrate them with already existing data sources in order to create a tool for plant breeders and geneticists. The database can help them in unravelling the genetics of economically important phenotypic traits; in identifying and choosing molecular markers associated to key traits; and in ...
