Cereal breeding and its future trends.
This paper seeks to show that cereal breeders have been successful when their objectives have been clear. It is suggested that the end of cereal improvement is not in sight and that breeders will continue to make significant advances in many directions. In order to look at future trends it is necessary to examine what has been achieved and to consider the principles on which cereal breeding is ...
متن کاملTowards molecular breeding of reproductive traits in cereal crops.
The transition from vegetative to reproductive phase, flowering per se, floral organ development, panicle structure and morphology, meiosis, pollination and fertilization, cytoplasmic male sterility (CMS) and fertility restoration, and grain development are the main reproductive traits. Unlocking their genetic insights will enable plant breeders to manipulate these traits in cereal germplasm en...
متن کاملRecent advances in molecular tool development for drought tolerance breeding in cereal crops: a review
Drought stress is one of the major yield constraints for cereal crops. Traditionally, for developing drought tolerant cultivars, selection either direct or indirect is practiced. Although this approach is effective, yet time consuming and labour intensive. Identification of drought related quantitative trait loci (QTLs) coupled with marker assisted selection has shown some positive results. Tra...
متن کاملTriticeae Resources in Ensembl Plants
Recent developments in DNA sequencing have enabled the large and complex genomes of many crop species to be determined for the first time, even those previously intractable due to their polyploid nature. Indeed, over the course of the last 2 years, the genome sequences of several commercially important cereals, notably barley and bread wheat, have become available, as well as those of related w...
متن کاملBreeding for salt tolerance in cereal and legumes: Status and prospects
Introduction Soil salinity is an important limiting factor for crop yield improvement, which affects 5-10% of arable lands approximately 75-100 million ha worldwide, depending on estimates (Szabolcs, 1994; Munns, 2002). Most crops are sensitive to salt stress at all stages of plant development, from seed germination through vegetative and reproductive growth. Salt originates from marine geologi...
