Abstract The wheat gene pool has a tremendous amount of genetic diversity for salinity tolerance. During the last few decades, several wheat genetic stocks have been developed showing all three types of tolerance mechanisms, i.e., tissue tolerance, osmotic tolerance and ion (Na+) exclusion. However, delivery of improved crop varieties adapted to saline conditions has been lagging behind due to several reasons including the huge knowledge gap in understanding genetic basis of salinity tolerance i...

Les secteurs publics et prives sont de plus en plus preoccupes par les enjeux de la securite alimentaire, et y engagent une part importante de leurs ressources. Si les nouvelles technologies agricoles a l’œuvre dans le secteur permettent de realiser de nombreux progres, les politiques publiques doivent toutefois faire face aux defis subsistants. Il s’agit notamment de soutenir les agriculteurs les plus prometteurs et les plus engages dans l’agriculture moderne, tout en creant des opportunites al...

Background: Wheat genetic resources have been used for genetic improvement since 1876, when Stephen Wilson (Transactions and Proceedings of the Botanical Society of Edinburgh 12: 286) consciously made the first wide hybrid involving wheat and rye in Scotland. Wide crossing continued with sporadic attempts in the first half of 19th century and became a sophisticated scientific discipline during the last few decades with considerable impact in farmers' fields. However, a large diversity of untappe...

Synthetic hexaploid wheat (SHW) is known to be an excellent vehicle for transferring large genetic variations especially the many useful traits present in the D genome of Aegilops tauschii Coss. (2n = 2x = 14, DD) for improvement of cultivated wheat (Triticum aestivum L., 2n = 6x = 42, AABBDD). The objectives of the present study were to (1) evaluate genetic diversity among 32 selected SHW accessions with resistance to several fungal diseases using Amplified Fragment Length Polymorphism (AFLP) a...

The International Winter Wheat Improvement Program (IWWIP)—a collaboration between the government of Turkey, the International Maize and Wheat Improvement Center (CIMMYT), and the International Center for Agricultural Research in the Dry Areas (ICARDA)—develops and globally distributes improved winter wheat (Triticum aestivum L.) germplasm. The Winter Wheat Eastern European Regional Yield Trial was conducted by IWWIP during 1998–2005 using elite lines and varieties from IWWIP, Eastern Europe (EE...

Improved winter wheat (Triticum aestivum L.) cultivars for semi-arid environments in Central and West Asia are needed to increase wheat productivity. This study was conducted to determine the performance of winter wheat genotypes for semi-arid environments, analyze their stability, and identify superior genotypes that could be valuable for winter wheat improvement or varietal release. One hundred thirty three advanced breeding lines and four check cultivars were tested over a 6-year period (2005...

In 1966,the first CIMMYT released wheat variety Penjamo 62 was introduced into Sichuan;in 1989,the agreement of China-CIMMYT wheat shuttle breeding collaborative project was signed in Beijing and Sichuan was designated one of the three spring wheat shuttle sites in China.Since then,wheat breeders in Sichuan started to use CIMMYT germplasm and breeding technologies regularly for improving wheat breeding in Sichuan.In this long period of cooperation with CIMMYT,we realized that the very important ...

Summary The number of genes controlling slow rusting resistance to leaf rust (Puccinia triticina) was estimated in five spring wheat (Triticum aestivum) cultivars using quantitative formulae. Parents and F6 families were evaluated in replicated field trials under epidemics initiated by artificial inoculation. The F6 families resulted from a diallel cross involving the fast-rusting cultivar Yecora 70 and five slow-rusting wheat cultivars: Sonoita 81, Tanager ‘S’, Galvez 87, Ures 81, and Moncho ‘S...

A good understanding of how the target environments for a breeding program differentiate the germplasm with respect to yield is crucial and allows plant breeders to better target their germplasm. To determine the relationships among high rainfall yield testing locations, yield data from 8 yr of CIMMYT's High Rainfall Wheat Yield Trial (HRWYT) were analyzed by shifted multiplicative model (SHMM) and incremental sum of squares (ISS) classification analyses to group sites within and across years. I...
