As know, International Winter Wheat Improvement Program (IWWIP) develops Winter Facultative Wheat (WFW) germplasm and distributes nurseries, called International Nurseries (IN) to IWWIP cooperators annually. This time of the year is the busiest time for IWWIP parties, Turkey, CIMMYT and ICARDA that they together carry out the IWWIP breeding program. We fill thousands and thousands of envelopes to prepare the IN`s. 24IWWYT-IRR and 23IWWYT-SA yield trials and, 29FAWWON-IRR and 29FAWWON-SA observation nurseries are the nurseries will be distributed to more than 80 IWWIP cooperators in more than 40 countries for planting in 2021-2022 growing season.
A Brief Report of the IWWIP Annual Activities in 2019-20 Season: from national/international cooperation to registered varieties
In 2020, wheat grain yield was generally lower than the average of many years. The total precipitation was irregular and less than long term average in 2019-20 growing season in all locations where IWWIP nurseries have been planted. Planting was done timely in all locations however, since there was less rain after sowing, germination was late and negatively affected. The stripe rust epidemic (artificial) in both Haymana and Izmir locations and high severity of leaf rust epidemic (natural) in Adapazarı allowed screening of the IWWIP germplasm. In addition, advanced IWWIP germplasms were evaluated under the natural stem rust epidemic in Eskisehir location.
First cycle of 22,000 plants from 100 cross planted as F3 generation in the speed breeding greenhouse in last October-December were harvested.
Advanced IWWIP germplasms and introduction materials are distributed every year through International Nurseries for observing their performance in different regions and providing germplasm to breeding communities. The reports for the nurseries (27th FAWWON-IRR, 27th FAWWON-SA, 23rd IWWYT-IRR and 22nd IWWYT-SA) distributed for 2019-2020 season are currently available at Nursery Data section of web site. We would like to grateful to IWWIP cooperators to help generating the data and sharing their insights with us.
Dr. Sanjaya Rajaram passed away.
Dr. Sanjaya Rajaram (Raj with his widely known name) was born in India in 1943. After completion his Phd in plant breeding from the University of Sydney in Australia, he started as a wheat breeder at the International Maize and Wheat Improvement Center (CIMMYT) with Norman Borlaug in 1969.
The history, activities, impact and future of the IWWIP have been evaluated by Morgounov et al., (2019) and published at Frontiers of Agricultural Science and Engineering. IWWIP cooperation with researchers in Turkey, Central and West Asia and several US universities has resulted in a number of publications reviewed in this paper. The role of winter wheat in the global context and production environments, current IWWIP breeding system, research highlights, impact, and future perspectives were examined by authors.
