Book excerpt: The Hagberg falling number (FN) is an important quality trait in common wheat being used in grain trading business and in end-use quality due to starch damage. Measuring FN can is conducted using flour sample after grain is harvested. Therefore, assessment of FN is very expensive and affected by environments where the grains were produced. Pre-harvest sprouting (PHS) and late maturity Îł-Amylase (LMA) are the two main sources that cause wheat grain samples with low FN. QTL and tightly linked molecular markers for FN, PHS, and LMA is the best alternative that can be used in early generation selection and improvement of selection efficiency. The present study conducted a comparative QTL mapping for the three related traits in a doubled haploid population derived from two hard white spring wheat cultivars UI Platinum (UIP) and SY Capstone (SYC). FN data from nine trials, PHS data from eight datasets in two experiments, and LMA data from two treatment trials were used in QTL analysis. A total of sixteen QTL for FN were detected on seven chromosome regions and five of them (QFN.UIA-1B-1, QFN.UIA-2B, QFN.UIA-3B-1, QFN.UIA-5A-1, QFN.UIA-7A-1) were detected in three or more data sets, explaining 10 to 34% of phenotypic variation. Nine QTL for PHS were identified in three or more data sets on six chromosome regions, explaining 10 to 25% of phenotypic variation. QTL for LMA were identified on chromosomes 4A (UIP HFN), 5A (UIP HFN), and 7A-1 (SYC HFN). QTL on 5A was associated with all three traits and UIP contributed to higher FN, resistance to PHS and LMA. QTL on 7A-1 was associated with FN and LMA and UIP contributed to lower FN and higher PHS score. QTL on 1B-1 was associated with FN and PHS and UIP contributed to the lower FN and higher PHS score. This study suggests that the three traits may share a little genetic information in common, therefore, selecting one trait may be able to indirectly select other related traits. This study also suggests that resistant lines to FN, PHS, and LMA can be selected through genetic recombination for QTL from the two parents. Compared to the physical map of Chinese Spring, the 5A QTL is the flanking region of Amy 3 gene. This suggests that it is necessary to study the Amy 3 gene in order to understand the genetic control of the three traits assessed in the present study.

Book excerpt: A major constraint on the production of high-quality grain around the world, pre-harvest sprouting in cereal crops causes substantial economic losses to producers and disrupts the processing, distribution, marketing, and storage of grain products. The solution to this problem must include a better understanding of the phenomenon, the development of

Available in PDF, EPUB and Kindle. Book excerpt: The 12th International Conference on Plant Growth Substances was held from 26th to 31st August 1985 in Heidelberg, F. R. G. , under the auspices of the IPGSA (International Plant Growth Sub stances Association) and the University of Heidelberg in its 599th year. As many as 750 participants from 40 countries all over the world attended the conference, including guests and staff members of the local organizers. Fine days provided an excellent background for a fruitful and pleasant meeting and all the activities accompanying the scientific programme. During the conference all current aspects concerning growth substances were treated. Altogether the par ticipants presented 207 oral reports organized in four parallel sessions and about 300 posters, for which 2 hours' poster sessions were reserved each day. The conference gained in perspective from the arrangement of five workshops in which special aspects and the most recent results could be presented by specialists in the particular fields. The topics of the workshop were: actual methods of hormone detection (orga nizer H. Kende), auxin transport (organizer R. Hertel), growth sub stances and tumour formation (organizer J. Schroder), evolution of the hormone system (organizer W. Jacobs) and problems of ap plication (organizer J. Jung). The abstracts of all presentations were collected in a Book of Abstracts available during the conference, giving a rough surveY of the whole field of plant growth substances in its present state.
