| dc.description.abstract | Wheat germ agglutin (WGA) present in the embryo of a bread wheat grain is a mixture of three isolectins, viz CLA, CLB and CLo which are coded by genes located on the chromosomes 1A, IB and ID. Their respective absolute amounts were determined in 62 Nigerian and five Chad landraces. Added was the Madagascar variety Kanem which is stated to be selected from Chad material. Some of the Nigerian landraces were formerly identified as derived from Indian/Pakistani wheat varieties/landraces introduced into Northern Nigeria before 1940. These had relatively high CLD/CLA and CLB/CLA ratios. Other Nigerian landraces with such high ratios were postulated to come from India/Pakistan, too. The Chad wheats, except Kanem, have WGA amounts and ratios similar to those native to Northern Nigeria. This may point to a common history. Kanem is said to be bred in Madagascar from Chad wheats. Apparently it has a different origin. So the determination of the WGA amount and its isolectin composition is a helpful means to identify the history of a landrace or of an improved variety. | en_US |
