Major genes involved in chlorophyll synthesis in bread wheat (Triticum aestivum L.) cultivars

Abstract

The yield of wheat has reached to a plateau and therefore concerted efforts are being made by several wheat researchers world over to increase the yield of wheat. Studies on photosynthetic capacity (Pmax) in Triticum species have shown that wild species have higher Pmax than hexaploid wheat [1, 2, 3]. It is therefore, desirable to identify the genes responsible for high photosynthetic efficiency in wild diploid wheat species and transfer these to bread wheats for increasing their yielding ability. The present report describes the genetics and chromosome location of genes involved in chlorophyll synthesis in nine hexaploid wheats, so as to facilitate the efficient and selective gene transfer from wild species to bread wheat.
