Wheat: Production of Haploids, Performance of Doubled Haploids, and Yield Trials

Abstract

Wheat is the most important worldwide cereal, yet very few countries have important research programmes on the in vitro androgenesis and its use in wheat breeding. Only in China this problem has been studied from a theoretical as well as practical point of view (see Section I.3, this Vol.). In France, the studies are concerned with the use of doubled haploids (DH) in breeding programmes to create new varieties or to compare breeding methods. The first results on wheat anther culture (Triticum aestivum L. 2 n = 6 × = 42) were published in 1973 by the Chinese (Chu et al. 1973, J. Ouyang et al. 1973, C. C. Wang et al. 1973) and French (Picard and De Buyser 1973) workers. Since then many studies have been undertaken (see Sections I.1, I.2, I.3, this Vol.).
