Conteúdo: | The recipient variety 'Chinese Spring', chromosome substitution lines 1B of Timstein' and 4A of 'Thatcher', and donor varieties Timstein and Thatcher were studied with respect to six quantitative characters, viz. earliness, plant height, tiller number per plant, kernel number per spike, 1000-kernel weight and total grain yield per plant. Heterosis was observed for all characters; however, the degree and direction of heterosis varied for different characters and for different hybrid populations. Evidence for significant improvement in kernel weight and total grain yield per plant combined with early heading and short plant height were obtained. Evidence was obtained indicating that substitution lines may be effective breeding materials in common wheat (Triticum aestivum L.) breeding programs.
