Kervella et al (1991) made a bibliographic review of the experiments, covering papers published up to 1989. The feasibility of recurrent selection and the interest of applying it to pure line value breeding was demonstrated. Yet a number of different points still had to be optimized: intercrossing, early generation selection and multitrait selection. A complementary review which takes into account papers from 1990 to 1992 is presented here. Some older papers which did not appear in the first review are also analyzed. An evolution in the approaches, the methodologies and concerns of the authors is emphasized. Scheme efficiency is assessed; problems which remain to be solved and the limits of the experiments are discussed. recurrent selection / autogamous species / genetic gain / pure line value

Provided they reliably predict row plot performance, hill plots should be useful for doubled haploid recurrent selection in malting barley (Hordeum vulgare L.). The primary objective of this research was to compare hill and row plot expression of agronomic and malting quality traits in an array of elite spring habit barley germplasm grown under irrigated conditions. A supporting objective was to identify an appropriate seeding rate for hill plot evaluation. Eight-replicate hill plots at four seeding rates (10, 20, 30, and 40 seeds per hill) were compared with adjacent four-replicate row plots in each of three environments. Genotype and genotype × environment interactions were significant for most agronomic traits in both plot types. Significant, linear genotype responses to hill plot seeding rates were observed for most agronomic traits. Seeding rate had no consistent effect on the expression of malting quality. The percentage of lines in common in the two plot types at 25 and 50% selection intensities was the most useful comparison statistic and indicated hill plot selection should be effective for most agronomic and malting quality traits. Although yield heritability estimates were consistently high in both hill and row plots, there was little relationship between trait expression in the two plot types. Differential tillering in response to hill plot competition is likely responsible. A seeding rate of 10 seeds per hill should be appropriate in preliminary screening for traits amenable to hill plot selection in irrigated spring habit malting barley.Key words: Hordeum vulgare L., malting quality, breeding methods, barley
