【 摘 要 】

The efficiency of selection for early matuyring, short culm and long panicle in a pearl millet population ICMV89074 was evaluated. It was possible to evaluate the efficiency of selection in a year because the materials selected in Japan were evaluated in Indonesia. Heritability values estimated by the genetic gain were 0.36 for heading/maturing date, 0.59 for culm length and 0.41 for panicle length. Thus, the selection was effective for all traits. The genetic and phenotypic correlations for panicle length vs. heading/maturing data were -0.38 and -0.97, respectively, and those for panicle length vs. culm length, they were 0.24 and 0.73, respectively. In this population, a long panicle plant tended to be early heading/maturing and a short panicle plant tended to be a short culm.
