摘要：The rice improvement program in Indonesia is addressed to develop high-yielding varieties with long slender rice grain. The purpose of this study, therefore, was to estimate the genetic parameters, i.e., gene action, number of genes control, the magnitude of genetic variability, heritability, genetic advance and interrelationship of traits of yield components and yield were studied in the F2 generation of Inpago Unsoed 1 x Basmati Delta 9. The experiment was carried out at the experimental farm of Agriculture Faculty, Jenderal Soedirman University, Purwokerto, Central Java, Indonesia, from October 2018 - February 2019. The genetic material used was seeds of F2 populations derived from the crossing between Inpago Unsoed 1 and Basmati Delta 9, and the two parental genotypes. The estimates of Skewness, Kurtosis, genetic variability, heritability, genetic advance, and interrelationship were computed for yield and yield component traits. Broad genetic variability, high/medium heritability, and high genetic advance were found in the number of productive tillers, grains per, and grain yield per plant. The number of productive tillers and grains per panicle had a high correlation coefficient and positively direct effects on the grain yield per plant. It could be concluded that the number of productive tillers and the number of grains per panicle might be considered as criteria of selection for the development of high yield and long slender rice grain through pure line selection.
