Gene action and heritability of F4 generation derived from the crossing of Silopuk red rice cultivar with superior Fatmawati variety

Abstract

Population F4 is a segregated population the character of certai, so important to know the parameters of genetics. The purpose of our research to determine action of gene and the values expected heritability population F4 (Silopuk X Fatmawati). The research has been from month of October 2017 to February 2018 in land farmer Padang Limau Manis. The research use method experiment without repitition the head to row with analysis Z Skewness and Z Kurtosis. The genetic material of this research is rice seed on the F3 generation from the selection of pedigree crosses between silopuk and Fatmawati superior variety and the other seeds were Silopuk cultivar and Fatmawati superior variety as control. The research data showed that Z test skewness and Z test Kurtosis for whole characters observed were dominant controlled by minor genes. The character age of flowering, plant height, length of panicle and percentage filled grain per panicle were controlled by many gene additive. The broad heritability value for all character observed in the F4 population ranged from 0.01-0.99 with low to high criteria.
