Abstract

The purpose of this research was to obtain lines of candidates restorer that has a good combining ability against three plants Cytoplasmic Male Sterile (CMS/A). The research was conducted at the research field at PT. Syngenta Indonesia Cikampek West Java, Jati Sari, Balonggandu village. Crossed design and  analysis arranged by following  line x tester desing. Ten hybrid line restorer fertility and three line CMS planted the field using randomized complete block design with  2 replications, treatment consisting of 43 treatment so getting 86 unit experiment with the analysis resources combining ability. This research was the observed against character of high of plants, number of filled grain per clump , number of filled per clump, number of unfilled per clump, weights 1000 grains, number of productive, panicle length, persentase fertiliy panicle. The result showed that all the characters observed having had significant variance of general combining ability (GCA) and specific combining ability (SCA). Expression of the characters above controlled by the action of genes additive or non-aditif.

Abstract

This study aims to determine the effect of Urea fertilizer on the growth and production of local rice germplasm from Aceh. The results showed that treatment of Urea very significant effect on the number of tillers at the age of 60 days after planting, and significantly affected the number of seedlings 45 days after planting. Growth and yield the best found in the treatment of urea 0.65 g pot-1 (200 kg ha-1). Varieties very significant effect on plant height age of 30, 45 and 60 days after planting, tillering, number of tillers at the age of 45 and 60 days after planting, life begins to flower, the percentage of grain contains, the percentage of empty grains, 1,000 grain weight, yield per plot and yield per hectare. Continously varieties significantly affected the number of seedlings 15 days after planting. Productivity of rice plants is best found in the varieties Sipirok 9.58 tons ha-1. There is no real interaction between the urea treatment of all varieties of variable growth and yield of rice plants.
