Abstract

Penelitian ini bertujuan untuk menguji pengaruh penambahan DEAE-selulosa terhadap kualitas agarosa dari bahan baku Rhodymenia ciliata. Penelitian terdiri dari dua tahap yaitu penelitian pendahuluan yang bertujuan untuk menentukan konsentrasi NaOH optimum pada pra-ekstraksi agar dan penelitian utama yang bertujuan untuk menguji pengaruh perbandingan DEAE-selulosa dengan rumput laut Rhodymenia ciliata terhadap kualitas agarosa. Hasil penelitian menunjukkan bahwa pada perlakuan pemberian DEAE-selulosa 27% terhadap berat rumput laut kering menghasilkan agarosa optimum dengan sifat-sifat fisik yang terbaik.Kata Kunci : Agarosa, DEAE-selulosa

Abstract

Rice is one of the commodity that is very important as a staple food for more than 95% of the population in Indonesia. Rice production should be increase continously in line with the increasing population of Indonesia. Therefore, it is important to improve the quality and quantity of the production of rice. Improvement in terms of quality through development of rice with high protein content, beside of its production. Protein content in rice grain be important because it serves as an essential nutrient that can be used in the growth and cell recovery. This research be conducted in the village Sokawera, district Baturaden, Banyumas Regency. The material used is a population of F3 results of crossing with G39 x Milky Rice and G39 x Ciherang. The results showed the highest protein content in population of crossing G39 x Milky Rice is amount 13.42%. and a crossing G39 x Ciherang is amount 13.05%. The value of the correlation of protein content with component output is -0.36. There is no relations between production rice and its protein content.

Abstract

One of the goals of Indonesia's rice improvement program is to develop high-yielding varieties with long and slender rice grains. This study aimed to estimate the genetic parameters affecting gene action, amount of gene action, number of gene control, magnitude of genetic variability, heritability, genetic advance, and correlations between yield components and yield of Inpari 31 x Basmati Delta 9 in the F2 generation. The experiment was carried out at an experimental farm at the Faculty of Agriculture, Jenderal Soedirman University, Purwokerto, Central Java, Indonesia. The genetic material used was seed from an F2 population crossed between Inpari 31 and Basmati Delta 9 with the two parental genotypes. Estimates of skewness, kurtosis, genetic variability, heritability, genetic advance, correlations between traits and path analysis were calculated for yield and yield component traits. Results show that additive and complementary epistatic action control yield-related and yield traits. Yield-related trait components and yield are controlled by a monogenic or polygenic genes, depending on the observed trait. Wide genetic variability, high broad sense heritability and high genetic advance were found in the number of productive tillers per hill and grain weight per panicle.  These traits show a significant positive correlation and have a direct effect on the yield; therefore, they can be used as traits in the selection to produce high-yielding rice, with long rice sizes and slender shapes.   Keywords: F2 population; genetic parameters; interrelationship among traits; rice

Abstract

Rice length and shape are the important quality traits in rice that affect consumer acceptance and price. Rice length and shape can be improved through crosses followed by selection. Genetic parameters influence effective selection. The research objectives are to estimate genetic parameters for rice length and shape in the F2 population of Basmati Delta 9 x Koshihikari and Basmati Pakistan x Inpago Unsoed 1. F2 rice population from crosses of Basmati Delta 9 (extra-long, slender) x Koshihikari (short, round), Basmati Pakistan (extra-long, slender) x Inpago Unsoed 1 (medium, medium), and the parents are used for research material. The genotype is planted using an experimental design with no replication. Rice length and shape data were collected from each plant. The collected data is used to estimate the genetic parameters of rice length and shape. The results show that polygenes control rice length and shape. Transgressive segregation is obtained in the F2 population of Pakistan Basmati x Inpago Unsoed 1. The genetic diversity of rice length and shape is low, so reducing the selection intensity of these traits is suggested. The estimate of broad sense heritability and genetic gain of rice length and shape was high.

Abstract

Current research was conducted with the objectives to identify the utmost traits that may be beneficial for the higher productivity of the grains on high protein content genotypes lines by path coefficient. Path coefficient can define coefficient correlation directly and indirectly to gain information about nature relationship between yield component and protein content to grain yield. Research material consisted of 61 selected plants from G39×Ciherang and 66 selected plants from Mentik Wangi×G39 at F4 generation. Plants were planted in Banyumas in May 2011. Number of panicles per plant, panicle length, 1000 g of grain weight, percentage of filled grain per panicle, protein content, and grain yield were correlated by using Pearson correlation and were followed by path coefficient. Number of panicles per plant, panicle length, 1000 g of grain weight, percentage filled grain per panicle, and protein content were used as dependent variable, while grain yield was used as independent variable. The result showed that protein content in both populations was not correlated with all yield components. The numbers of panicles, followed by panicle length, had highest positive direct effect to yield. The number of panicle was a positive mediator variable to yield from another variable.Keywords: correlation, direct effect, indirect effect, mediator variable, path analysis
