Abstract

Most literature suggests that two-phase digestion is more efficient than single-phase. The series of two-phase digestion studies have been conducted from 2011 to 2013 at the research farm of PT Bumimas Ekapersada, West Java, Indonesia. This paper reports on a research on optimation of concentration and augmentation of EM-4 (effective microorganism-4), a local commercial decomposer, as efforts to stabilize a biogas technology which made from husk capsules of Jatropha curcas Linn (DH-JcL). The studies of increasing organic loading rate (OLR) for the two-phase digestion was conducted to improve efficiency.  The concentration variable studied was 1: 8 (1 part DH-JCL and 8 parts water), compared to 1: 12 as a control. The augmentation treatment is the addition of EM-4 by 5% (v/v). It was also examined the augmentation of F2-EM4 (150 times duplication of EM-4) due to cost consideration. The studies were conducted in the laboratory which using a liter and two liters of glass digester and glass wool as immobilized growth. The results of this study support the previous studies: the optimum concentration was 1: 8, EM-4 was able to increase biogas production in two-phase digestion, yet biogas production decrease at single-phase. F2-EM4’s ability to support production of biogas were equivalent to that of EM-4.

Abstract

Hybrid maize breeding relies on the availability of good performing inbred lines with superior combining ability. The objectives of this study were to: (1) estimate genetic paramters and heritability for agronomic and yield traits, (2) estimate correlations among traits, and (3) estimate selection-balanced inbreeding depression level from S1 to S2 generations. The S1 trial was planted from June to September 2014 at two locations, followed by the S2 trial from January to May 2015 at the same locations. Each trials was arranged in an augmented design with three blocks consisting of 72 unreplicated test genotypes, 3 unreplicated inbred lines, and 5 replicated commercial hybrid varieties as checks. The results showed that the heritability estimates were medium to high for most observed traits. Best yielding genotypes in S1 and S2 generations were derived from P27xNK6326, Pertiwi3xP31, NK6326xP31, P31xNK6326, and P31xNK33 populations. Grain yield was positively correlated with plant height, ear height, ear length, and ear diameter in S1 and S2 generations. The S2 generation exhibited inbreeding depression for grain yield. The estimates of heritability, correlations, and inbreeding depression obtained from this study could be useful for selection in corn breeding programs.Keywords: correlation, heritability, inbreeding depression

Abstract

Improvement of rice panicle architecture is one important objective in the development of improved new-plant-type rice varieties. Panicle architecture is directly related to yield components in rice. The aims of this study were to obtain information on inheritance pattern of panicle architecture on F2 generation and to obtain the best selected individuals. The experiment was conducted at Sawah Baru Experimental Farm Bogor, from May to October 2016. Two F2 populations derived from crosses of IPB 3S/IPB160-F-36, IPB160-F-36/IPB 5R and three genotypes of parents were used as experimental materials. A total of 208 and 204 plant samples were taken representing each of the two F2 populations and 20 plants representing the parents. Three panicles were taken randomly from each individual as observed samples. The results showed that additive gene action influenced number of primary branches in population of IPB 3S/IPB160-F-36, whereas in the population of IPB160-F-36/IPB 5R, most of the panicle architecture traits were controlled by additive gene action except for the length of primary branches. All of panicle architecture traits were controlled by relatively many genes except length of primary branches and number of grains on primary branches in the IPB 3S/IPB160-F-36 population. The panicle architecture of the two observed population was genetically varies. The heritability estimates were moderate to high. Selection could increase the mean of panicle architecture traits using either single or multiple traits simultaneously.Keywords: gene action, heritability, genetic variability, panicle traits

Abstract

Development of doubled haploid lines of upland rice through anther culture is one way to obtain superior upland rice varieties tolerant to drought. The objectives of this research were to determine the response of doubled haploid lines to drought stress at seedling stage and to select tolerant doubled haploid lines. The research was conducted at a screenhouse of Muara Research Station, Indonesia Center of Rice Research (ICRR) from November to December 2017. Fourteen doubled haploid lines and 4 check varieties, namely Inpago 10 and Limboto, Salumpikit (drought tolerant check) and IR 20 (drought sensitive check) were used in this study. The experiment was arranged in a randomized complete block design with three replications. The observations were conducted on leaf rolling, leaf drought, and recovery ability. Based on Friedman nonparametric analysis, HR-5-7-1-1 and HR-7-15-2-1 had moderate response with estimated median values for leaf rolling of 3.44 and 3.00, respectively. Three doubled haploid lines namely HR-2-27-2-7, HR-2-34-1-3 and HR-7-15-2-1 had moderate response to drought with estimated median value of leaf drought of 3.56. Nine lines of doubled haploid had tolerant response with estimated median value of recovery ability of 1.00-1.56. Based on weighted selection index, nine doubled haploid lines with positive and high selection index were identified; however, only two lines (HR-7-15-2-1 and B3-2) had selection index higher than Inpago 10 and Limboto.Keywords: drought tolerance, leaf rolling, recovery, weighted selection index

Abstract

Breeding rice for heavy panicle is prospective to improve production. However, the information on genotype x environment interaction (GxE) of rice panicle morphology is limited. This study was aimed to evaluate the GxE interaction on panicle morphology of heavy panicle rice (Oryza sativa L.) genotypes. The experiments were conducted in four environmental conditions. The research was conducted from December 2017 to May 2019 at the Department of Agronomy and Horticulture, IPB University, using 24 genotypes (F5-F6 generation) with 6 check varieties. The experimental design was an augmented design (3 replicates of check). Analysis of variance showed that GxE interaction effects were significant on the panicle length, number of axis nodes, primary branches number, secondary branches number, tertiary branches number, number of grains per panicle, and grain density per primary branch. The results showed that the two environments in the rainy season produced higher primary branches number, secondary branches number, tertiary branches number, number of grain per panicle, and grain density per primary branch than the two environments in the dry season. Correlation and path analyses showed that panicle length, number of secondary branches, and grain density per primary branch had a significant and direct positive effect on the number of grains per panicle. Keywords: primary branches, panicle length, secondary branches, tertiary branches

Abstract

Pemanasan global menyebabkan dampak negatif, antara lain menurunkan produktivitas padi.Pemuliaan tanaman diharapkan mampu menghasilkan varietas baru tanaman padi yang toleran terhadap cekaman suhu tinggi. Tujuan Penelitian untuk mendapatkan informasi tentang keragaan karakter pertumbuhan genotipe F2 padi dan seluruh tetuanya pada kondisi cekaman suhu tinggi. Penelitian dilaksanakan dari bulan Februari sampai Juni 2015. Materi genetik yang digunakan adalah 150 individu segregan F2 yang berasal dari persilangan IPB 4S dan IR64, 20 individu tetua IPB 4S, 20 individu tetua IR64. Semua materi genetik ditanam dalam kondisi tercekam suhu tinggi di rumah kaca Institut Pertanian Bogor. Hasil perhitungan nilai tengah menunjukan beberapa karakter memiliki nilai tengah lebih baik dibandingkan tetua dan terdapat segregan transgresif. Karakter agronomi yang diamati dikendalikan oleh gen aditif, dominan, epistasis duplikat, dan epistasis komplementer. Berdasarkan nilai heritabilitas yang tinggi dan koefisien keragaman genetik yang luas maka karakter panjang malai, persentase gabah bernas per malai, dan bobot gabah per malai contoh dapat dijadikan kriteria seleksi untuk seleksi generasi awal pemuliaan padi toleran cekaman suhu tinggi. Seleksi langsung berdasarkan jumlah gabah bernas per malai dengan intensitas 50% menghasilkan diferensial seleksi 24,7% pada karakter jumlah gabah bernas per malai.
