Abstract

The success of selection in plant breeding program is determined by genetic variabiliities, heritability values and the correlation between agronomic characters and yield. The study aims to determine the genetic variability, heritability and the effec of agronomic characters to grain yield. The experiment was conducted in February to May 2016 in Grobogan, Central Java. The experiment consists of twelve genotypes of maize hybrids, arranged in a randomized block design with three replications. The characters observed were plant height, ear height, number of harvested ear, shelling percentage, moisture content of grain harvested, weight of 100 grains, ear length, ear diameter, number of rows per ear, number of seeds per row per ear, and grain yields. The results showed that the genetic variability of agronomic characters was broad, except ear diameter. Almost all of the heritability values of yield components were high, except harvested ear weight and ear diameter. The characters of plant height, ear height and as the genotypic gave high of a direct effect on the yield higher, while direct effect of the phenotypic character of ear hairves on grain yield are higher.

Abstract

High salinity is one of the major abiotic stresses affecting rice production. Previously, we have identified transposonDs insertional mutant rice lines cv Nipponbare showing improved tolerant under salinity stress The objective of thisresearch was to determine the Ds insertion site in chromosomal DNA from one of the salt tolerant mutant line (170-10) and identify the genes in the proximity. A specific amplicon around 450bp from the mutant rice line 170-10 wassuccessfully isolated with TAIL PCR technique using the degenerate and a specific Ds primers. Bioinformatics analysesfound that the insertion was located in a putative CDS designated as Os11g0686500 in chromosome 11 at the 2nd exon.Two putative CDS’s within the proximity of the Ds insertion site downstream and upstream the insertion sites were alsoidentified.

Abstract

So far, regression analysis is used to model the mean of response variable as a function of some independent variables, using the least squares (LS) method. In general, the LS method is able to describe well the measure of central tendency, however it is not robust against outliers. Therefore, in certain cases, a regression analysis that minimizes the sum of absolute residuals (least absolute deviation - LAD) is required, which is more robust against outliers. So far, the value of the regression coefficient is not modeled and only depends entirely on the data processed. In some cases, the sign and the value of regression coefficients need to be controlled, in order to be in the meaningful range. The results of this study showed that the modification of the constraints on the LAD regression able to control the regression coefficients to be in the meaningful range. The results of bootstrap showed that distribution of controlled regression coefficients were different from distribution of uncontrolled regression coefficients.

Abstract

Produktivitas jagung ditentukan oleh kualitas lingkungan tumbuh dan varietas yang ditanam. Informasi variasi genetik tanaman jagung perlu diketahui sebagai dasar pertimbangan dalam penyusunan strategi konservasi, pemuliaan, pengelolaan, dan pemanfaatan sumber daya genetik tanaman. Syarat utama yang diperlukan oleh pemulia untuk merakit varietas unggul baru adalah tersedianya materi genetik dengan keragaman yang luas. Tujuan penelitian ini adalah untuk mengelompokkan plasma nutfah jagung lokal berdasarkan karakter kuantitatif tanaman. Penelitian dilaksanakan di Kebun Percobaan Cikemeuh, BB Biogen, Bogor, menggunakan 44 aksesi jagung lokal asal NTT dan enam aksesi jagung lokal asal Jawa Timur. Percobaan menggunakan rancangan acak kelompok dengan tiga ulangan, sebagai perlakuan adalah 50 aksesi jagung. Karakter yang diamati meliputi sifat agronomis dan morfologis tanaman. Hasil penelitian menunjukkan terdapat 5 kelompok aksesi, dan jagung aksesi Mendi berumur genjah, dapat dipanen pada umur 74 hari. Sumber daya genetik jagung dengan karakter biomas (bobot brangkasan) tertinggi dimiliki oleh aksesi Pena Tasa. Bobot 100 butir tertinggi dihasilkan oleh aksesi Pena Oban. Aksesi-aksesi tersebut dapat digunakan sebagai bahan pemuliaan tanaman jagung untuk menghasilkan varietas unggul.

Abstract

Selection to identify corn genotypes that are able to use water effectively becomes a target in plant breeding activities to improve drought tolerance.  Research to determine the performance appearance of agronomic characters, morphology, and physiology of several hybrid genotypes has been carried out in the Experimental Field of Cereals Research Institute, Maros, South Sulawesi, June - October 2016 in drought stress conditions using 65 hybrid corn genotypes. The research was conducted with 65 corn hybrid genotypes arranged in a randomized completed block design with three replications.   Drought stress treatment was started before the flowering phase until the physiologically mature. The result indicated that agronomic, physiology and  yield characters that  are significant and positively correlated  with o grain yield  are plant height, ear  height, stalk diameter, leaf area, leaf chlorophyll, leaf moisture content, stomata area, wet ear weight, ear leght, number of ear harvest, number of grain/rows and weight of 1000 grain. Leave rolling score, leaf senescence and leaf temperature are physiological characters that haved  negative correlation with the grain yield, as well as agronomic characteristics of days to silking, days to anthesis and ASI value. Promising hybrid (CML 505/NEI 9008-9-5-B-B-B-B)// CY11, (CML 538/DMRYCML-2-7-B-B-B-B)//MAL03, (CML 538/DMRYCML-5-5-B-B-B-B)//MAL03, (CML 505/NEI 9008-9-4-B-B-B-B)//CY11, (CML 505/NEI 9008-18-2-B-B-B-B)//CY11, (CML 505/NEI 9008-9-1-B1-B-B-B)// CY11, (CML 538/DMRYCML-1-3-B-B-B-B)//CY11, (CML 505/NEI 9008-14-1-B-B-B-B)// B11209, (CML 505/NEI 9008-29-2-B-B-B-B)//CY11 dan (CML 505/NEI 9008-21-2-B-B-B-B)//MAL03 show better  agronomic performance, yield components andgrain yield potential than Bima 9, Bima 16, Pertiwi 3 and P31. Those promising hybrid  of drought tolerance could  be further developed.

Abstract

Climate change has an impact on decreasing agricultural production, especially food crops. The rate of decline in agricultural production due to climate change ranges from 5-20%.The objective of this study was to forecastfood-cropsat Papua Province that are tolerance and adaptable to climate change using trend method. This study used four models of trend analysis, i.e: linear least square pattern, quadratic, exponential, and moving averages, with secondary data base of rice, maize, soybean and sweet potato production; climate data (rainfall); productivity and harvested areas from 1970-2015. These data were used to estimate food crop production in the year of climate change to determine their impact on food-crop production. Results showed that soybean was the most sensitive crop to climate change. It has the biggest impact on production, yield declined on both El Nino (10.7%) and La Nina (11.4%). The lowest impact was on rice crop, which is generally cultivated on the wetlands, El Nino decreased of production of 2.9% and La Nina increased production 2.4%, respectively. Two other crops, maize production decreased 7.4% on the El Nino and 3.9% increased during the La Nina. Futhermore, the the analysis revealed that sweet potatois the most resistant crop to climate change since it production increase by 2.5% during El Nino. As conclusion, moving average trendof order 2 model was most appropriate to estimate the value of rice and soybean production in the 1970-2015 period.The quadratictrend model wasapropriate  to estimate maize and sweet potato production based on its the MAPE, MAD, and MSD values.
