Abstract:
Seed quality testing is one of aspect control and quality assurance for certified seeds. The grain shape is one of the important parameter components tested in the seed certification process especially in the field. The common method used were using human/ analysts visual observation. It has a high degree of subjectivity and low efficiency. Observation of complex samples in the field requires an alternative observation that is more subjective and accurate. An alternative technology for identifying seeds during certification and production is identification based on digital images. The purpose of this study were to identify and classify rice seeds based on physical form using digital image analysis. A total of 20 varieties with various shapes have been taken with a microscope that connected to the camera and computer. The resulting image file was analyzed using imageJ 1.51k software and analyzed statistic to discriminate the seeds tested according to their group. Results from this study indicated that digital image analysis is able to identify and classify seeds. The grouping of seeds into long, medium and round seed categories based on perimeter, circularity, AR, and round parameters with successive correlation levels is 95.4%; 82.5%; 45.3% and 38.9%. This method is more sensitive to identifying seed characteristics than eye visualization of seeds whose physical size is outside the range of numbers specified in the description. For example Cisadane, Gilirang and Ketonggo seeds.

Abstract:
Multi-environment experiment could reveal the performance and adaptation of the advanced breeding lines for specific or general environment. The objective of the present investigation was to analyze the pattern of Genotype x Environment (G x E) interaction for grain yield of 67 genotypes by Additive Main effects and Multiplicative Interaction (AMMI) model using the data generated from observational yield trial in three different coastal rice environment in Indonesia including one site in coastal of Eretan, Indramayu (West Java) and two sites in the coastal area of Mataram, West Nusatenggara during dry season of 2009. In each location, the experiment was arranged in a randomized complete block design with three replications, 5m2 plot size and 20 cm x 20 cm of planting space. Standard management practices for irrigation field were followed for all trials. The results showed the highly significant genotypic and G x E interaction. The genotype x environment (GxE) interaction influenced the relative ranking of the genotypes across environment. Genotype 62(IR76397-2B-6-1-1-1-1), G3(IR58427-5B-15), G61(IR76393-2B-7-1-1-3-1), G19 (IR73055-8-1-1-3-1), G26 (IR 77674-3B-8-2-2-14-1-AJY5), G38(IR77674-3B-8-2-2-14-2-AJY4), G35(IR77674-3B-8-1-3-13-2-AJY2), G44(IR68144-2B-2-2-3-3), and G53(IR72593-B-18-2-2-2) produced higher yield compared to the overall mean, and showed low G x E interaction effect with low ASV (AMMI’s Stability Value) score presented the high yield genotype with high adaptability compared to the checks. G23(IR77674-B-20-1-2-1-3-6-4-AJY1,8.39 t/ha), G25 (IR 77674-3B-8-2-2-12-5-AJY2, 8.11 t/ha), G24(IR77674-3B-8-2-2-8-3-AJY4, 8.32 t/ha), G18(IR72049-B-R-22-3-1-1, 8.78 t/ha), produced high yield and indicated suitable for Eretan environment. Both the stable genotypes and the specific adaptation genotypes with the highest average yield compared to the checks will be further evaluated in prelimenary yieid trials in the several environments with the bigger size plot.

Abstract:
The research objective was to analyze the increase of rice production, income, and resource efficiency (land, labor, and capital use) of minapadi applicating “jajar legowo” plant spacing, a case in Sirnasari Village, Sariwangi Sub-District, Tasikmalaya Regency. The survey method was used in the research. 35 minapadi farmers applicating the jajar legowo plant spacing and 8 minapadi farmers implementing the tegel plant spacing were taken as samples from a population size of 78 farmers. Comparative descriptive analysis was used to determine differences in production, income and resources efficiency (the use of land, labor, and capital). Unpaired t-test was used to test differences in rice production and farmers’ income applicating the jajar legowo and tegel plant spacing. The results showed that minapadi applicating the jajar legowo plant spacing increased rice production, fish production, and farmers' income by 18.25, 32, and 40 percent respectively. The resources use of land, labor, and capital in minapadi applicating the jajar legowo plant spacing was more efficient than that of applicating the tegel plant spacing.

Abstract:
Adoption of the hybrid rice varieties by farmers is often impaired by the high price of hybrid seed, due to low yields in hybrid seed production fields. Female outcrossing ability and female hybrid seed production ability, defined as the rate of filled spikelets of the male sterile line and as its grain yield under outcrossing, respectively, determine plant traits for hybrid seed yield. We identified an morphological characters and outcrossing rate ability of 6 hybrid rice combination that affect grain yield of hybrid rice seed production. The experiment conducted in 3 locations i.e. Subang, Malang, and Ungaran districts during dry season of 2016. Subang is the best location to hybrid rice seed production with the highest average of grain yield. Hipa 19 was the hybrid varieties having > 1 ton/ha grain yield highest that others. The important agronomic characteristics that affected of F1 grain yield i.e. plant height, number productive tillers, number of filled grains, exerted panicle rate, dan outcrossing rate. Correlations between number of filled grains, outcrossing rate, and grain yield were tight and highly significant. High yield potential and cost-effective for hybrid seed production can be achieved using hybrid rice with high outcrossing rate and suitable condition of an environment.

Abstract:
East Java Province supplies one third of the national peanut production. The farmland of peanut production centers in the region is a coastal area prone to salinity. The use of variety adaptive to salinity stress is an effective strategy to cope sainity problem and to optimize the use of salt-affected land. The aim of the research was to evaluate the adaptability of peanut varieties to salinity stress.The research was conducted in the 2018 dry season in the saline paddy field in Gesikharjo Village, Palang Sub District, Tuban Regency with EC 14.54 dS/m. The treatments consisted of seven groundnut varieties (Singa, Singa, Kancil, Takar 2, Bison, Hypoma 2, Tuban, and Jerapah), using a randomized complete design, four replications. Observations consisted of growth parameters, yield and yield components, proline and macro nutrient (N, P, K) content. The results showed that high salinity stress reduced seed germination, plant growth, yield components and yields of all varieties tested. Based on the ability to survive and yield, Singa variety have showing higher tolerance to salinity stress or more adaptive than other varieties, while the lowest one was found in Jerapah variety. The salinity tolerance of Singa variety did not indicate to be associated with high proline content, but it seem more related to the ability to absorb higher N, and keep K high to reduce negative effect of Na.

Abstract:
Effect of Insecticides to Brown Planthopper (Nilaparvata lugens Stal) Adaptation on Resistant Rice Varieties. Brown planthopper (BPH) (Hemiptera: Delpachidae) is one of major pests on rice cultivation in Indonesia. Resistant rice varieties and insecticides are commonly used by farmers in BPH management. But, BPH can rapidly adapt on long-term planted varieties and insecticide. The aim of research was to study the ability of insecticide resistance BPH in adaptation on resistant rice varieties. This study was conducted at Indonesian Center for Rice Research from October 2018 to June 2019. BPH’s were collected from farmer field and reared for 6th generation. BPH’s were divided into four insecticide population. BPH population sprayed each generation by BPMC (BPMC-BPH), imidacloprid (imidacloprid-BPH), pymetrozine (pymetrozine-BPH), and unsprayed (Control-BPH). In first generation, insecticide resistance conducted to obtain baseline data of BPH resistance to imidacloprid, BPMC and pymetrozine. On 6th generation, insecticide resistance test repeated to each population. Four BPH population were tested for the survival rate, fecundity, amount of honeydew, and rice varieties reaction. Result showed that Field population 1st generation were resistance to BPMC and imidacloprid with Resistance Factor (RF) 4.1 and 13.5-fold, respectively, while to pymetrozine was indicate resistance (RF 3.7-fold). In 6th generation, LC50 all insecticide population were increased, while in Control-BPH were decreased. Inpari 13 still effective againts BPH in all test results. Insecticide resistance-BPH tend to lower adaptation on resistant variety than insecticide susceptible-BPH.

Abstract:
Brown plant hopper (BPH) is one of the main pest of rice in Indonesia and it occurred every years with fluctuate acreage. BPH is also vector of Rice Ragged Stunt Virus (RRSV) and Rice Grassy Stunt Virus (RGSV). Green Super Rice (GSR) was designed to have resistance to major pests and diseases so that it need less pesticides and thus save ro environment. GSR was developed in IRRI and China and was tested in Indonesia since 2009 until now (2019). This research was aimed to study the genetic variability and heritability of 26 selected GSR lines to RRSV and RGSV along with four check varieties. The experiment was conducted in ICRR Sukamandi and Pusakanagara Experimental Station. The experiment was arranged following randomized complete block design with three replications. Transplanting was done into 21 days old seedling into 25 cm x 25 cm planting space of 1 m x 1 m plot. BPH and virus investation was occured narturally due to BPH outbreak along the season (DS 2010). Percentage of plant showing RRSV and RGSV symtom was measured as consideration the resistance of plant to the viruses. The results showed that the tested genotypes had high genetic variability and heritability classified as medium in the resistance to RGSV. The genotypes showed low genetic variability and heritability in the resistance to RRSV. It implies that breeder effort is feasible to develop resistant lines to RGSV. HUANGHUAZHAN and HHZ 12-Y4-Y3-Y1 are consistently resistant to RGSV and can be used as donors in further plant breeding activities. The selection of resistant individuals in populations of plant breeding material recommended to be done on earlier generations for RGSV and further generation for RSSV.
