Abstract

As an important grain legume, the improved soybean(Glycine max [L.] Merr.) adaptive to environmental changesis a valuable genetic resource. Strategy to minimize theimpact of climate effects should be underlined on soybeanproduction encompassing advanced genomics and wellpredicted future climate. Crops including soybean respondto climate change in the aspect of abiotic and bioticenvironmental factors. To predict soybean response toabiotic and biotic stresses, current progress of quantitativetrait loci (QTL) for abiotic and biotic stresses and floweringand related genomic resources could be accessed atSoyBase (http://www.soybase.org) and Phytozome(http://www.phytozome.net). As the involvement of abioticand biotic stresses modulating flowering in soybean, geneslinked to QTL for abiotic/biotic stress and flowering/maturitywere also potential for resisting the environmental changes.By mapping QTLs for flowering using one population indifferent locations (Korea and China) with distinctivelongitude, latitude, and altitude, syntenic correlationbetween these two QTLs on soybean chromosomes 6 and13 indicates the environmental specific role of syntenicregions. The information on QTL and related candidategenes may assist marker-assisted breeding and enactsoybean as a model of adaptive legume crop under abiotic/biotic stress.

Abstract

The ricebrown planthopper (BPH), Nilaparvata lugens (Stål) is amajor insect pest of rice and their infestations occur everyyear in several locations in Indonesia. The use ofinsecticides often fails to control the BPH so theirpopulations are still high that cause rice crops showhopperburn and the farmer loses the yields. Thedevelopment of insecticide resistant in BPH population isone of the factors to contribute to the failure of insecticidescontrol. We have detected the development of fieldpopulation BPH resistance to BPMC, carbofuran, MIPC, andimidacloprid, but we do not know yet the development ofresistance to other insecticides to control BPH in Indonesia.This paper will review several cases on BPH resistance toinsecticides in Indonesia and other countries that includeaspects of the development of resistance in the field and inthe laboratory, the mechanism of resistance, inheritance ofresistance, genomics of resistance, and resistancemanagement. A policy and further study is also suggested forinsecticide resistance management in Indonesia.

Abstract

Raising yield potential of modernindica varieties is essential to meet the increased demand ofrice production. This is due to increased human population,threats of climate change and degradation of agriculturalresources. The use of chromosome segment substitutionlines (CSSL) is more effective for identification of genesthose are useful for improvement of yield potential. The aimsof this study were to observe the morphological traitdifferences between recipient parent (var. Ciherang) andthree candidates of donor parent (var. Fatmawati and newplant type lines, i.e. B12743 and B11143D), to identifypolymorphic SSR markers among them and to verify F1individuals. Ciherang and B11143D showed significantdifferences on flowering time, plant height, flag leaf area,tiller number, productive tiller number, panicle length,spikelet number per panicle and 1,000 grain weight. The rateof SSR marker polymorphisms between Ciherang andB11143D was the highest, where 155 of 513 markers (30.2%)were polymorphic. Marker genotyping using threepolymorphic markers showed that 26 of 27 plants resultedfrom the cross of Ciherang х B11143D were F1. These F1plants could become the basis of CSSL panel that facilitatethe mapping of genes responsible for increasing the yieldpotential.

Abstract

Thefocus of wheat research in Indonesia is to obtained newpotential wheat lines that are adapted to low-mid elevationand heat tolerant. This study was aimed to obtaininformation on the effect of interaction of season x line xlocation and genetic variability of wheat lines in tropicalagroecosystem. This study was conducted at the Seameo-Biotrop (<400 masl) and Indonesian Ornamental CropsResearch Institute-Cipanas (>1,000 masl) experimental fieldfor two seasons. The results showed that there was an effectof interaction of season x line x location on plant height,days to flowering, number of spikelet and floret, seed/headweight, rate of grain filling, yield, flag leaf width, stomatadensity, chlorophyll b, and leaf greenness. Meanwhileseveral characters were only influenced by the interaction ofline x location, they were yield component characters, ie.empty floret percentage, number of seed/ head, 1,000 seedweight, number of head/m2 and seed/plant weight. Sevencharacters were not influenced by interaction of neitherseason x line x environment nor line x location, they werenumber of productive tillers, head length, number ofseed/head, chlorophyll a, ratio of chlorophyll a/b, totalchlorophyll, and leaf thickness. The characters that havehigh heritability and wide genetic variability for the twoanalysis models were the number of spikelet.

Abstract

Effect of gamma irradiation on rice callus dependson the irradiation dose used. Irradiation dose is one of thefactors that affect the genetic changes in the cells of plants.High doses can result in tissue death, meanwhile low doseswill result in abnormal changes in plant phenotype. The levelof sensitivity of a plant tissue against gamma irradiation isdifferent. This study aimed to evaluate the growth andregeneration of callus in various irradiation doses of gammaray. The plant materials used were mature embryos of ricevar. Ciherang and Inpari 13. This study used a completelyrandomized design with gamma irradiation treatment atdoses of 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 Gy. Eachtreatment consisted of 10 replicates with 5 embryogenic calliper bottle. The results showed that the increasing doses ofgamma irradiation increased the percentage of dead callus,inhibited callus growth, and its ability to regenerate. Thehigh percentages of callus of Ciherang and Inpari 13 thatformed green spots and adventitious shoots were mostlyobtained from controls. The percentages decreased atirradiation doses of 10, 20, 30, and 40 Gy. Moreover, the calliof Ciherang and Inpari 13 were not able to form adventitiousshoots at irradiation doses higher than 40 Gy and 30 Gy,respectively.
