Abstract

The aim of this experiment was to evaluate the pattern of yield improvement of Jatropha curcas L. of West Lombokecotype at dry land of North Lombok, West Nusa Tenggara during four years production cycle. The experiment was conductedin randomized complete block design (RCBD) using three types of propagules (i.e., stem cutting, seed, and seed followed bypruning after transplanting) and three replications from November 2006 to November 2010. The results showed that yieldwas increased as plant age increased. Plants cultivated during rainy season had higher yield compared to those cultivatedduring dry season. However, the oil content of nuts was slightly higher when harvested in dry season than in rainy season.Yield was also affected by plant material used. In the fi rst year, plants propagated by stem cutting had the highest yield. Inthe second, third, and fourth year, plants propagated from seed followed by pruning produced the highest nut dry weight.During four years production cycle, yearly yield improvement was about 2-3 times than the previous year and did not followthe geometrical progression based on dichotomy branching pattern of Jatropha.Keywords: dry land, productivity, pruning, seed oil content, type of propagule

Abstract

Productivity of Amorphophallus muelleri is considered low. Thus, pot experiment was conducted at the CikabayanExperimental Farm, Bogor Indonesia during rainy season November 2007 to July 2008, in order to determine the optimumfertilizer dose for A. muelleri under 50% shading net. Treatments consisted of four doses of nitrogen (0, 50, 100 and 150 kgha-1 N) and three doses of potassium (0, 50 and 100 kg ha-1 K2O). The results showed that application of N and K fertilizerssignificantly increased vegetative growth, i.e., number of leaves, number of leaflets and second leaf size, but did not affectharvesting time. Fresh weight and dry matter content of daughter corm were significantly affected by N and K applications.Combination of 50 kg ha-1 N and 100 kg ha-1 K2O resulted in higher corm weight than other treatments. It is evident that theapplication of nitrogen and potassium is important in A. muelleri.Keywords: disease infection, iles-iles, Indonesian konjac, nitrogen, potassium

Abstract

Anther culture is useful tool in rice breeding. The technique shortens the time to obtain full homozygous plant in just one generation. Information related to genetic variability among the regenerants is important for further analysis including selection activities. The objective of this study was to analyze agronomic character variability and yield potential among doubled-haploid lines (DH0) derived from anther culture. This study was carried out in Center for Agricultural Biotechnology and Genetic Resources Research and Development (BB Biogen) from October 2016 to February 2017. The experiment was arranged in randomized complete block design (RCBD) with three replications. Forty eight doubled haploid lines derived from anther culture and three check varieties were evaluated. The results showed high genetic variability as well as broad sense heritability (more than 90%) for all variables tested. Several lines showed superior agronomic characters compared to check (Ciherang, Inpari 18, Inpago 10). Anther culture could generate high genetic variability for further selection.Keywords: anther culture, broad sense heritability, haploid technology

Abstract

Salinity has become a serious problem in the production of food crops in Indonesia, especially in coastal areas. Mungbeans is one of commodities which can be grown in coastal areas during the dry season. Research to evaluate tolerance of mungbean genotypes to salinity stress was conducted on saline soil (EC 11.4 dS m-1) at Lohgung Village, Brondong Sub District, Lamongan District during dry season May-July in 2016. A 100 of mungbean genotypes were evaluated using a randomized block design, replicated twice. The majority of the genotypes (82%) were categorized between sensitive to very sensitive to salinity stress. All of the genotypes grew normally to generative phase and produced 2-9 pods per plant with seed yield ranged 0.04-0.60 ton ha-1. The tolerant genotypes had higher plant height, stover weight, and yield than the sensitive genotypes. Six genotypes indicated as very tolerant to salinity stress (EC: 9.24 to 15.06 dS m-1) i.e., MLG 1065/Vima1-279, MMC 464c-gt-4-0-3, MMC 678-8c-gt-5, Vima 1/MLG 1065-286, MLG 1065/Vima1-276 and Vima1/Sampeong//Vima1-249. Seven genotypes indicated as tolerant to salinity stress i.e., Vima1/MLG1065-290, MLG1065/Vima1-272,  MLG1065/Vima1-274, Vima1/MLG 1065-287, Vima1/MLG 1065-276, MMC 267c-mn-1-1-11, and VIMA 1/MLG 1065-288. These selected genotypes were potential to be developed into new mungbean variety tolerant to salinity.Keywords: electrical conductivity, growth, yield, selection, Vigna radiata

Abstract

Observation and identification of rice germplasm with advanced traits are important activities in the process of obtaining a variety of rice because every genotype will show unique characters. Genotype derived from breeding program as anther culture need to be characterized to identify the doubled haploid lines that are potential to be developed in red rice breeding. This research was aimed to obtain agronomic characters of doubled haploid lines of red rice. Materials used were 59 genotypes, i.e., 57 doubled haploid (DH0) lines with red grain and 2 check varieties (Inpari 24 and Aek Sibundong) as control. The experiment used a randomized complete block design with three replications. The results exhibited there was agronomic variation among DH0 of red rice lines. Variance analysis showed that genotype affected most characters, except for grain dry weight per hill. Plant height, number of productive tiller, harvesting age, panicle length, number of grains per panicle, and number of filled grain per panicle can be used as a reference for effective selection to develop high productivity of red rice variety.
