Aluminum (Al) toxicity and blast disease are the most important yield-limiting factors for upland rice production in acid soils. The objective of this experiment was to examine the contribution of accumulation of Silicate (Si), Nitrogen (N) and Al in plant tissue on Al tolerance and blast disease resistance in upland rice. The experiment was arranged in a split-split plot design with 2 replications. Main plots were randomly assigned to blast treatment (control and inoculation to blast fungi). Subplots were assigned to control box (lime 1.5 AlEC) and another acid soils (no lime) box and sub-subplots were assigned to the tested genotypes. The result of the experiment showed that leaf blast disease resistance in rice cannot be solely explained by Si or N content in shoot tissue. The resistant to leaf blast disease might be attributed by high ratio Si/N weight in shoot. Al tolerance was ascribed by low reduction in root growth, high shoot dry weight, high Si content in shoot, and as well as high of Si/Al ratio in root. Key words: Al-tolerance, blast disease, upland rice, Si/Al ratio

Sorghum is one of high value commodities for food and energy security due to its wide adaptation. The objectives of this research were to study some genetic parameters of sorghum agronomic traits grown under acid soil conditions and to select aluminum-tolerant sorghum mutant lines. The selection was conducted in an augmented design with 61 lines at the field research station of B2TP-BPPT Lampung. Genetic materials used were mutant lines developed throught gamma irradiation. The results showed that there was significant differences among the mutant lines for some agronomic characters observed. The heritability estimates for agronomic characters were classified as intermediate to high. Selection based on seed weight and biomass production resulted three best sorghum mutan lines i.e ZH30-29-07, ZH30-30-07, and ZH30-35-07. These lines showed the best yield and biomass production under acid soil condition. Key words: sorghum, acid soil, heritability, selection

Twenty seven land races of tropical japonica rice were test-crossed with a 'WA' type cytoplasmic male sterility (CMS) line IR58025A to evaluate their fertility restoration ability. Based on pollen fertility and spikelet fertility of their F1 hybrids, genotypes are classified into maintainer or restorer. The result showed frequency of maintainers among genotypes was higher than restorers. Four genotypes, i.e., Ase Lapan, Ase Mandi, Hawara Bunar and Lampung Kuning were designated as maintainers. These maintainers possess a number of desirable traits such as pest resistance and abiotic stresses tolerance; thus they will be useful for improving parental lines of hybrid rice. Key words: Land race, test cross, fertility restoration

Aluminum (Al) toxicity is the main yield-limiting factor for maize growing on acid soils of tropical regions. This experiment was conducted to screen maize (Zea mays L) genotypes under Al stress in culture solution. The experiment was arranged in a split plot design with three replications. The main plots were Al concentrations (0, 2.5, 5 10, 20, and 40 ppm Al), and the sub plots were 22 maize genotypes. The results indicated that the genotype AMATL-(HS).C2, SATP-(S2)-C6-S0, MRSS-1(S1).C1-29-1, and MRSS-1(S1).C1-57-1 were more tolerant to Al-toxicity than the other genotypes including Antasena. The growth of Al-tolerant genotypes under low concentration of Al (2.5 ppm Al) was stimulated. The Concentration of 5 - 10 ppm Al in nutrient solution was adequate to separate genotypes between tolerant and sensitive genotypes in screening maize genotypes under Al stress. Relative net root length and relative root length were the best variable to be used as Al-tolerance indicators. Key words: Maize, Al-tolerance, Al-toxicity

High-yielding variety is one of the targets in soybean breeding program. High-yielding variety could be developed through simultaneous selection. Simultaneous selection using selection index was more efficient than selection based on an individual trait only. Objective of the research was to select agronomic characters for construction selection index on 11 soybean populations F6 generation based on correlation analysis, path analysis, and heritability. The correlation analysis showed that number of branch, number of total nod, number of filled pod, number of unfilled pod, number of total pod, and percentage of filled pod have positively and significantly correlated with yield per plant. Based on path analysis, characters number of branch, number of unfilled pod, and number of filled pod have positive direct on yield per plant. The result also showed that number of filled pod has maximum positive direct effect on yield per plant. Generally, number of total nod, number of filled pod, number of total pod, and percentage of filled pod have higher heritability than other characters. Key words: Soybean, correlation, path analysis, heritability, selection index

Aluminum (Al) toxicity is one of the most important yield-limiting factors for upland rice grown on acid soils. Since many small farmers may have difficulty in soil liming, the genotypes tolerant to soil acidity and aluminum toxicity should be developed. Anther culture can substantially speed up new variety development through recombination of parental characters in early generations and immediately homozygous lines were upon chromosome doubling. The Doubled haploid (DH) rice lines were screened under both nutrient solution containing either 0 or 45 ppm Al and acid soils containing either low or high-Al saturation. The relative root length (RRL) was determined at 14-day-old stage to characterize genotypes for Al-tolerance in nutrient solution. The relative grain weight (RGW) was determined to characterize genotypes for Al-tolerance in soils conditions. The results of this study indicated that Al reduced root elongation. The differential tolerance for Al among genotypes was found to be highly significant for RRL. Of the 120 genotypes tested, 16, 77 and 27 genotypes were found to be Al-tolerance, moderate and sensitive in term of RRL respectively. KRGM4, JTGR13, JTGR17, JTGR18, JTKR1, JTKR5, GRGM4, GRGM6, GRGM9, GRGM14, GRGM25, GRJT11 and SGJT27 lines were consitently Al-tolerance under both nutrient solution and acid soils. The RRL of doubled haploid upland rice lines in nutrient solutions were strongly correlated with RGW in acid soils. Key words: Rice, doubled haploid, aluminum tolerance, relative root length, relative grain weight

The main objective of this study was to identify the leaf morpho-physiological characters as markers for adaptation of soybean to low light intensity. The field experiment was conducted using split plot design with 3 replications. First factor was soybean genotype consisted of shade tolerant genotypes (Ceneng, Pangrango) and sensitive genotypes (Godek, Slamet). Second factor was low light intensity consisted of: L0 = control (under full sun light), L1 = 5 days under 50% shading (exposed after 21 days after planting/DAP), L2 = 5 days under dark condition (exposed after 21 DAP), L3 = 3 days 50% shading + 5 days sun light (exposed after 18 DAP), dan L4 = 3 days 50% shading + 3 days sun light + 5 day dark conditions (exposed after 15 DAP). The 50% shading was made artificially using black plastic paranet with 50% light transmitted. Results of this study showed that under the conditions of low light intensity, leaf morpho-physiological characters of soybean that could be used as markers for adaptation were leaf area, specific leaf weight, and chlorophyll content. Leaves of shade tolerant genotypes were wider and thinner and also contained higher chlorophyll especially for chlorophyll b than that of shade sensitive genotypes under low light intensity. Key words : Low light intensity, tolerant genotype, leaf area, chlorophyll, specific leaf weight

The objective of this study was to analyze the inheritance pattern of soybean adaptation to shade stress based on leaf morpho-physiological characters. Genetic materials used in this study consisted of 22 plants of low irradiance (LI)-tolerant genotype (Ceneng) and 22 plants of LI-sensitive genotype (Godek); 21 plants of F1 (Ceneng x Godek); and 114 plants of F2 populations (derived from F1). These populations were planted under shading of paranet 50%. The population was arranged in a Randomized Complete Block Design with two replicates. Analysis of inheritance of soybean adaptation involved estimation of heritability (broad sense) and gene action. Results of this study showed that: adaptation of soybean to low light stress based on characters of yield per plant was highly heritable (68% of broad sense) with partial dominant mode of action. Characters of leaf area and specific leaf weight were highly (68% of broad sense) and moderately (48% of broad sense) heritable, respectively, with additive mode of action. Soybean adaptation based on leaf physiological characters (chlorophyll contents) was highly heritable (70% - 86% of broad sense) in epistatic mode of action. Key words: Soybean, leaf morpho-physiological character, heritability, gene action
