Abstract

ABSTRACTThe  objective  of  the  research  was  to  study  the  factors  effecting  unfilled  grains  in  intersubspecific  hybridization.  The  research  was  conducted  at  Muara, Bogor  from  April  2005  to  February  2006.  The  materials  used  in the research were  ten  F1 hybrid  combinations.  The evaluation was done by crossing the hybrids to Ciherang and it was resiprocal. A randomized block design with three replications were arranged in greenhouse. The results showed that five cross combinations produced higher unfilled grains and lower pollen fertility due to defective male gamets. The cross combinations that is Akitakomaci/IR64, Akitakomaci/Wayrarem, Akitakomaci/Salumpikit, Akitakomaci/Ketupat, and Akitakomaci/Kewal. Another five cross combinations produced normal pollen fertility but high unfilled grains. The high unfilled grains of four cross combinations was due to defective female gamets. The cross combination that is IR64/Sirendah Pulen, IR64/Lampung Putih, IR64/Lampung Kuning, and IR64/Mesir.  The other cross combination was due to defective male and female gamets  namely IR64/Brentel. Key words:  Unfilled grain, F1 hybrids, male gamets, female gamets

Abstract

The objective of this research was to determine the trait variance in black soybean lines in terms of yield and yield components. The materials used were F8 lines generated from hybridization of two local varieties, i.e. black seeded Ceneng and greenish yellow seeded Godek, and then selected under single seed descent method, except  SC-39-1, SC-62-2 and GC-74-7 that were generated through bulk selection method. The results showed that the traits between plant genotypes were significantly different, except number of productive node and number of unfilled pod. Total variance was contributed more by number of filled pod, seed weight per plant and 100 seed weight.  Seed weight per plant and 100 seed weight had high heritability with genetic variance and broad-sense heritability which were significantly different from zero. These characters are important for further selection to improve yields of black soybean lines.Keywords: black soybean lines, broad sense heritability, total variance

Abstract

The objective of the research was to identify RAPD markers linked to QTL related to agronomic traits of soybean under low-light intensity condition. The genetic material used in the QTL analysis based on RAPD Markers were Ceneng, Godek, and F6 RILs derived from hybridization between Ceneng (tolerant parent) and Godek (sensitve parent). The results of molecular analysis showed that 9 primers were polymorphic and linked to the tolerant parent. Primers produce 14 RAPD markers which were polymorphic and linked to the tolerant parent. The markers were distributed into a linkage group that containing seven markers. RAPD Markers (OPE15-800, OPM20-800) were linked to two QTL controlling number of productive node and seed weight, respectively. The marker linked to the tolerant parent could be used as a marker assisted selection for high-yielding soybean lines under low-light intensity

Abstract

Water use efficient varieties in rice may have good opportunity in term of economic value and scarcity of water. This study was conducted to determine water consumption among rice genotypes that conventionally cultivated as low land (IR64, IPB97-F-15, Ciherang, Mentik Wangi, and Rokan hybrid), up land (Jatiluhur, Silugonggo), and amphibian type (Way Apo Buru, that could be planted both as lowland and up land). Rice seedlings at 14 days old were transplanted in a plastic container containing 83 kg of air dried soil, 1 plant per whole and 6 plants per container. The experiment was conducted in a vinyl house, using randomized complete block design with three replications. During rice growth, water table was maintained at 2 cm above soil surface, and water was added and recorded weekly. The results showed that varieties reveal production components and yield were different significantly. Water consumptions among varieties were significantly different, ranged from 15.93 L plant-1 for IR64 to 24.13 L plant-1 for Jatiluhur, or equal with 3,639 to 4,827 m3 ha-1. Jatiluhur was the most efficient variety in using water. This finding may guide us to explore benefit of water use efficient variety as sustainable option in water management of rice cultivation.

Abstract

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

Abstract

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
