Abstract

The ability of seed to maintain seed quality during storage is called seed vigor. Accurate method for seed vigor testing of pepper seeds is necessary to accurately determine seed storability during seed distribution. The aim of this research was to determine the best accelerated aging method (AAM) of pepper seed. Freshly harvested seeds of Capsicum annuumL., IPB C9 genotype were used in this study. The experiment used randomized complete block design (RCBD) with three replications. The experimental treatments were seed vigor testing methods i.e. natural deterioration test at room temperature in controlled humidity (RH 90-95%), and four AAM (hot water 60 ºC, methanol 20%, ethanol 20%, and high temperature at 40 ºC). The best method was selected using analysis of variance, coeficient of variance, regresion dan t student analysis. AAM using 20% methanol at periods of 0, 2, 4, 6 and 8 hours was the best method of seed vigor testing for pepper seed. Keywords: accelerated aging, deterioration, ethanol, methanol, high temperature

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

Mutants of Spathoglottis plicataBlume were obtained from plants treated with Gamma Irradiation at 30-100 Gray. The mutants showed variations in the flower morphology. The objective of this experiment was to identify genetic variations of orchids S. plicataand its mutants using inter-simple sequent repeat (ISSR) markers. The amplified product of 10 ISSR primers produced 360 bands and 71 ISSR of the loci (90.14%) were polymorphic. The coefficient of similarity and principal component analysis produced five major groups with similarity coefficient of 0.68. The goodness of fit correlation matrix value reached 0.91. Therefore the ISSR isa good marker for identification of S. plicatamutants.Keywords: gamma irradiation, ISSR marker, mutant, orchid

Abstract

The objective of this research was to analyze the combining ability of nine tropical maize lines from PT. BISI International, Tbk’s collections across two locations. The research used a complete diallel mating design according to Griffing’s method 1. Randomized completely block design was used as an experimental design with three replications in each location, Kediri and Nganjuk, East Java. Result of the combining ability analysis revealed that location effect was significant for all traits. Additive gene effects were more important in controlling plant height, ear length, ear diameter and 1,000-grain weight while non-additive gene effects were more important in controlling days to harvest, ear weight per plot and yield potency. Good combiners across locations for days to harvest were Sr-1#247 and Sr-1#086. Sr-1#001 and Loe#187; Pron#077 and Loe#057; Pron#142 and Loe#187; Loe#187 and Loe#057; Sr-1#001 and Loe#187 were a good combiners for ear length, ear diameter, 1,000-grain weight, ear weight per plot and yield potency, respectively. Best specific combinations for several important traits were generated from parent lines with high x low GCA. Sr-1#001xLoe#055; Loe#187xLoe#055 and Loe#057xLoe#055 were the best for ear weight per plot and yield potency.Keywords: combining ability, diallel, G x E interaction, tropical maize

Abstract

Bacterial wilt and fruit cracking are serious problems in tomatoes cultivation in the lowland area. This research aimed to evaluate the yield of M4 generation of tomatoes in the field and the incidence of bacterial wilt disease and fruit cracking in low altitude. The research was conducted at the IPB Experimental Field in Leuwikopo, Dramaga, Bogor, from December 2015 to April 2016. The experiment used a randomized complete block design with three replications. The material consisted of 15 M4 genotypes and two controls (Berlian and Kefaminano 6). The results showed that genotype of M4/495 Lombok 1-9-2 (U2) has high? productivity. Genotype M4/990 Lombok 1-5-1 (U1) has? high weight? per fruit and resistant to fruit cracking. Genotype M4/495 GL2-8-10 (U2), M4/495 Kemir 1- 4-7 (U3), M4/495 STBGL 1-2-3 (U1) M4/990 Lombok 1-5-1 (U1), and? M4/495 STBGL 1-2-9 (U1) have the lowest incidence of bacterial wilt (0.00%). Two genotypes which have high productivity and resistant to fruit cracking are M4/495 Lombok 1-9-2 (U2) and M4/990 Lombok 1-5-1 (U1), and to be evaluated in a preliminary yield trial.
