Abstract

The phenomenon of heterosis provides a greatopportunity for plant breeders to gain greaterperformance and yield in the hybrids compared to theirinbred line parents. In most cross-pollinated crops likemaize, heterosis plays an important role as theperformance of the hybrids is of a great value. Heterosisgain much interest until recently and current studies stillattempt to elucidateone of these is utilizing molecularmarkers to estimate genetic distances among inbredlines followed by developing putative groups. In a welldened heterotic group, between-groups mating areexpected to produce better hybrids than within-groupsmating. Some studies of marker-aided heterotic groupdevelopment resulted in functional heterotic groups;while some other reported that the groups failed toprovide evidence of heterosis in the hybrids.Considering the prediction of hybrids' performance willdepend on genetic background of inbred lines, andmarkers technology are continuously improved, there isstill a good opportunity to obtain useful heterotic groupsfor a particular breeding population.Keywords: maize breeding, genetic distance, heterosis,molecular markers.

Abstract

Dendrobium mannii and Dendrobium mirbelianum were rare and endangered orchid species. In vitro micro propagation could be used to conserve and proliferate these species. The aims of this study were to determine the effects of chitosan on proliferation of the protocorm-like-bodies (PLBs) of in vitro grown Dendrobium mannii and D. mirbelianum. Chitosan has been reported as an important component to promote orchid growth in vitro. In this study chitosan was included in the in-vitro media at the concentrations of 0, 1, 2, 3, and 4 mg.L-1. The highest PLBs formation, clump diameter, and fresh weight on D. mannii were obtained from explants cultured on medium supplemented with 1 mg.L-1 chitosan. After 14 weeks of culture, fresh weight, clump diameter and average number of PLBs of D.mannii were 29.52 %, 33.00 % and 35.88% greater at chitosan (1 mg.L-1) compared to control media.  D. mirbelianum treated with low chitosan concentrations (1 and 2 mg.L-1) had 65.71% more leaves than those without chitosan treatment. Chitosan, however, had an adverse effects on growth of both species at  4 mg.L-1. Medium contain 4 mg.L-1 chitosan induced PLBs proliferation of D.mannii, but inhibited PLBs proliferation of D.mirbelianum.  These results suggested that chitosan had important roles in PLB proliferation and could be used for the propagation of D. mannii PLBs in vitro. Keywords: rare orchid species, in-vitro

Abstract

The demand of sweet corn in Indonesia has been increasing; therefore  breeding  efforts  are  aimed  for high yielding sweet corn varieties with superior quality. This research was aimed to evaluate the yield of five newly developed sweet corn hybrids compared to the commercial varieties. The research was conducted  at  the  Leuwikopo  experimental field of IPB, and Laboratory of Genetics and Plant Breeding, Department of Agronomy and Horticulture, IPB Darmaga campus from September to December 2015. The experiment was arranged in a completely randomized block design with three replications. Five new sweet corn hybrids, “ JM8 x JM2”, “JM8 x JM7”, “JM16  x  JM8”,  “JM17  x  JM6”  and  “JM17  x JM7”, and four commercial varieties, “Bonanza”, “Master Sweet”, “Sugar 75” and “Sweet Boy”, were tested. The results showed that the new hybrids vary in plant height, days to anthesis, days to silking, ear height, ear length, sugar content, number of kernel rows, the weight of husked ear, and number of ears per plant, downy mildew infected area, and productivity. F1 of “JM8 x JM2” has longer ears than “Master Sweet” and “Sugar 75”, higher sugar content than “Sugar 75”, and higher resistance against downy mildew than “Master Sweet” and “Sweet Boy”.

Abstract

Corn kernel is one of the most important characters that correlate with corn yield and quality. Sweet corn kernels can be distinguished by its color which is either yellow and white or pale yellow. Sweet corn breeding by crossing genotypes with different kernel colors will affect the inheritance pattern of kernel color. The aims of this research were to understand the inheritance pattern in sweet corn kernel color by crossing yellow and pale yellow color with red and purple corn kernels using qualitative and quantitative approaches. Genetic materials consisted of P1 (JM2 and JM4) and P2 (Red and Purple) and F1, F2, F3, and F1 reciprocals. P1 consists of JM2 and JM4 with flint shape with yellow and pale yellow color; P2 consists of Red and purple with non-yellow colored kernel and flint shape. The results showed maternal effect influenced the kernel color, but did not affect the kernel shape. Epistatic effects were found in kernel shape but it was co-dominant on kernel color inheritance. Broad-sense heritability values were high for all quantitative variables. Keywords : color, heritability, pale yellow, purple, red, shape

Abstract

ABSTRACTBreeding of melon requires the availability of genetic diversity and extensive evaluations of the genetic materials. Evaluations on fruit quality and yield potential are among the important steps in melon breeding. This research was aimed at studying the genetic diversity of 17 melon genotypes based on fruit traits and identifying the potential genotypes to be used as genetic materials in melon breeding programs. The research was conducted from August to October 2015 at the IPB Experimental Station Tajur II, South Bogor, 250 m above sea level. The experiment was arranged in a single factor of randomized complete block design with four replicates. Results of the research showed that genotype effects were significant for all observed traits except for days to hermaphrodite flowering. Traits having broad sense heritability estimates greater than 50% were days to male flowering, days to harvest, fruit length, fruit diameter, flesh thickness, fruit rind thickness, fruit weight, and sugar contant. P21 and P19 genotypes were potential for fruit weight and sugar content, while P2 was potential for fruit weight and P12 for sugar content only. Fruit weight showed significant positive correlations with fruit length, fruit diameter, flesh thickness, and fruit rind thickness. Clustering based on morphological traits generally separated reticulatus and inodorus genotypes into different groups.Key words: correlation, heritability, simultaneous selectionABSTRAKPemuliaan tanaman melon memerlukan ketersediaan keragaman genetik dan evaluasi yang ekstesif pada materi genetik yang digunakan.

Abstract

Determination of secondary characters during stagnant flooding (SF) is considered important for breeders as the selection criteria in developing SF rice tolerant varieties. Aims of this study were to find agronomical variation and to determine secondary traits that were related to SF tolerance among the rice varieties. Experiment was conducted at Indonesian Center for Rice Research in 2015. Ten rice genotypes were grown in RCBD with three replications under normal and gradual flooding conditions. Agronomic data were gathered and analysed using combined ANOVA, correlation, multiple linear regressions and genetic variability. Results showed that 92.3% variance of stress tolerance index (STI) were presented from a linear model involving weight of 100-grains, panicle length, stem diameter, intensity of leaf green color and stem length. Stem length, intensity of leaf green color, and panicle length had broad genetic variability and high heritability these characters were important criteria when selecting the traits under flowing stress. Number of productive tillers was correlated with grain yield under SF and highly heritable, thus considered as one of determining characters for stagnant flooding tolerance. Based on STIStd, Ciherang and INPARI 30 showed more adaptive performance, while IR 42 had the least when grown under 50-60 cm stagnant water depth.

Abstract

The need for domestic wheat grains tends to increase, and one of the efforts to face this situation is the assembly of tropical wheat varieties. The approach taken through this research is hybridization followed by several generations of selection. This study aimed to predict heterosis and the crossed combinations that possibly produced transgressive segregants. The experiment was conducted from August 2016 to May 2017 at the experimental station of the Indonesian Ornamental Plants Research Center, Cipanas (1100 m asl), Cianjur Regency, West Java Province. The genetic materials were seven genotypes, namely Guri1, Guri2, Guri3, Guri6, HP1744, IS-Jarissa, and Vee, crossed with the Selayar variety. This experiment used a randomized complete block design with three replications. The treatment was 15 wheat genotypes (seven F1 genotypes and eight parent genotypes), so there were 45 experimental units. There were yield and yield component observations. The results showed that several characters in each F1 combination of crosses had a higher or lower mean value than their parents. There is a combination of crosses that have a high heterosis value. The action of genes that control yield and yield components of wheat are overdominant, partially dominant, and partially recessive gene actions. The cross combinations of Guri3/Selayar, Guri6/Selayar, Jarissa/Selayar, HP1744/Selayar, and Vee/Selayar have a greater chance to produce transgressive segregants than the others.
