Judul: Characterization of Doubled Haploid  Eggplant (Solanum melongena L.) Lines Obtained from Anther Culture
Abstrak: Pendekatan teknologi dihaploid (doubled haploid/DH) melalui kultur antera berhasil mempersingkat perolehan galur homozigot terhadap komoditas terung (Solanum melongena L.). Penelitian ini bertujuan mengidentifikasi galur-galur dihaploid terung hasil kultur antera yang berpotensi dikembangkan sebagai tetua persilangan hibrida. Penelitian ini mengkarakterisasi 11 galur dihaploid terung dan 3 varietas cek. Pengamatan kuantitatif dan kualitatif dilakukan menggunakan Panduan Pengujian Individu oleh PPVT 2007. Pengolahan data kuantitatif menggunakan analisis ragam dan jika signifikan dilanjutkan dengan uji Tukey BNJ a 5%. Data kualitatif dijelaskan secara deskriptif. Analisis gerombol mengelompokkan genotipe-genotipe berdasarkan kemiripan karakter melalui dendrogram. Hasil penelitian menunjukkan bahwa genotipe uji terung menunjukkan keragaman pada seluruh karakter kuantitatif selain umur akhir panen, serta keragaman karakter kualitatif yaitu tipe tumbuh, lekukan tepi helai daun, warna mahkota bunga, bentuk umum, warna kulit buah saat masak panen, kelengkungan, tambalan, rasio panjang banding diameter, dan bentuk ujung buah. Genotipe terung dikelompokkan menjadi empat gerombol. Pro-AM1, Pro-AM38, dan Hit-AM30 merupakan galur yang potensial sebagai tetua persilangan dengan karakter hasil yang baik., The doubled haploid (DH) technology approach through anther culture succeeded in shortening the production of homozygous lines of eggplant (Solanum melongena L.). This research aimed to identify doubled haploid lines of eggplant obtained from anther culture that have the potential to be developed as parents for hybrids. This study characterized 11 doubled haploid lines of eggplant and 3 check varieties. Quantitative and qualitative observations were carried out using Individual Test Guidelines by PPVT 2007. Quantitative data were analyzed using analysis of variance and if significant it was continued with Tukey’s HSD a 5%. Qualitative data were explained descriptively. Cluster analysis grouped the tested genotypes based on character similarities through a dendrogram. The result of the research showed that doubled haploid eggplant lines varied in all quantitative characters except the end of harvest age, as well as qualitative characteristics namely growth type, curve of leaf edge, color of flower corolla, general shape, color of fruit skin when ripe for harvest, curvature, patch, length to diameter ratio, and fruit tip shape. Eggplant genotypes are divided into four clusters. Pro-AM1, Pro-AM38, dan Hit- AM30 are potential lines as parents for hybrids with good yield characters.

Abstrak: Eggplant breeding has not been done intensively despite available high genetic diversity, and increased public interest, so it is an opportunity and a challenge to be able to assemble a variety with proper breeding methods. Evaluation on genetic diversity, heritability and correlations between characters in eggplant (Solanum melongena L.) conducted in Kediri, East Java, in January - August 2012 used 30 genotypes collection of PT. BISI International Tbk from Indonesia (8 genotypes), Philippines (5 genotypes), 15 genotypes from China and India (2 genotypes), arranged in Randomized Complete Block Design with 3 replications. The results showed that there was phenotypic variability among 30 eggplant genotypes derived from several source populations. Genotypes from India showed different characters in the age of flowering, fruit length, fruit diameter, fruit weight and number of fruits per plant. There were characters which had high broad sense heritability with high genetic advance i.e. fruit length (92.84%, 43.3%), fruit diameter (68.71%, 45.12%), fruit weight (86.18%, 52.77%), and the number of fruits per plant (62.74%, 47.77%). There were 14 positive and 8 negative significant correlation coefficiens between the main characters. Based on principal component analysis (PCA), combination of PCA I and PCA III gave 42.92% of variability, it separated genotypes into 3 groups, i.e. BEPA05 in group I, BEPE97 in group II and 28 genotypes in group III. . Full diallel cross by Griffing method I made on 8 genotypes (BEP 01, BEP04, BEP 06, BEP 08, BEP 10, BEP11, BEP 12) to test the general combining ability, specific combining ability and genetic parameter. The experiments were performed used 64 genotypes consisted of 28 F1, 28 F1R and 8 parents, used Randomized Complete Block Design with 3 replications in November 2012 - April 2013. Characters of flowering age, harvesting age and fruit weight per plant was affected by the action of a dominant gene because it had specific combining ability value (SCA) higher than the general combining ability (GCA). Plant height, fruit length, fruit diameter, fruit hardness, weight per fruit and number of fruit per plant characters expression was influenced by additive gene action because it had GCA higher than SCA. BEP 04 genotypes have relatively more consistent with SCA and GCA values higher than other genotypes. No interaction of genes on the performance of the characters because the value of b (Wr, Vr) were not significantly different from 1 except fruit weight and number of fruit per plant. The genes distribution for the traits studied unequal on each parents. Fruit length and fruit hardness were controlled by at least one group of genes. Fruit diameter, weight per fruit and number of fruit per plant at least two groups of genes, flowering and plant height were controlled by at least three groups of genes. Harvesting was controlled by at least four groups of genes and the weight of fruit per plant was controlled by at least 5 groups of genes. Broad sense heritability of all the characters were high (h2BS > 50%). All characters had high heritability narrow sense except days to flowering (27%), harvesting (49%), and weight of fruit per
