Abstract

Banyaknya kendala yang membatasi pertumbuhan dan perkembangan tanaman seperti kemasaman tanah, keracunan unsur mikro dan kahat unsur makro mengakibatkan hasil biji di lahan kering masam tidak setinggi di lahan optimal. Oleh karena itu awal dari perakitan kedelai untuk lahan kering masam terutama diarahkan untuk perbaikan hasil biji. Secara genetik perbaikan hasil biji menghadapi kendala berupa rendahnya keragaman genetik dan heritabilitas yang tergolong sedang. Genotipe kedelai toleran lahan kering masam biasanya memiliki ukuran biji yang tergolong kecil. Di lain pihak, petani dan industri berbahan baku kedelai lebih senang menggunakan kedelai berbiji besar daripada kedelai berbiji kecil, sehingga selain perbaikan hasil biji juga diperlukan perbaikan ukuran biji. Kendala yang juga dihadapi dalam perbaikan ukuran biji adalah heritabilitas tergolong sedang, namun keragaman genetiknya tergolong luas. Kemajuan yang dicapai dalam perakitan varietas kedelai toleran lahan kering masam saat ini berpeluang untuk diperolehnya kedelai berdaya hasil tinggi dan berbiji lebih besar daripada varietas yang sudah dilepas

Abstract

Ekstensifikasi ke luar pulau Jawa merupakan salah satu cara dalam usaha peningkatan produksi kedelai di Indonesia, karena masih terdapat banyak lahan yang belum termanfaatkan secara optimal. Salah satu lahan tersebut adalah lahan pasang surut yang mencapai 20,192 juta hektar. Dalam pengembangan kedelai di wilayah ini, diperlukan suatu varietas adaptif lahan pasang surut karena habitat kedelai sebenarnya adalah di lahan yang bebas dari genangan air. Strategi pembentukan kedelai adaptif lahan pasang surut mengacu pada pemecahan masalah utama, yaitu genangan diikuti dengan pemecahan masalah lainnya seperti kemasaman tanah serta defisiensi unsur hara makro dan toksisitas unsur hara mikro. Oleh karena itu lingkungan seleksi memegang peranan utama dalam pembentukan varietas adaptif ini. Selain itu, kriteria seleksi juga sangat penting karena menentukan pemilihan galur-galur adaptif. Metode identifikasi juga penting karena menentukan mekanisme ketahanan yang dimiliki oleh genotipe terpilih, dan dapat dilakukan berdasarkan pada karakter fisiologis, morfologis, dan agronomis. Pada dasarnya arah pengembangan merupakan faktor utama strategi pembentukan varietas adaptif ditetapkan.

Abstract

Alih fungsi lahan pertanian produktif dan perubahan iklim global menyebabkan menurunnya produksi kedelai (Glycine max Merr.) di Indonesia. Perluasan areal tanam kedelai untuk mengatasi hal tersebut pada umumnya mengarah pada lahan-lahan suboptimal, di antaranya adalah lahan kering. Oleh karena itu, perakitan varietas unggul kedelai toleran kekeringan menjadi salah satu faktor penentu keberhasilan perluasan areal tanam di lahan tersebut. Dalam perakitan varietas kedelai toleran kekeringan, mekanisme toleransi kedelai terhadap cekaman kekeringan memegang peranan penting, karena berhubungan dengan karakter-karakter yang mendukung toleransi tersebut. Pada umumnya karakter yang berhubungan langsung dengan toleransi kekeringan adalah karakter fisiologi dan morfologi. Namun, dalam pemuliaan kedelai, hasil biji merupakan karakter yang paling penting. Dengan demikian, perakitan varietas unggul kedelai toleran kekeringan sebaiknya dilakukan dengan menggabungan karakter fisiologi, morfologi, dan agronomi; karena ketiga karakter tersebut pada umumnya tidak bertautan secara genetik. Dengan penggabungan ketiga karakter tersebut penurunan hasil akibat cekaman kekeringan dapat ditekan.

Abstract

ABSTRACTGenotype x environment interaction always presents in soybean multilocation trials in Indonesia. The objective of the research was to determine the performance of yield and yield components of soybean promising lines in two locations. A total of 11 promising lines, and three check varieties (Tanggamus, Wilis, and Anjasmoro) were evaluated in NTB and DIY in dry season 2013. The design was randomized complete block design with three replications. The results showed that yield and yield components were influenced by locations, genotypes and genotypes x locations interaction, except for days to maturity which was not influenced by the location. Number of filled pods had a significant positive correlation with grain yield of soybean. TGM/Anj-773 line had high average yield at two locations and higher than the check variety (Tanggamus).Keywords: correlation, genotype x environment, Glycine max

Abstract

Performance of soybean growth and development is influenced by environmental conditions. On similar soil fertility conditions but different environmental conditions such as rainfall will also lead the changes in the performance of the plant. The research aimed to study the agronomic performance of the potential soybean lines in two different drought acid land agroecologies. The experiment was conducted at the South Lampung Tegineneng experimental station and East Lampung Taman Bogo experimental station from February until May 2013. The South Lampung Tegineneng experimental station has a pH of 5.50 and an average rainfall of 89 mm per month, and The East Lampung Taman Bogo experimental station has a pH of 5.12 and an average rainfall of 213 mm per month. The experiment consisted of 10 soybean lines adapted acid land and two check varieties. The experiment was arranged in randomized completely block design with four replications. The least significant different test (LSD) at ? = 0.05 was used to calculate significant differences among all treatments. The results showed that rainfall influenced agronomic performance of soybean more than soil acidity. The yield performance in South Lampung was lower than in the East Lampung. Four genotypes produced higher grain yield than the Tanggamus variety in both locations, i.e. Tgm/Anj-862, Tgm/Anj-784, Tgm/Anj-888 Tgm/Anj-857, and Tgm/Anj-858. Tgm/Anj-862 was the most superior genotypes for having the highest number of branches, number of pods, and 100-seeds weight and seed yield and consistent at both locations. The four genotypes, especially Tgm/Anj-862, were potential to be developed in both locations or other locations with similar environmental conditions.Keywords: grain yield, ultisol, yield components

Abstract

Morphology is performance of a genotype that is influenced by environmental and genetic interaction. This research was to study the quantitatively morphological characters of ten CpMMV-resistant soybean promising lines, i.e. UM.4-1, UM.7-2, UM.2-4, UM.7-6, UM.6-2, UM.6-3, UM.3-2, UM.6-1, UM.7-3, UM.3-4 and two superior varieties Gumitir and Wilis. The study was conducted at Indonesian Legume and Tuber Crops Research Institute (ILETRI) from March to June 2015. The observation was done by measuring the quantitative morphological characters such as leaf length, leaf width, leaf petiol length, leaf area, leaf ratio (P/L) and plant height. The data were tested using multivariate analysis. The results of the analysis showed that there were differences on morphological characters of CpMMV-resistant soybean promising lines as well as superior varieties Gumitir and Wilis based on the leaf length, leaf width, leaf petiol length, leaf area, leaf ratio (P/L) and plant height. Hotellings Trace (0.00) was smaller than the significance value (0.05) showing the differences among the groups.Kata Kunci: kedelai, CpMMV, karakter morfologi kuantitatif
