Abstract

National demand on soybean can be full filled by extending production area including marginal lands. Tidal swamp is one of marginal lands which potentially can be cultivated for soybean production with the use of tolerant varieties to waterlogging. So far, there are only two varieties that are tolerant to tidal swamp condition. This research was conducted to study the response of soybean genotypes to waterlogging and to provide gene resources in breeding for tidal tolerant variety. The research was conducted from October 2007 to February 2008 in the glasshouse of Indonesian Legume and Tuber Crops Research Institute (ILETRI), Malang. The experimental design was split-plot with two replications; where the main plot was waterlogging treatment and the sub plot was soybean genotype (17 genotypes of ILETRI collection). The results showed that soybean genotypes had different responses to different water treatments, shown on the number of branches and reproductive nodes, the number of filled and unfilled pods, and yield (dry seeds) per plant. Waterlogging inhibited plant growth of all traits. Under waterlogging, the highest number of reproductive nodes and fi  lled pods, and yield per plant was from MLGG 0537 i.e. 12.25, 19.25, and 3.13 g plant-1, respectively.   Keywords: germplasms, soybean,  waterlogging

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

Soybean  is a staple commodities agricultural in Indonesia, but the production of soybean in Indonesia is still low due to the attacks of disease caused by infection of CpMMV. This research was conducted to study anatomical characteristics of the 10 soybean  linesto CpMMV and two superior varieties.The research was conducted atJambegede Research Station, Indonesian Legume and Tuber Crops Research Institute, Malang andlaboratory of genetics, State University of Malang  to observe the anatomy of leaf include the length, width, and number of stomata and the length and number of trikoma.The test was analyzed using one-way ANOVA. Results of the analysis showed significance > α (0.05) on each character, this indicates there is no difference in the character of both stomata and trikoma on 10 soybeanslines to CpMMVand two varieties superior.Kata kunci: Anatomi, kedelai, CpMMV

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

Abstract

This study aimed to determine the effect giberelin doses on the morphology of several soybeans strains (UM.4-1, UM.7-2, UM.2-4, UM.7-6, UM.6-2 , Gumitir and Wilis) which have been attacked by Bemisia tabaci. Research was conducted at Research Station, Indonesian Legume and Tuber Crops Research Institute, Malang. The design of the study was a complete split plot randomized block design. Spraying gibberellin on 35 days old (35 HST) after-planting soybean with variation dose of giberellin were 0 ppm, 25 ppm, 50 ppm and 75 ppm. Morphological observation was carried out on leaf length, leaf width, leaf area, ratio of leaf, petiole length, leaf shape, color of hipocotyl, rod coat color, the color of ripe pods and flower color. Data were analyzed using 2 ways Anova. The results  showed that there was a difference in treatment’s effect against leaf width, leaf ratio, leaf area and petiole length of soybeans but no effect of dose variation  on soybean leaf length. There is the effect of the combination treatment (soybean strains and dosage) of the leaf width, leaf ratio, leaf area and petiole  soybeans but there is no effect of combination treatment on soybean leaf length. There is the influence of lines on the leaf width, leaf area and ratio, but there is no influence on the long soybean lines of soybean leaf and petiole).
