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

Karakter morfo-agronomik terdiri dari dua jenis yaitu karakter kualitatif dan kuantitatif. karakter kualitatif bersifat diskret dan berupa data skore sedangkan kuantitatif bersifat kontinyu dan terukur. Analisis kekerabatan penting bagi pemulia untuk mengetahui jarak genetik antar genotype dan untuk menentukan tetua persilangan. Diduga terdapat perbedaan hasil analisis kekerabatan genetik berdasarkan data karakter kualitatif dengan kuantitatif. Penelitian ini bertujuan untuk mengetahui perbandingan hasil analisis kekerabatan berdasarkan informasi data kualitatif dan kuantitatif hasil karakterisasi fenotipik padi lokal. Sebanyak 43 padi lokal Jawa Barat digunakan pada kegiatan karakterisasi fenotipik. Karakter kualitatif yang diamati sebanyak 24 karakter dan kuantitatif sebanyak 23 karakter. Karakter-karakter tersebut merupakan hasil karakterisasi MT 2 2014 di Kebun Percobaan Sukamandi-BB Padi. Analisis data menggunakan Minitab versi 14. Hasil penelitian menunjukkan bahwa hasil analisis kekerabatan dengan menggunakan data kualitatif, kuantitatif maupun kombinasi keduanya tidak berbeda nyata pada komponen analisis jumlah Kluster dan level kesamaan. Perbedaan nyata terdapat pada level jarak genetik. Pola distribusi anggota Kluster pada hasil analisis dendogram berdasarkan data karakter kualitatif berbeda dengan hasil analisis dendogram berdasarkan data karakter kuantitatif dan kombinasi. Analisis kekerabatan antar genotipe direkomendasikan menggunakan data kombinasi dari karakter kualitatif dan kuantitatif agar informasi jarak genetik antar genotype lebih valid.

Abstract

More than 80 high yielding varieties of rice have been released nationally by IAARD to support acceleration of national rice production. Inpari 13 was the one of some new variety that has been released at 2011 and have superior trait i.e early maturity and high yielding. Inpari 13 and some another new variety would disseminated at ICM program at this year. That variety needed to evaluated on Display Area and cultivated by using ICM technology and its compared with old variety as well as Ciherang. This study was to evaluate performance and yield of some new varieties compared old varieties specifically in Dem area. The experiment was conducted in West Java AIAT Dem Area, District Jayakerta, Karawang. The study was done on DS 2011 (Mei 2011-Januari 2012) by using randomized block design with 3 replications. Six varieties were tested i.e Ciherang, St. Bagendit, Inpari Inpari-7, Inpari-10, Silugunggo and Inpari-13. Integrated Crop Manajemen system i.e legowo 2:1, optimal fertilization, and IPM were used at this research. The results showed that there were signifant differences between varieties in all characters except leaf color index. Ciherang has the highest plant height (97,59 cm). Inpari-7 has the highest number of productive tillers and 100 grains weight (25 tillers/clump and 2,8 grams) and the least number of empty grains (7 grains/ panicle). St. Bagendit has the highest number of pithy grain (183 grains/panicle). Silugonggo was the early maturity but it’s resistant to stems brown planthopper (almost had a crop failure). The highest dry grain harvest was owned by Situ Bagendit (8,10 t.ha 1) followed Ciherang (8,08 t.ha-1), Inpari-13 (8,07 t.ha-1), Inpari-7 (7,52 t.ha-1), Inpari-10 (6,71 t.ha-1), and Silugonggo (2,05 t.ha-1).

Abstract

The condition of rice field without any irrigation is one of the problems in the rainfed land. This rice field only relies on the existence of water during the rainy day. This causes the limitation of water availability which affect plant growth. This study aimed to know the performance of the rice advance lines, estimated the value of genetic parameters and obtains the best line on drought condition. As many as 100 advance lines (> F8) for drought tolerant were tested using Augmented Design in five blocks. A total of six-check varieties were included in the experiment. The research was conducted at Dry Season of 2015 in ICRR-Sukamandi Experimental Field. The result showed that on the drought condition gained the average value for plant height as 103,44 cm, number of productive tillers as 12 tillers, percentage of filling pine grains reached 60,46%, leaf color index as 39,37, and weight of 1.000 grains averaged as 26,34 g, while weight grain per 5 clumps as 166,34 g. Yield trait was converted to hectares as 3,77 t ha-1 in drought conidition. Almost all characters had wide variability, high heritability values and high percentage of expected genetic advance except the number of filling grains per panicle trait. Lines BP17572c-SBY-1-CRB-2-SKI-1-3-PWK-2, ZX115-SKI-0-IND-2-SKI-1-PWK-2, BP30104e, BP17572c-SBY-1-CRB-2 -SKI-1-4-PWK-2, and BP17554-1c-SBY-1-CRB-8-SKI-1-6-PWK-2 provided the best performance with higher yield potential than the best check i.e. Inpari 13. There are ten promising lines which can be continued to the preliminary test for the assembly of rainfed rice varieties

Abstract

In addition to carbohydrates, rice contains other minerals that function to growth and development of vital human organs. On the other hand, the content is influenced by genetic and milling processes. Indonesian Centre of Rice Research (ICRR) has genetic collection resistant to strains of the brown plant hopper (BPH). Genotypes were studied to assemble the pest-resistant varieties with high iron (Fe) and zinc (Zn) content. This study aims to determine the BPH-resistant lines that had high and stable Fe and or  Zn content. The study was conducted in XRF Laboratory, ICRR Sukamandi, West Java in 2015. Fe and Zn were determined by using XRF machine with a system of performance-based X-ray. Total 20 rice lines that resistant to BPH was used Fe and Zn content on brown and polished rice were evaluated duplo. The results showed that milling generally decreased the content of Fe and Zn at rate 56.31% and 20.54%, respectively. The highest Fe content was found in BP19564b-WBC-1-1-4-3 (12.25 ppm), while the highest Zn content in BP19564b-WBC-1-9-8-3 (26.35 ppm). Genotype BP19564b-WBC-1-9-4-2 and BP19564b-WBC-1-9-8-3 exhibited the lowest in reduction Fe and Zn content, respective, from brown to polished rice.

Abstract

Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is the major disease in rice plants causing considerable economic losses. The objective of the study was to evaluate the resistant International Rice Bacterial Blight (IRBB) lines against bacterial leaf blight and the identification of Xoo pathotype from Central Java Province as the basis recommendation of the resistant varieties assembly with the background of resistant genes to overcome BLB disease. The evaluation of Xoo isolates from 22 districts in Central Java Province on IRBB lines was conducted in the rainy season 2016-2017 using split plot with three replications. The main plot was 15 IRBB lines, while the subplot was 110 Xoo isolates. Among 15 lines of IRBB, there were 10 lines have functioned as pathotype examiner of Xoo. The results obtained 6 lines were reacted resistant, namely IRBB5, IRBB7, IRBB8, IRBB57, IRBB64, and IRBB66. The IRBB66 line can be used as a resistant elder for the assembly of BLB resistant varieties because it has a combination of pyramiding resistant genes that were effective against BLB in some areas of Central Java Province. Pathotype IX was only found and dominant in Pemalang. Pathotype X was obtained in six districts of Tegal, Brebes, Banjarnegara, Purbalingga, Purworejo, and Grobogan. Pathotype XII was the most dominant prototype in 15 districts. Assembling of resistant varieties with resistant gene backgrounds based on the existence of a specific Xoo pathotype in the field can reduce the severity of BLB disease.
