Abstract

Cekaman air merupakan salah satu faktor pembatas pertumbuhan dan produksi tanaman termasuk cabai (Capsicum annuum L.). Produktivitas tanaman merupakan karakter yang kompleks sehingga hubungan antarkarakter perlu diketahui untuk mendapatkan kriteria seleksi yang tepat untuk perbaikan tanaman. Penelitian ini bertujuan mengetahui kriteria seleksi terhadap produksi tanaman cabai toleran kekeringan pada fase pembungaan. Penelitian disusun menggunakan Rancangan Acak Lengkap dengan tiga taraf cekaman air, yaitu 100% kapasitas lapang (kontrol), 50% kapasitas lapang (medium stress), dan 25% kapasitas lapang (extreme stress). Hasil analisis korelasi menunjukkan bahwa berbagai karakter yang diamati memperlihatkan perbedaan asosiasi dengan level cekaman kekeringan. Karakter panjang akar tidak dapat digunakan sebagai kriteria seleksi tanaman cabai yang toleran terhadap kekeringan karena panjang akar tidak berkorelasi secara signifikan dengan bobot buah per tanaman pada 50% dan 25% kapasitas lapang. Berdasarkan korelasi dan analisis lintas pada kondisi normal (100% kapasitas lapang) dan kondisi tercekam (50% kapasitas lapang), karakter jumlah buah dan persentase fruit set berkorelasi positif dan berpengaruh langsung terhadap bobot buah per tanaman sehingga dapat digunakan sebagai kriteria seleksi untuk perbaikan tanaman cabai yang toleran kekeringan.KeywordsCekaman air; Cekaman kekeringan; Kriteria seleksi; Cabai; Capsicum annuum LAbstractWater stress is one of limiting factors for plant growth and production, including chili (Capsicum annuum L.). Plant productivity is a complex character so the relationship between characters needs to be known to get the right selection criteria for crop improvement. This study aimed to determine the selection criteria for the production of drought-tolerant chili pepper at the flowering phase. The research arranged under completely randomized design with three levels of water stress, namely 100% water field capacity (control), 50% water field capacity (medium stress) and 25% water field capacity (extreme stress). The results of the correlation analysis showed that the various characters observed exhibited differences associations with drought stress levels. Root length cannot be used for selection criterium of drought tolerant on chili because it was no positive significantly correlated to fruit weight per plant at 50% and 25% water field capacity. Based on correlation and path analysis in normal and drought conditions, the number of fruits and percentage of fruit set can be used as selection criteria for genetic improvement of drought-tolerant on chili plants because these characters were significantly positively correlated and had a direct effect on fruit weight of the plant.

Abstract

Chinese betel is a plant widely found in Indonesia, especially in the ex-Karasidenan area of Surakarta. The existence of growing Chinese betel can be found at various altitudes with humid growing conditions with low sun intensity. People in Surakarta believe that Chinese betel can be used as a traditional medicine. Chinese betel nut is suspected to contain a minerals and bioactive substances that are beneficial to health. Currently, there are few references to Chinese betel, especially related to genetic diversity. This study aims to study the diversity of Chinese betel band patterns based on RAPD markers using OPA-3, OPA-4, OPA-11, OPC-05, and OPD-4 primers. This research was carried out at the Plant Breeding Laboratory, Faculty of Agriculture, Gadjah Mada University, Yogyakarta in July - November 2023 using Chinese betel leaf DNA taken from various places in the ex-karasidenan area of Surakarta. The results of the data analyzed by NTSYSpc version 2.02 with the SimQual (Similarity for Qualitative Data) function using the UPGMA (Unweighted Pair Group with Arithmetic Averaging) method based on the Jaccard similarity index value. The amplification results showed 30 bands with 13 polymorphic bands and 17 monomorphic bands. The level of polymorphism among Chinese betel samples in the five RAPD primers used presented 44.36% of the total 13 polymorphic bands. Jaccard's genetic similarity matrix data ranged from 0.667 – 0.964. The results of the dendogram show that the sample is divided into two clusters with a diversity index of 0.28.

Abstract

Mentik Wangi is one of Indonesia's most popular rice germplasm sources due to its delicate, fluffy texture and arom aroma. Farmers switch to better varieties with high yields due to field challenges in cultivating fragrant rice. The plants are quite tall, harvest time is long, and yield is low; therefore farmers switch to superior varieties with high yields. The purpose of this research was to obtain information on how much yield of 14 mutant rice lines produce and to find mutant lines with short stems and high yields that could be developed to new varieties. The research was conducted at the Tegalgondo Rice Seed Garden Agricultural Land between June to October 2020. This study used a Completely Randomized Block Design (CRBD) with a single factor. Each treatment was repeated three times. The data obtained analyzed with analysis of variance and followed with Duncan Multiple Range Test at 5% level if any significant influences were obtained. The results of this research showed that 14 Mentik Wangi rice lines yields were ranging from 6.70 to  8.21 tons ha-1.Stems from 9 lines with high yields were M6-MW3-G10-14-2, M6-MW3- G12-1-17,  M6-MW3-G5-21-3,  M6-MW3-G5-21-14,  M6-MW3-G6-17-14-4,  M5-MW3-G6-20-9-16,  M6-MW3-G1-1-2  M5-MW3-G1-5-47,  M6-MW3-G6-10-9-26.  These lines were potential candidates for new high-yielding varieties, which would then considered to be evaluated for higher yields or multilocation tests before becoming an official new varieties.Keywords: mentik wangi; mutations; short stem; yield potential;

Abstract

Most farmers determine the cutting of air layer seed in a corp through the amount of the growing roots from air layer itself. The roots can be an indicator of air layer cutting method in a corp. The roots, which are too old or too young, grow less optimal in the air layer seed after being transferred into another cultivated medium. It is necessary to have knowledge about the precise age of air layer cutting so that the vegetative propagation by using air layer can be performed accurately and efficiently. The treatment that is executed is the age of air layer and the corps accession. The result of this research indicates that the effect of the difference air layer age on plant growth is at the age of emerging buds, aged 180 Day is treated with the age of the fastest emerging shoots. The growth of Bojonegoro air layer plants results that does not differ with Wonogiri air layer plants. There is no interaction between air layer age with sapodilla accession on plant growth.
