Abstract

Phenotypic variance derived from banana [Musa paradisiaca) mutant lines of cv. Barangan were carried out in nursery level which were conducted at CRDIRT-Green House, Pasar Jumat, Jakarta. Several phenotypic performances of mutant lines such as leaf and pseudostem, petiole and leaf length, plant height, leaf width were observed. Number of 150 plants, were then divided into 11 groups based on performance of leaf, pseudostem, and petiole length. Results indicated that 26% was showed for normal performance,while 6,7% was showed for abnormal lamina with normal petiole, 11,3% was showed for abnormal lamina and petiole, 28,7% was given for stunted plant, 3,3% with chocking lamina, 1,3% was showed for abnormal petiole, 2,0% with light green leaf and abnormal petiole, 6,0% was given for reddish pseudostem, 0,7% with cigar leaf, 1,3% was showed for discoloration leaf and 2,7% was showed for elongation leaf and abnormal petiole. From the result of this experiment can be concluded that gamma irradiation with dose 15 Gy produced high phenotypic variance of cv. Barangan.

Abstract

The productivity of the rice plant is commonly influenced by both genotype and environmental factors. One common environmental factor that leads to harvest failure is drought, often caused by low rainfall. Therefore, the development of drought-tolerant varieties should be implemented to obtain optimum productivity under an unfavorable environment. One of the canonical approaches for achieving this is genetic manipulation, such as by gamma radiation-induced mutation. This study aimed to determine the drought tolerance and quantitative characteristics of mutant rice varieties generated from gamma radiation. The methodology used was a split-plot design with two factors, including drought as the first factor consisting of three groups namely control, mid-level, and high-level. The second factor was rice genotypes, which consisted of six genotypes comprising PMG 07/PsJ, PMG 08/ PsJ, and PMG 09/ PsJ (mutant varieties), Gajah Mungkur (parental background), Limboto (drought-tolerant), and IR 20 (drought-susceptible). The data were statistically examined using Analysis of Variance (ANOVA) and further analyzed with Duncan’s Multiple Range Test (DMRT) with a significance level of 5%. The results showed that high-level drought significantly affected plant height during both the vegetative and mature stages. Among the mutants, PMG 08/PsJ exhibited better vegetative growth under dry conditions, retaining a relatively higher height. Drought also had a negative impact on the number of tillers and productive tillers. The PMG 08/PsJ mutant had a slightly higher number of tillers under drought cultivations. On the other hand, PMG 09/PsJ was found to have a relatively more filled grain number per panicle. Leaf rolling and dryness index showed similar trends in all varieties, while drought treatments imposed a delay on the flowering and harvesting age. Although the results demonstrated no substantial improvement over the parental lines, the selected mutant lines provided several beneficial agronomical features such as maintenance of plant height, tiller number, and shorter life cycles under severe drought. These characteristics could serve as valuable genetic resources for breeding programs focused on developing drought-resistant rice varieties for challenging environments.

Abstract

Peningkatan jumlah penduduk setiap tahun menuntut adanya peningkatan produksi padi untuk memenuhi kebutuhan pangan. Budidaya padi gogo menjadi upaya yang dapat dilakukan untuk meningkatkan produksi padi di Indonesia dengan mengoptimalkan penggunaan lahan kering. Penelitian ini bertujuan untuk mengidentifikasi daya hasil dan komponen hasil dari 10 galur mutan padi gogo Situgintung. Penelitian dilaksanakan di Kebun Percobaan Pusat Riset Teknologi Proses Radiasi (PRTPR), ORTN-BRIN, Lebak Bulus, Jakarta Selatan pada bulan Januari hingga Agustus 2023. Penelitian ini menggunakan faktor tunggal yaitu genotipe sebagai perlakuan yang disusun dalam rancangan kelompok lengkap teracak dengan 3 ulangan. Uji beda nyata jujur digunakan untuk mengetahui perbedaan antar perlakuan. Hasil penelitian menunjukkan bahwa seluruh galur mutan yang diuji memiliki produktivitas yang sama dibandingkan dengan dua varietas pembanding Limboto dan Situgintung, kecuali galur G107 dan G29 yang lebih tinggi dibandingkan kedua varietas pembanding serta galur G229 juga nyata lebih tinggi dibandingkan dengan varietas Situgintung. Beberapa karakter menunjukkan korelasi positif terhadap produktivitas galur mutan padi gogo, meliputi lebar daun bendera, panjang batang, jumlah anakan produktif, jumlah anakan total, jumlah gabah bernas, persentase gabah bernas, jumlah gabah total, dan kerapatan gabah per malai. Karakter yang berkorelasi negatif terhadap produktivitas adalah persentase gabah hampa. Kata kunci: padi gogo, galur mutan, produktivitas
