Sorghum development in Indonesia is directed towards cultivation in dryland and acid soil with low P availability. This research was aimed to obtain information on the performance of sorghum traits for selection in P deficient environment at early vegetative phase (3 weeks after planting), agronomic and yield potential traits in both P sufficient and P deficient environments, also to select high productivity sorghum genotypes which could tolerate P deficiency. The genetic materials used were 19 F7 recombinant inbred lines from a cross of B69 x Numbu developed under optimum condition (indirect breeding) by single seed decent. Variety Numbu and B69 used as checks. This research was conducted at The Indonesian Center for Biotechnology and Agriculture Plant Genetic Resources experimental field, Bogor, from May to September 2017. The experiment used a randomized complete block design with 3 replicates. The results showed that agronomic and yield traits varied among inbred lines under low P condition and optimum P condition. Adaptive lines showed better growth and yield compared to sensitive ones under low P condition. Plant height, panicle weight, and grain weight per panicle had high estimates of broad sense heritability. Selection based on stress tolerance index was able to identify inbred lines 286-6, 115-9, 114-7, 331-8, 170-9, 151-8, 104-7, 413-7, 68-5, 315-6, and 341-7 as tolerant to low P condition.Keywords: heritability, indirect breeding, optimum P condition, stress tolerance index

Development of doubled haploid lines of upland rice through anther culture is one way to obtain superior upland rice varieties tolerant to drought. The objectives of this research were to determine the response of doubled haploid lines to drought stress at seedling stage and to select tolerant doubled haploid lines. The research was conducted at a screenhouse of Muara Research Station, Indonesia Center of Rice Research (ICRR) from November to December 2017. Fourteen doubled haploid lines and 4 check varieties, namely Inpago 10 and Limboto, Salumpikit (drought tolerant check) and IR 20 (drought sensitive check) were used in this study. The experiment was arranged in a randomized complete block design with three replications. The observations were conducted on leaf rolling, leaf drought, and recovery ability. Based on Friedman nonparametric analysis, HR-5-7-1-1 and HR-7-15-2-1 had moderate response with estimated median values for leaf rolling of 3.44 and 3.00, respectively. Three doubled haploid lines namely HR-2-27-2-7, HR-2-34-1-3 and HR-7-15-2-1 had moderate response to drought with estimated median value of leaf drought of 3.56. Nine lines of doubled haploid had tolerant response with estimated median value of recovery ability of 1.00-1.56. Based on weighted selection index, nine doubled haploid lines with positive and high selection index were identified; however, only two lines (HR-7-15-2-1 and B3-2) had selection index higher than Inpago 10 and Limboto.Keywords: drought tolerance, leaf rolling, recovery, weighted selection index

The genetic analysis and selection of transgressive segregants on agronomic characters are required in a sorghumbreeding program for obtaining high proportion homozygosity rapidly in the early generations. This study aimed to obtainthe information on the performance of agronomic characters, estimate genes’ action, broad-sense heritability, coefficient ofgenetic variability, and select transgressive segregant on F2 population of sorghum based on grain yield. The research wasconducted from July 2014 until October 2014 in Dramaga, Bogor. About 300 and 150 individuals F2 populations of B69 ×Numbu and B69 × Kawali, respectively, were used as genetic materials. The results showed that plant height and paniclelength of B69 × Numbu and B69 × Kawali populations were controlled by many genes with additive gene action. The grainyield and grain yield per panicle were controlled by many genes with additive gene action and complementary epistasis,had high heritability, and large coefficients of genetic variability. The transgressive segregant selection had selected 14individuals of B69 × Numbu and 134 individuals of B69 × Kawali populations based on grain yield per panicle.

Plant root has various responses for adaptation under low P condition. This study aims to observe information on root morphology responses from sorghum inbred lines under low P condition. This experiment used a randomized complete block design nested with two factors, namely genotype and P fertilizer dosage. The genotype consisted of 11 sorghum inbred lines (RIL-F8), B-69 (susceptible check), Numbu (tolerant check), and two national varieties (WHP and Kawali). Fertilizer dosage used a dose of sufficient P (66.76 kg ha-1 P2O5) and a dose of low P (33.38 kg ha-1 P2O5). The result showed there were differences in root morphological response between inbred lines (RIL-F8) sorghum under low P conditions. The tolerant lines had a higher character of the longest root length (41.33-61.87 cm), root volume (8.87-12.87 mL), root diameter (0.88-1.02 mm), and proteoid root total (2.4-4.0) as compared to sensitive lines In low P condition. These characters associated with the high biomass of tolerant lines in low P conditions, therefore it could be used as an important character for the selection of root adaptation in low P conditions. Keywords: proteoid root, biomass, phosphorus, tolerant

The impacts of high-temperature stress on rice growth and productivity can be mitigated by growing tolerant varieties. This research was conducted to estimate the genetic parameters and to select the best genotypes based on the susceptibility stress index (SSI) values. This research was conducted from August 2016 to February 2017. Half of the five weeks seedling tiller of each F3 plant was transferred to new pot culture so that each genotype of the F3 rice population grown in two pots. At the maximum vegetative phase, the parental and F3 populations were treated under two different temperatures: in the open ground area and inside a greenhouse with daily mean temperatures of 38.89/22.67 °C dan 41.62/23.32 °C, respectively. The traits observed were yield and yield components. The results showed that the grain yield of the parents and the F3 population were lower when grown inside the greenhouse. The filled grain number per panicle was controlled by additive gene action in these two environments, and is suggested to be a selection character. Selection based on SSI index obtained 13 genotypes tolerant to heat stress and had higher yield compared to their parents. SSD method combined with shuttle breeding is recommended as a breeding method to produce tolerant and high yielding lines. Keywords: heat stress, heritability, segregating population, SSI

Sorgum (Sorghum bicolor (L.) Moench) merupakan tanaman multiguna yang prospektif untuk dikembangkan di Indonesia sebagai sumber pangan, pakan dan bioenergi. Nilai Brix pada nira batang dan karakter malai pada sorgum merupakan karakter hasil yang perlu diperhatikan dalam perakitan varietas sorgum multiguna. Penelitian ini bertujuan untuk memperoleh informasi keragaman nilai Brix pada nira batang dan karakter malai serta komponen hasil dari galur-galur sorgum multiguna IPB dan responnya terhadap perbedaan kondisi lingkungan. Materi genetik yang digunakan adalah 16 galur sorgum generasi F7 hasil seleksi pedigree dan bulk secara terpisah dari tiga populasi hasil persilangan dan 4 varietas sorgum nasional, ditanam menggunakan rancangan acak kelompok di dua kondisi lingkungan yaitu musim kemarau tahun 2019 dan musim hujan tahun 2020. Hasil penelitian menunjukkan karakter hasil yaitu bobot biji per malai dan nilai Brix pada nira batang selain dipengaruhi oleh genotipe dan lingkungan, juga dipengaruhi oleh interaksi genotipe x lingkungan. Analisis korelasi menunjukkan tidak ada hubungan yang signifikan antara nilai Brix pada nira batang dengan bobot biji per malai. Masing-masing berkorelasi nyata positif dengan tinggi tanaman, sehingga sorgum yang tinggi cenderung menghasilkan bobot biji per malai dan nilai Brix yang tinggi. Genotipe PI 150/N-043-16-5-5-P dan PI 150/K-19-6-2-B merupakan genotipe dengan tinggi tanaman, bobot biji per malai dan nilai Brix yang tinggi dibanding genotipe lainnya, dan setara dengan varietas Bioguma 1, Bioguma 3, dan Numbu. Kata kunci: bioenergi, bobot biji per malai, nilai Brix, pakan, pangan
