“…The examined varieties had a particular capacity to react to their surroundings. Tall plants are an important genetic resource for feed production (Birhan et al 2020), while short plants have been recognized as a key characteristic for drought tolerance (Seyoum et al 2019).…”

“…The tested varieties had unique abilities to respond to their surroundings. Sorghum of short variety is more stress-tolerant (Birhan et al 2020), whereas sorghum of a relatively tall variety has great potential as animal feed (Seyoum et al 2019). Considering the flowering time as a measure of adaptation to the growing environment in this study, Kawali could adapt to the environment and maintain good growth performance.…”

Abstract. Hasanah NAU, Purwanto E, Harsono P, Samanhudi, Sakya AT. 2023. Morphological responses of six sorghum varieties on cadmium-contaminated soil. Biodiversitas 24: 3903-3915. Six sorghum varieties were planted on cadmium-contaminated soil and characterized from April to July 2020 at a rice field in Balecatur Gamping, Yogyakarta. The objectives of this experiment were to characterize themorphological responses of six sorghum varieties and select a variety with a high biomass and Cd uptake fora potential phytoremediator. This experiment used six sorghum varieties, namely Super-1, Samurai-1, Suri-3, Numbu, Kawali, and Hitam, following completely randomized design procedures with four replications. The observation of morphological and agronomical characteristics focused on ten plants as the sample of each plot. The result showed that there were differences in the morphological and agronomical characteristics among six sorghum varieties. Varieties were assessed in terms of distinctness and grouped based on the time of panicle emergence, plant height, panicle shape, and caryopsis color. There were threeclasses as follows: Class 1, i.e., time of panicle emergence: very early (Super-1, Suri-3, Numbu, and Hitam); plant height: long (Super-1), medium (Suri-3), short (Numbu and Hitam); panicle shape: panicle broader in the upper part (Numbu), symmetrical (Super-1 and Suri-3), pyramidal (Hitam); caryopsis color: white (Super-1), grayish orange (Suri-3 and Hitam), yellowish orange (Numbu). Class 2, time of panicle emergence: early (Samurai-1); plant height: medium (Samurai-1); panicle shape: panicle broader in the lower part (Samurai-1); caryopsis color: yellowish orange (Samurai-1). Class 3, time of panicle emergence: medium (Kawali); plant height: medium (Kawali); panicle shape: panicle broader in the lower part (Kawali); caryopsis color: yellowish white (Kawali). Assessment of agronomical characteristics revealed that fresh plant weight had a significant positive correlation with plant height R1, plant height R5, stem diameter, leaf bladewidth, thousand-grain weight, and stem sugar content. Several varieties, namely Super-1, Samurai-1 and Kawali, were found to have excellent agronomical characteristics to provide a solid varietal basis for selecting varieties as phytoremediators.

“…Beberapa peneliti melaporkan bahwa karakter bobot biji per tanaman pada sorgum memiliki nilai heritabilitas arti luas yang tinggi (Insan et al, 2016;Gebregergs dan Mekbib, 2020). Karakter-karakter yang memiliki nilai heritabilitas arti luas yang tinggi dapat dijadikan pertimbangan dalam menentukan kriteria seleksi karena faktor genetik lebih berpengaruh daripada faktor lingkungan (Birhan et al, 2020).…”

Karakter stay greenness pada sorgum berkaitan dengan kemampuan mempertahankan kehijauan daun dan laju fotosintesis pada kondisi cekaman. Penelitian ini bertujuan untuk memperoleh informasi kendali genetik karakter agronomi, stay greenness serta identifikasi segregan transgresif empat populasi F2 sorgum. Penelitian telah dilaksanakan bulan Februari sampai Mei 2020 di Kebun Percobaan IPB University Leuwikopo, Dramaga, Bogor, dengan ketinggian 250 m di atas permukaan laut (dpl). Bahan genetik yang digunakan adalah populasi Numbu x Samurai 2, Kawali x Pahat, Kawali x B69, Super 2 x PI-150-20-A, dan tujuh genotipe tetuanya. Setiap populasi terdiri atas 300 tanaman F2 dan masing-masing tetua sebanyak 60 tanaman. Pendugaan kendali genetik berdasarkan nilai skewness dan kurtosis. Identifikasi segregan transgresif menggunakan karakter terpilih berdasarkan nilai parameter genetik. Hasil penelitian menunjukkan bahwa karakter bobot biji per tanaman dikendalikan banyak gen aditif pada populasi Numbu x Samurai 2 dan Kawali x Pahat, sedangkan karakter stay greenness pada semua populasi dikendalikan banyak gen aditif. Semua karakter yang diamati memiliki nilai heritabilitas arti luas sedang sampai tinggi. Delapan belas individu dari persilangan Kawali x B69 dan Super 2 x PI-150-20-A diduga sebagai segregan transgresif berdasarkan karakter bobot biji per tanaman dan stay greenness. Segregan yang diperoleh digalurkan dengan menerapkan metode pedigree. Kata kunci: aksi gen, aditif, indeks transgresif, keragaman genetik

“…To this end, it would be highly desirable to design a breeding program that focuses on incorporating a specific set of component traits of drought tolerance. Recently, Birhan et al, (2020) have identified sorghum genotypes that were well suited for specific drought stress adaptation through traditional breeding and research. On the other hand, in the conventional method of breeding, there exist, always, a problem of linkage drag besides their laborious and time taking techniques (Collard and Mackill 2008).…”

Inthisunpredictableclimaticscenario,increasingcropproductivityunderlow water availability is the foremost challenge. The crops are further seriously affected,andtheyieldsaredrasticallyreducedduetoelevatedtemperature, greenhousegases,andhumidityduringthewater stressperiod.Toensure food security in the coming decades, scientists have summoned to increase thehigh-quality foodwiththeseclimaticvagaries. Thoughseveralagronomic and management strategies were proposed to mitigate the water stress, genetic improvementof cropswithimproveddroughttoleranceis the simple, sustainable and affordable option. Nevertheless, identification and molecular understandingoftheappropriatebreedingtraits thatcanalleviatetheimpact of water stress on crop plants are the trickiest part ofthis strategy. Sorghum (Sorghum bicolor L.)is gaining its importance in water stress tolerance plant breeding, as it has several clearly defined drought-tolerant component traits that promote productivity underlow water environments. The genomics and phenomics information generated in S. bicolor would immensely help breeding plants resilientto thechallenges of a water scarcity. This paper describes themolecularmechanismsofdroughttoleranceusing sorghum bicoloras amodel and howthis information canbeextrapolatedto breed better cultivars in other crops.
