Judul: Analisis Lintas Beberapa Karakter Agronomi untuk Pengembangan Kriteria Seleksi Tanaman Sorgum (Sorghum bicolor L. Moench)
Abstrak: Almost all parts of cereal sorghum plants can be used, so that sorghum needs to be cultivated and improved quality. Sorghum quality improvement can be done through plant breeding. One of the agronomic characters that need to be improved agronomic quality is yield plants. Sorghum yield was also be affected by other agronomic characters. The great effect on the agronomic characters crop yield can be determined by path analysis and levels of inheritance properties can be determined based on the value of heritability. Agronomic characters under study is the production of dry seeds, total biomass production, biomass production without seeds, 50% flowering, panicle length, plant height, maturity, weight of 1000 seeds, panicle weight, stem diameter, and number of stem segments. The results of this study indicate that yield based on the production of dry seeds (PBK) and total biomass production (PBS) was the most dominant effect of the increase in panicle weight (BM) so BM can be used as selection criteria sorghum plants with moderate levels of heritability. In addition, panicle length (PM) can also be used as selection criteria sorghum because PBS was the most dominant effect of the increase in PM with a high degree of heritability. Yield based on biomass production without seeds (PBTB) was not affected by other agronomic characters.

Judul: Variability of Panicle Morphological Characters and Yield of  Sorghum (Sorghum bicolor (L.) Moench) in the F4 Generation.
Abstrak: Sorgum merupakan tanaman pangan penting kelima di dunia. Morfologis malai diduga mempengaruhi hasil sehingga dilakukan upaya untuk meningkatkan produktivitas dengan persilangan. Penelitian bertujuan menginfomasikan keragaman karakter malai dan hasil sorgum populasi F4 serta mengidentifikasi genotipe yang berpotensi hasil lebih baik dari tetua, dilaksanakan pada bulan Februari-Juli 2021 di Kebun Percobaan leuwikopo dan Laboratorium Pemuliaan Tanaman IPB. Rancangan yang digunakan adalah rancangan augmented- RKLT faktor tunggal berupa genotipe terdiri 40 genotipe uji hasil persilangan Kawali-Pahat dan 5 genotipe pembanding diulang 4 kali. Hasil analisis ragam menunjukkan genotipe berpengaruh nyata terhadap beberapa karakter. Genotipe 4, 32, 56, 57, 66, 67, 120, 126, 129, 133 dan 140 berpotensi untuk dikembangkan karena memiliki keragaan karakter agronomi, komponen hasil dan morfologi malai yang unggul. Karakter tinggi tanaman, lebar daun, bobot biomassa basah dan bobot 1000 butir dapat dijadikan sebagai karakter seleksi karena memiliki nilai heritabilitas yang tinggi dan koefisien keragaman genetik yang sedang sampai luas., Sorghum is the fifth most important food crop in the world. Morphology of panicle can be correlated to grain yield. Efforts have been made to increase productivity hybridization. The study aimed to obtain information on the genetic variabilty of panicle character and yield of sorghum in the F4 population and also identify genotypes that have better yield potential than parents. The experiment was conducted at Leuwikopo Experimental Farm and plant breeding laboratory IPB from February to July 2021. The experimental design used is Augmented Design-RCBD one factor, this genotype consists 40 genotypes of sorghum F4 from crosses Kawali-Pahat and 5 comparison varieties in 4 replications. The results of variance analysis showed that genotype had a significant effect on several characters. Genotype number 4, 32, 56, 57, 66, 67, 120, 126, 129, 133 and 140 have the potential to be developed into varieties because of superior performance of agronomic characters, yield components, and the morphology of panicle characters. Characters of plant height, width leaf, stover weight and weight of 1000 seed can be used as selection characters because of high heritability value and moderate to broad genetic variability coefficient.
