Genetic variability of F2 foxtail millet population derived from ICERI-5 and Botok-10 cross

Abstract

Abstract. Sintia M, Ardie SW, Suwarno WB. 2023. Genetic variability of F2 foxtail millet population derived from ICERI-5 and Botok-10 cross. Biodiversitas 24: 3559-3567. Foxtail millet (Setaria italica (L.) P. Beauv.) is a carbohydrate source with good tolerance to abiotic stress. High productivity, short stature, and early flowering time are the breeding targets of this species. This study aimed to obtain genetic variability of F2 foxtail millet population derived from ICERI-5 and Botok-10 crossand to predict selection response based onweighted selection index. This experiment was conducted in Bogor and consisted of 522 F2 individuals and two parental genotypes. The results showed that the F2 population had shorter plant height and earlier flowering time compared to Botok-10, and higher grainweight per plant compared to ICERI-5. Plant height, flowering time, and grainweight per plant showed moderate to high genotypic coefficient of variation with moderate to high broad-sense heritability. Weighted selection index using the three target traits resulted in ten F2 individuals with higher selection index compared to both parents, with individual number I5B10-4-96 having the highest selection index. Selection responses based on a weighted selection index indicate an expected decrease in flowering time and an increase in grain weight per plant in the next generation.

The Genetic Variability of Indonesian Local Foxtail Millet Accession Based on Agro-morphological Traits and Early Salinity Tolerance Evaluation Utilizing SiDREB2-based SNAP Marker

“…Moderate plant height, early heading time, and high productivity are some targeted traits in the foxtail millet breeding program (Sintia et al 2023). Short-statured plants are more advantageous since taller plants might be prone to lodging (Shah et al 2019), while early heading time is preferred so foxtail millet can be cultivated as a catch crop.…”

Genetic Variation of Foxtail Millet (Setaria italica (L.) P. Beauv.) Germplasm From Polewali Mandar West Sulawesi Based On Morphological Characters

“…In Indonesia, foxtail millet is commonly found in mountainous regions and cultivated in some areas, including West of Sulawesi, South of Sulawesi, Buru Island, East Nusa Tenggara, Bangka Belitung, Central of Java, Papua, Bengkulu, South of Sumatra, and West of Java. Mountain farmers value foxtail millet for its nutritional content and health promoting properties, ability to grow under low external input conditions, tolerance to extreme environmental stress, particularly drought, and patience with pests and diseases (Sintia et al 2023). The farmers and local communities in West Sulawesi Indonesia use foxtail millet as an alternative food crop instead of rice in local culture (Ramlah et al 2020); it is used to make pancakes, porridge, and puddings because of its low allergenic and highly digestible properties (Karpagapandi et al 2023); It also known as food for bird even though millet is rich in fiber (Yulita et al 2018).…”
