“…Characters with high heritability values were plant height, leaf angle, length and width of leaf, ear length and diameter, rows kernel number per ear, number of kernels per row, weight of harvested ears, water content, weight of 1000 kernels and yields. The results of this study were in line with the results obtained in the maize experiment on dry land where several characters such plant height, leave number per plant, ear length, ear diameter, weight of dry ear harvested per plant and yield have high heritability values [14,21]. Similar results were reported for ear lenght and plant height [22], number of kernels per row in maize number of kernel row per ear 1000 grain weight [23,24].…”

“…HA = Harvested area (m 2 ), WC = kernel water content at harvest (%), B = Wet ear weight (kg), R= Shelling percentage and Y=Yield (%). Genotypic and phenotypic diversity values were derived from analysis of variance [14], as presented in Table 1. The grouping of heritability values is H2 > 0.5 (high), 0.2 <H2 <0.5 (medium), and H2 <0.2 (low) [15].…”

The selection of hybrid maize plants that adapt to dry land in the medium plains is very important considering the very widely available such land in Indonesia, so the existence of adaptive varieties is needed. Information on agronomic characters of adaptive hybrid maize is the basic information for character selection to make the breeding program more effective. The study aims to determine the genetic variability, heritability, and correlation of hybrid maize agronomic characters tested in dry land of medium plains. The genetic material used 22 maize hybrids, arranged in randomized block design with 3 replications. The experiment was carried out in Polewali Mandar Regency, West Sulawesi from June to September 2021. The results showed the characters that were strongly influenced by the environment were ear position height, stem diameter, male and female flowering time, and shelling percentage. The characters of stem diameter, male and female flowering time, and shelling percentage can be used for selection characters in the advanced generations. The characters that had significantly positively correlated with yield characters were plant height, leaf width, ear diameter, harvested ear weight, and weight of 1000 kernels, while the character that had negatively correlated with yield was kernel moisture content.

“…Additionally, cob length, number of grains per cob, cob diameter, and 100-seed weight have been highlighted as important yield-contributing characters (Gul et al, 2015). Furthermore, harvested dry cobs weight per plant has shown a strong phenotypic correlation with yield, emphasizing its significance as a selection indicator (Sudika et al, 2022).…”

The development of hybrid sweet corn varieties involves the selection of parental lines with specific traits to ensure good yield potential. The selection of inbred lines of sweet corn is a critical aspect of breeding programs aimed at developing improved varieties. This research will provide useful information of sweet corn inbreed lines have the potential to be developed as parent lines in the development of hybrid varieties. The study utilized 24 inbred lines (G1-G24) of sweet corn and employed a Randomized Complete Block Design (RCBD). Data analysis involved the use of analysis of variance with a 5% significance level, path and dendrogram analysis. Based on the analysis of 24 inbreed line of sweet corn, the potential for selecting parents based on quantitative traits influencing the outcome is evident in inbreed line G18, G12, G4, G23, and G20. Identification of these potential parents is essential for the genetic improvement of the population. The correlation heatmap data indicates a 41% correlation between the number of rows and cob stag length, and correlation between number of rows and ear diameter by 48%. The path diagram indicates that fresh weight, a crucial measure of crop yield, is strongly influenced by several agronomic traits, including plant height, ear length, ear diameter, dry weight, number of plants, row length, brix, and ear stalk. G24 can indeed be used as one of the parents with other group in hybrid breeding programs.

“…The lines produced from free-pollinated crosses had high diversity. Genetic variance and diversity of F2 corn plant populations were found (Sudika et al, 2022).The estimates of genetic effects traits were specific in eachgenotypes (Nabila et al, 2022). According to Juita et al (2022), the F2 and F3 lines from free pollination crosses had better characters than their parents, in which 88.11% of the lines had purple seed color.…”

Purple corn is a cereal plant that has health benefits. Purple corn contains anthocyanins, which are useful as anticancer and antioxidants, and has high nutritional value. Improving the quality of corn production can be done through plant breeding. This study aimed to determine the value of variability, heritability and expected genetic advance of F3 purple corn from open-pollinated hybridization. The research was conducted from December 2020 to April 2021 at Universitas Bangka Belitung. The study used a single plant design experimental method. The selection used was ear to row. The results showed that the color of the seeds of the F3 line was dominated by orange. The lines have different quantitative characters. The lines that have the most purple color were F3-PXU-11-25, F3-PXU-6-16, and F3-PXU-11-20. The value of phenotypic variability and genotypic variability of the broad criteria was found in the weight of corn cob with husk and without husk. The broad heritability was high on the weight corn cob with and without husk. The value of the expected genetic advance progress of the high criteria was on the characters of cob length, the weight of 100 seeds, the weight of corn cob with husk, and the weight of corn cob without husk.
