“…Biomass yield and yield components were inversely correlated with days to tasseling (r = -0.33 to -0.50 for Cross 1, r = -0.23 to -0.43 for Cross 2) and days to silking (r = -0.38 to -0.63 for Cross 1, r = -0.24 to -0.53 for Cross 2) in both populations, which implied that earlier maturing individuals had lower biomass yield. Similar results were reported by Kashiani et al (2014) and Saleh et al (2002). The results on the genetic correlations amongst biomass yield its components were consistent with those of the phenotypic correlations such that the correlation coefficients were high and significant (at p<0.01), suggesting that all biomass yield traits (fresh and dry plant yield) and their components were genetically correlated.…”

“…Both heritability and genetic advance estimates could give a suggestion on the genetic control of traits (Anshuman et al 2013;Bekele & Rao 2014;Kumar et al 2014). For instance, traits like days to tasseling and silking have high heritability and low GCV and PCV, suggesting that the observed variation in these traits were attributed to a small number of genes with dominance effects (Saleh et al 2002). This was in accordance with the findings of and Saleh et al (2002) in their studies of heritability for yield traits in sweet corn and Ravindra and Karan (2018) for grain corn.…”

“…Many studies showed strong correlation among related traits. Positive correlations were reported for yield and yield related components namely ear yield, grain yield, biomass yield, plant height, number of leaves per plant, stem girth and leaf to stem ratio (Bekele & Rao 2014;Kapoor 2017;Saleh et al 2002;Umakanth et al 2000). The same correlation patterns were also found among the cell wall components, namely the neutral and acid detergent fibre contents (Cardinal et al 2003).…”

Two F2 populations segregating for biomass yield and forage quality traits were developed from two separate crosses of tropically adapted maize inbred lines. The parental, F1 and F2 generations of both crosses were evaluated to estimate broad sense heritability, genetic advance and correlations for these traits to suggest the best traits as selection criteria towards breeding forage maize with high yield and quality.In Cross 1, biomass yield trait with the highest broad-sense heritability was plant height (70.03%), whereas forage quality trait with the highest heritability estimate was crude protein content (66.60%). Heritability estimates in Cross 2 were high for all biomass yield traits and forage quality traits (>50% for all traits). Indigestible cell wall component represented by acid detergent lignin content was found to be highly heritable in both populations. High genetic advance as percent of mean were found for fresh and dry plant yield as well as for lignin content in both populations. Correlation analysis on all traits showed that all biomass yield components were significantly correlated. All traits related to cell wall content were positively correlated and acid detergent lignin was positively correlated with dry plant yield. Traits with high to moderate heritability and high predicted genetic advance, namely plant height, fresh plant yield and protein content can be used as selection criteria to improve maize biomass yield and nutritive quality for forage utilization. Selecting for higher biomass yield would also result in selecting individuals with higher lignin content as shown by the correlation analysis.

“…In this study, Jagung Manis Sandakan (C5) showed the longest (16.24 cm), and Jagung Kampung Telupid (C2) recorded the shortest (7 cm) cob length (Figure 6). A significant difference in cob length among different corn varieties was mentioned by previous studies, which ranges between 11.9 to 17 cm [28], an average of 12.5 cm [29] and 13.09 to 14.27 cm [30]. Variety significantly influences plant height, cob length, and cob weight [16].…”

Environmentally friendly soil amendments are becoming increasingly popular currently. This experiment was conducted in the insect-proof rain shelter from 15th August until 1st December 2020. This study compares the growth and yield of five local corn cultivars collected in Sabah; Jagung Kuning Ranau, Jagung Kampung Telupid, Jagung Pulut Telupid, Jagung Manis Telupid, and Jagung Manis Sandakan, planted on the same planting medium consisting of 25% dairy farm effluent (DFE) compost and 75% Silabukan soil. The experiment was laid in a Completely Randomized Design (CRD) with five replications. Corn cultivars had a significant influence (p<0.05) on all growth and yield parameters except for flag leaf width and the number of cobs per plant. Jagung Manis Telupid (C4) outperformed other cultivars in plant height (296.5 cm) and the number of leaves per plant (13.75). The highest flag leaf length (67.67 cm) was recorded by Jagung Kampung Telupid (C2). In comparison, Jagung Manis Sandakan (C5) had the highest cob length (16.24 cm), cob diameter (38 mm) and cob weight (106.63 g). Therefore, planting Jagung Manis Telupid (C4) is highly recommended for silage purposes, while Jagung Manis Sandakan (C5) for its cob yields. Further study in the open field is suggested as the growth and yield performance might be different due to other variables.

“…reported that the effect of selection can depend also on the performance level of the initial population. As our initial population was selected for several years by mass selection, the additive variance for traits with high heritability might have been exploited already well and further improvement would be only possible by selection under environments with greater diversity.4.2 | Effect on earliness of full-sib selectionMaize-flowering time is a highly heritable trait(Hemavathy, 2020;Ojo et al, 2020;Saboor Khan et al, 2018;G.

Sweet corn breeding goals differ from grain or silage corn. Sweet corn goals focus on marketable yield including several quality traits. This study explores the effect of a single cycle of full‐sib selection and S2 selection on improving the marketable yield of an open‐pollinated sweet corn population. The selected populations were subsequently compared in four environments for several plant‐, yield‐ and quality traits relative to the original population. Analysis of variance was used to detect selection progress and indirect effects of selection. Full‐sib and S2‐selection decreased total yield. Marketable yield was decreased more by S2‐selection than by full‐sib selection. Flowering time was changed by full‐sib selection, but not by S2‐selection. Full‐sib selection improved ear quality by increasing ear length, the diameter of the ear and the number of kernel rows. S2‐selection showed no effect or a negative effect on ear quality. The application of a single cycle of selection using either method seemed inadequate for increasing marketable yield. More cycles might be necessary to make significant improvements.
