“…Moderate heritability was observed in anthesis-silking interval, ear length, number of kernel row −1 , number of cobs plant −1 , no of kernel rows cob −1 (Table 3) . The findings were in agreement with; [ 51 , 52 ] for no of kernels row −1 ; [ 51 ] for no of kernel rows cob −1 ; [ 51 ] for number of cobs plant −1 ; [ 53 ] ear length, anthesis-silking interval was in agreement with reference [ 41 ] findings. Low heritability was observed in ear weight, ear aspect, and cob diameter (Table 3) .…”

“…The higher values of heritability of aforementioned traits could be considered for selection that corroborates the findings of Matin et al [17], Ali et al [21] and Moulin et al [22]. Hb was recorded higher in EH and Yld in the study of Al-Amin et al [18]. The highest GA was reported in TSW (59.31) followed by PH (29.74), EH (26.55).…”

“…The highest GAPM observed in EH (24.23), Yld (23.13), ASI (23.16), TSW (14.99) and PH (14.28) but the lowest in DM (0.80) that was followed by DS (0.92). Al-Amin et al [18] observed higher GAPM in CD & PH. According to Panse [23] the characters having high Hb value coupling with high GA was due to additive gene effects that was observed in TSW, PH, EH.…”

“…High genotypic coefficient of variation (GCV) were obtained for ASI (17.26), Yld (15.17), EH(13.80) and TSW (9.43). Al-Amin et al [18] observed high GCV in PH, CD and Yld/plant. The characters with high GCV indicated high potential for selection.…”

“…Positive correlation coefficient with yield was recorded with CD and EH in the study of Matin et al[17], Nataraj et al[25], Ojo et al[26] and Batool et al[27]. Positive correlation with yield also estimated in the studies of Al-Amin et al[18], Bello et al[28] and Sadek et al[29]. PH and EH had positive correlation with yield in the study of Bankole et al[30].…”

The goal of the current investigation was to determine correlation coefficient, path analysis and genetic variability among twenty four maize hybrids for ten characters in a Randomized Block Design (RBD) with three replications at the research field of Plant Breeding Division, Regional Agricultural Research Station, Barisal, Bangladesh Agricultural Research Institute (BARI), Bangladesh during rabi season of 2014-15. The measured traits were Days to 50% tasseling (DT), days to 50% silking (DS), anthesis silking interval (ASI), plant height (PH), ear height (EH), days to maturity (DM), cob length (CL), cob diameter (CD), thousand seed weight (TSW) and yield(yield t/ha). Here yield was considered as dependent variable and the rest of the parameters were independent variable. The data were submitted to analysis of variance and mean values were compared by DMRT test at both 5% and 1% of probability. Positive and significant genotypic, phenotypic correlation coefficient were recorded for yield with cob diameter (rg=0.75**, rp=0.61**), cob length (rg=0.66**and rp=0.42**), plant height (rg=0.62**and rp=0.55**), ear height (rg=0.66**and rp=0.55**) and thousand seed weight (rg=0.36**and rp=0.44**). High genotypic coefficient of variation (GCV) was obtained from anthesis silking interval (17.26), yield (15.17), ear height (13.80) and thousand seed weight (9.43). The highest phenotypic coefficient of variation (PCV) were observed in anthesis silking interval (26.49) followed by yield (20.51), ear height (16.19) and the lowest in days to maturity (0.70). The difference between GCV and PCV of yield indicated that the characters had some environmental influence. The highest heritability was observed for plant height (73.78) followed by ear height (72.67), thousand seed weight (59.52) and days to maturity (55.97) but the lowest heritability identified for days to silking (18.98). The characters with higher values of GCV and heritability of the aforementioned traits were indicative for selection. The plant height had the highest positive direct effect (1.34) on yield followed by days to silking (0.75), cob diameter CD (0.46) and thousand seed weight (0.41), days to maturity (0.21) and cob length (0.20) indicating the effectiveness of direct selection. Direct negative effect on yield was shown by ear height (-1.03), days to tasseling (-0.52) and anthesis silking interval (-0.50) was indicating the effectiveness of indirect selection.

In order to study the effect of plant density on the genetic behavior of the growth and yield of ten genotypes of different origins of yellow corn, this study was conducted during the spring growing season / 2022, in two different locations. The first site is (Mosul site) in the field of agricultural research / College of Agriculture and Forestry / the tourist forest area. The second site is (Bashiqa site) in one of the private agricultural fields of Bashiqa district within the randomized complete block design (R.C.B.D.) with three replications. The results of the genetic environmental aggregate variance analysis of the two study sites indicate that the mean squares of the environments and genotypes were significant for all studied traits at the probability level of 1%. While the overlap of genotypes × environments was significant at a level of probability of 5% for the dates of male and female flowering and plant height, and at a level of probability of 1% for the rest of the other traits except for the number of pips per plant, in which the differences did not reach the limit of significance. Plants cultivated in environment 3 were characterized by the highest grain yield per single plant amounting to 598.940 gm, compared to the highest total grain yield amounting to 31.466 tons.ha−1 of plants grown under environment conditions 1. The broad sense heritability values were high for both male and female flowering dates 0.624 and 0.644. respectively. The expected genetic i advance as a percentage of the average trait was an average value for the traits of total ear weight, number of grains per ear, individual plant grain yield, and total grain yield.
