“…The hybrid L 2 x T 2 (58.03 %) manifested maximum standard heterosis, followed by hybrid L 1 x T 1 (52.35%) . The significant better parent heterosis and standard heterosis for green cob yield were also reported by Lahane et al (2015), Patel et al (2019), Kumari et al (2018), Gami et al (2018) and Chavan et al(2022). None of the hybrids under study recorded significant standard heterosis for cob length.…”

Heterosis is the potential tool to achieve sustainability in crop production. Identifying appropriate parental combinations is a prerequisite for deriving the highest level of heterosis, which is of immense value for commercializing hybrids. In the present experiment, fifty hybrids were generated by crossing ten lines with five testers using line × tester mating design in sweet corn. Fifty hybrids and their respective parents were evaluated along with the standard check sugar 75. Based on per se values, the lines L 1 , L8, L 7 and L 10 and tester T 1 and T 5 were considered superior for green cob yield, while in the case of hybrids, L

“…Maize (Zea mays) is a monocot cereal grain belonging to the family Poaceae and tribe Maydae. Maize is considered the queen of cereals as it possesses the highest genetic yield potential rather than other cereals (Gami et al, 2018). Along with the traditional way of use as food, feed, and fodder, maize can also be used as raw material in a variety of food and business products such as starch, sweeteners, oil, drinks, glue, Industrial alcohol, and gas ethanol.…”

It is very important to study and understand the inter-relationships among the yield and yield attributing traits as well as heritability for the increased efficiency of the breeding programs. Thus, this research is meant to examine economic and biological performance and then measure the correlation between these traits and their heritability. A field experiment was performed in a Randomized Block layout with three replications, every assigned with fifteen treatments in Bharatpur, Chitwan. Effects confirmed considerable variants among all the found quantitative data. Days to tassel initiation were positively and significantly correlated with days to silking (0.83***), days to maturity (0.85**), and days to anthesis (0.87**). Thousand seed weight was significantly and positively correlated with shelling percentage (0.34*). Grain yield was significantly and positively correlated with cob length (0.32*) and number of grains per row (0.33*) whereas highly significant and positively correlated with circumference (0.43***). Traits like days to maturity (0.3), shelling percentage (0.3), and grain yield (0.6) exhibited moderate heritability while others exhibited low heritability. RL-294/CML-226 had the highest grain yield (7.7 t/ha) and grain per row (15.2) with medium performance for other characters. RML-57/RL-174 recorded the highest rows per cob (39.7), cob length (18cm), and shelling percentage (80%) whereas the lowest days to maturity (116.7 DAS) and fluctuating performance in others. Variety RML-86/RML-146 showed better consistent performance for all the traits with the third-highest grain yield (7.1 t/ha) except for shelling percentage (which was the lowest) and days to maturity (which was the longest). This depicts that the two varieties RL-294/CML-226 and RML-86/RML-146 have good possibilities for improvement and cultivation in that area.

The research was carried out with the aim of estimating the general and specific capabilities of the coalition and the genetic action of inbred lines of maize The field experiment was carried out in one of the agricultural fields of Al-Khalidiya District - Anbar Governorate - Iraq for the spring season 2019, five inbred lines AG116, AG-M20, MH17, MH121 and ZM4 were used for this study and entered into a full diallel-cross breeding program, and evaluate the behavior of these inbred lines and their diallel and reciprocal crosses according to the first Griffing method and the fixed model. A comparison experiment was carried out between parental inbred lines and diallel and reciprocal hybrids using the RCBD design in split-plot arrangement with three replications. Where the irrigation intervals 6 and 12 days allocated to the main plots, and genotypes (inbred lines and hybrids) allocated to the sub plots in order to estimate the general and specific combining ability of the studied traits. The results of the study indicated that there were significant differences between the parental inbred lines and their diallel and reciprocal hybrids in the general and specific combining abilities and their effects for most of the studied traits. The inbred ZM4 gave the highest negative combining ability to female flowering, which was −0.77 and −1.06 for 6 and 12-day irrigation intervals, respectively. While the MH121 inbred line with 6-day irrigation interval and ZM4 inbred line with 12-day irrigation interval were distinguished by giving it the highest positive and significant combining ability of grain yield, which amounted to 4.78 and 9.45, respectively. The specific combining ability of the hybrids was characterized by negative and positive values, the cross-hybrid AG116 × AGM20 with the irrigation interval of 6 days gave the highest positive and significant combining ability of 34.05. While the hybrid MH17 × ZM4 with an irrigation interval of 12 days was distinguished by giving it a positive combining ability of 7.12. As for the reciprocal hybrids, the reciprocal hybrid MH121 × AG116 with irrigation intervals of 6 and 12 days gave the highest positive and significant values of 48.74 and 25.76, respectively. The percentage of heritability in the broad sense was 99.8% in the leaf area of the 6-day irrigation interval, while with the 12-day irrigation interval it was 98.76% in the female flowering trait. Whereas, the percentages of heritability in the narrow sense reached 78% in the number of rows in ear with the irrigation interval of 6 days for the reciprocal hybrids, while it reached 78.91 in the reciprocal hybrids at the 12-day irrigation interval for female flowering.
