Abstract Background and aims Cadmium (Cd) contamination is a serious threat to plants humans. Silicon (Si) was reported have some alleviative effects on Cd stress in plants. However, whether Si alleviates toxicity maize genotypes with contrasting root system size are unknown. Methods Effects of application (200 mg kg ?1 soil) shoot growth, uptake transportation under (20 were assessed at the si...

Differences in 3 response among corn (Zea mays L.) genotypes reflect variation in numerous processes involved in N use efficiency. In order to facilitate the study of such variation, we develop and demonstrate a concept for evaluating the contribution of N uptake and utilization processes to variation in N use efficiency. Eight hybrids were grown in a replicated field experiment at two levels o...

Predicting the resistance of hybrids from lines is a relevant approach for accelerating improvement disease in hybrid breeding. In this study, genetic variation and covariation among 76 DH two flint landraces, Kemater (KE) Petkuser (PE), their corresponding testcrosses (TC) were estimated first time material Gibberella ear rot (GER), days to silking (DS), plant height (PHT). Lines TC evaluated ...

The ear leaf veins are an important transport structure in the maize "source" organ; therefore, microscopic phenotypic characteristics and genetic analysis of particularly essential for promoting breeding ideal varieties with high yield quality. In this study, image complete blade cross section was realized using X-ray micro-computed tomography (micro-CT) technology a resolution 13.5 µm. Moreov...

The most comprehensive study was undertaken to investigate genetic variability, character association studies and diversity analysis for yield attributing traits in sixty-five maize genotypes along with five checks raised Augmented block design II observations were recorded on fourteen morphological traits. For all the traits, of variance revealed significant variance. PCV GCV high anthesis sil...

A field experiment was carried out in Al-Hajjaj district- Salah Al-Din Governorate, during the autumn season of 2021. The experimental design randomized complete block (RCBD) three replications. It had ABA concentrations 0, 9 and 12 mg L-1 that sprayed on plants at 4 8 leaves beginning flowering. Results indicated a concentration superior shortening number days from sowing until 50% tasseling (...

Experimental material consisted of 25 lines, 2 testers and their 50 crosses along with standard checks viz., Palam Sankar Makka-2 PSCL 4640 were evaluated using Randomized Block Design two replication during Kharif 2020. Genotype mean square was significant for days to 50% tasseling, silking, 75% brown husk, ear height (cm), plant length circumference kernel rows/cob, kernels/row, 1000-kernel w...
