“…Several investigators reported high heterosis for the yield of maize, i.e. (Alamnie et al, 2006;EL-Badawy et al, 2010;El-Hosary et al, 2006;Hefny, 2007;Kanta et al, 2005;Shafey et al, 2003;Singh et al, 2004). The observations were correlation values between the predicted genotypic values and the observed means of 0.55 to 0.70 and 0.61 to 0.70 for SCA values, with relationship coefficients obtained from microsatellite molecular markers, increasing the technique precision (Balestre et al, 2010).…”

The present study was conducted to evaluate the genetic architecture of five diverse maize genotypes using combining ability analyses. General combining ability (GCA) mean squares were non-significant for grain yield and its related components. Specific combining ability (SCA) mean squares were highly significant for grain yield, the number of grains per row and cob girth while non-significant for days to tasseling, days to silking, plant height, cob height and cob length. These studies suggested the preponderance of non-additive type of gene action for grain yield, cob girth and number of grains per row and additive gene action for days to tasseling, days to silking, plant height, cob height and cob length. The genotypes MIL2020-51 and MIL2020-52 were good general combiners for grain yield, grains per row, cob height and plant height. These lines were the poorest general combiner for days to 50% tasseling and days to 50% silking which suggested that these genotypes had sufficient genes for inducing earliness. The crosses MIL2020-51 x MIL2020-54, MIL2020-52 x MIL2020-53, MIL2020-51 x MIL2020-55, MIL2020-53 x MIL2020-55and MIL2020-52 x MIL2020-55 were the best performing combinations for grain yield. These crosses involved good x good and good x poor general combiners. The reciprocal cross combinations MIL2020-55 x MIL2020-53, MIL2020-52 x MIL20220-51, MIL2020-54I x MIL2020-52, MIL2020-55 x MIL2020-51, MIL2020-54 x MIL2020-51and MIL2020-55 x MIL2020-54 showed large positive estimates for grain yield suggesting that cytoplasmic inheritance also had a role in the expression of grain yield. SCA variances were higher than GCA variances for grain yield, plant height, cob height, number of grains per row, cob girth and cob length which highlighted major role of non-additive genes in the inheritance of these traits. Additive gene action was found more important for number of days to 50% tasseling and number of days to 50% silking

“…Among these bands, 84 bands were polymorphic, and 14 marker loci was revealed (Habiba et al, 2020). In the study which was conducted by Abdein et al (2018), 63 bands were produced while using seven SCoT primers, among them, 38 (60.3%) bands were polymorphic between eight tomato genotypes. At the same time, they used six ISSR primers, 55 bands were amplified with 26 polymorphic bands.…”

“…To date, several durable and effective molecular markers have been produced. DNA-based molecular markers have been developed and used to study genetic diversity in plants, however, only a limited level of polymorphism in tomato plant has been identified (Abdein et al, 2018). Moreover, the evolution of molecular markers, such as amplified fragment length polymorphism (AFLP), restriction fragment length polymorphism (RFLP), randomly amplified polymorphic DNA (RAPD), single nucleotide polymorphism (SNP), simple sequence repeats (SSR), and sequence-related amplified polymorphism (SRAP) allow for greater precision in evaluating the genetic variation of tomato germplasm (García-Martínez et al, 2006;Mata-Nicolás et al, 2020;Caramante et al, 2021;El-Mansy et al, 2021).…”

“…Initiating a trend away from random DNA markers called inter simple sequence repeat (ISSR) (García-Martínez et al, 2006) towards gene-targeted markers, a novel marker system, such as conserved DNA-derived polymorphism (CDDP) and start codon targeted polymorphism (SCoT) (Collard and Mackill 2009a;Abdeldym et al, 2020), which were developed based on the conserved regions within genes. These markers were widely used for variation analysis among tomato accessions (Sharifova et al, 2017;Abdein et al, 2018;Kiani et al, 2018). The analysis of genetic diversity based on both fruit features and molecular markers (i.e., CDDP, SCoT, and ISSR) is noteworthy for tomato breeding and production in order to acquire highquality data.…”

Phenotypic and genotypic characters a source of superior character in the framework of plant breeding programs, especially in increasing local food yields and productivity. In this study, local cultivars of garlic from Eban, North Central Timor (TTU) were used. A total of 15 phenotypic characters were observed, and threeISSR primers were used to identify the phenotypic and genotypic characters. The phenotype characterization showed the similarities in most of the characters observed. The tuber characters showed some differences in tuber diameter (2.5 cm and 1.9 cm), the number of cloves (14 and 10 cloves), tuber weight (11.28 g and 5.18 g), weight of cloves (0.89 g and 0.45 g) for local garlic from Saenam and Fatuneno, respectively. A total of ninepolymorphic bands and 17 monomorphic bands from threeprimers Inter Simple Sequence Repeat (ISSR) were detected. The coefficient of similarity of two groups based on genotypic characters was 0.65% -1%. This study concluded that the two local Eban garlic varieties were different based on morphology and ISSR data. However, phenotypically there were differences in the size of the tubers and cloves, the number of cloves per tuber, and the weight of the cloves.
