Diallel analysis assumes that the genetic interactions contributing to trait variation can be adequately captured by GCA and SCA effects. However, in reality, more complex, involving higher-order epistatic interactions, pleiotropy, other factors are not accounted for traditional diallel analysis, this purpose, studies were conducted study combinatorial ability of wheat varieties widely planted ...

Traditional rice varieties having high flavonoids and anthocyanin traits were hybridized to high-yielding quality cultivars assess their combining ability. Significant variation was observed among parents hybrids for the studied. The predominance of non-additive gene action single plant yield, total flavonoid content, amylose whereas, trait registered additive in study. genotypes ADT 37 (R) 45 ...

general and specific combining ability of some rice lines and cultivars with irri sources were determined using the line × tester procedure (5 pure lines were crossed with 4 local cultivars as tester). parents and their progenies were planted in a randomized complete block design with three replications in the research field of iran rice research institute. traits such as yield and its componen...

Combining ability of inbred lines is the ultimate factor determining future usefulness for hybrid development while, an idea about nature gene action controlling yield and contributing characters important fruitful breeding programme. Owing to this, present study was carried out investigate General Ability (GCA) Specific (SCA) effect parental hybrids respectively, deduce type regulating grain i...

Early maturity and genotype by environment interaction (GEI) have always been challenging concerns for breeders in selecting appropriate parents breeding programs. The presented study aimed to investigate early the dimension of gene action, as well as, assess performance half-diallel populations using eight advanced sweet corn inbred lines their 28 F1 hybrids with two commercial checks yield-re...

Our objectives were to evaluate general and specific combining ability (SCA) genetic divergence among tropical maize inbred lines using single sequence repeat (SSR) markers. Thirteen crossed based on a complete diallel scheme. Hybrids three checks evaluated in lattice experimental design. Silk anthesis flowering, average plant height, ear white spot (Pantoea ananatis) gray leaf (Cercospora zeae...

The two most important activities in maize breeding are the development of inbred lines with high values general combining ability (GCA) and specific (SCA), identification hybrids yield potentials. Genomic selection (GS) is a promising genomic tool to perform on untested material based estimated from prediction (GP). In this study, GP analyses were carried out estimate performance hybrids, GCA,...

Parent-of-origin effects have long been recognized and exploited in plant breeding genetic studies. These can be conferred by preferential expression of an allele from one parent, organellar effects, or altered organellar-nuclear interaction. The goal this work was to evaluate parent-of-origin on seed, cotyledon, early growth traits cucumber using a full eight-by-eight diallel crossing two doub...
