A diallel study of flowering and of ear components of yield in Corn Belt maize and their interactions with population density
A diallel study of American Corn Belt maize (Zea mays L.) was conducted at Holland, Virginia in 1981 and 1982. All possible crosses of twelve inbred parents (A619, A632, B73, H60, H93, H96, Mo17, Oh7B, Pa91, Val7, Va.79:419, Va85) were planted in three replications with population density …

Diallel analysis of diplopodia ear rot resistance in maize and an assessment of the genetic variability of Stenocarpella maydis through isozyme analysis
… inoculations prior to flowering, analyzing a diallel cross for DER resistance, and examining the genetic variability of the fungus from isolates collected from the U.S. and the Republic of South Africa. DER developed in maize following inoculations with a spore suspension prior to flowering in …

Diallel analysis of rind puncture and grain yield and their interactions with plant densities for twelve elite inbred lines of maize, Zea mays L
… twelve inbred lines of maize were crossed in a diallel manner to produce the 66 F₁ single cross hybrids. Hybrids were hand planted in single-row plots with three replications at Holland, Virginia on 10 April and 15 and 16 April, 1981 and 1982, respectively. Plots were comprised of four …

Gene action in the inheritance of agronomic traits in intervarietal diallel crosses and relative importance of gene effects for quantitative characters in Zea mays L
… in the inheritance of agronomic traits in a diallel set of eight inbred lines of sweet corn and all possible Fl hybrids, including parents. Data were analyzed by Jinks and Hayman's diallel analysis for plant and ear height, weight with and without husk, shank and ear length, ear and cob …

Genetics of the Arabidopsis Inflorescence Replacement Program
… were chosen and intercrossed in a partial diallel design with the ultimate aim of mapping quantitative trait loci (QTL) in the populations derived from these crosses. Owing to time constraints, a Bay x Sha recombinant inbred (RI) population rather than the diallel progeny was used to map …

Incorporating molecular markers into applied maize breeding
… were made between marker-trait associations in diallel, testcross, and line per se data sets, and also between marker assisted selection (MAS) and conventional early generation testcross selection.

Classification of Inbreds for Their Value in Improving Elite Maize Hybrids
… x I$\sb2$) is important. A non-reciprocal diallel of 4 maize (Zea mays L.) inbreds of Stiff Stalk Synthetic, 5 of Lancaster, and 5 of unrelated origin were evaluated for grain yield, grain dry matter, earliness of flowering, total lodging, and plant and ear height at two locations in 1984 …

Genetic diversity of midwestern oat germplasm
… from four germplasm sources were crossed in a diallel mating design without reciprocals. F(,1) heterosis for grain yield was evaluated in two experiments, and 48 F(,2)-derived lines from each of the 36 matings were evaluated for bundle weight, grain yield, straw yield, harvest index, height, …

Heterosis between semidormant and nondormant derived alfalfa germplasm
… derived populations were hand crossed in a half diallel mating design. A seeded trial was established at one Iowa location in 2003 and transplanted trials grown at two locations at 2004. In spite of the observation of better yield in some of the particular crosses, a general heterotic pattern was …

Identification and genetic characterization of tobacco accessions possessing resistance to tobacco cyst nematode
… and two susceptible lines were selected and a diallel study was conducted to determine the inheritance of resistance to TCN. Additive gene action contributed significantly to inheritance of TCN resistance. Three accessions, 'Burley 64', 'Kutsaga 110', and 'Tl 1597', were determined to be the …

Barley Yellow Dwarf of Winter Wheat: Effects on Germplasm, and Inheritance, Combining Ability, and Reciprocal Effect for Tolerance to the Barley Yellow Dwarf Virus
… and spring times of infection. In a 12-parent diallel mating design which included reciprocal crosses in both F(,1) and F(,2) generations, reciprocal effect accounted for very little of the variability among entries for tolerance to BYDV. General combining ability and specific combining ability …

Agronomic evaluation of four maize synthetics after recurrent selection for yield and evaluation of selected lines from the synthetics
… BSSSCO and BS13(S(,2))C1 were compared using a diallel mating scheme within both groups of lines. Nonadditive genetic variance was greater than additive variance for the BSSSCO lines; however, additive genetic variance was more important for the BS13(S(,2))C1 lines.</p>

Epistasis for agronomic traits in elite maize hybrids
… for all possible hybrids of a five-parent diallel in both the Iowa Stiff Stalk Synthetic (BSSS) heterotic group and the non-BSSS heterotic group. Two testers were hybridized to each of the 10 possible hybrid progeny sets in the BSSS group while two different testers were hybridized to the …

Genetics underlying flaking grit yield from dry milled maize grain
… maize hybrids. The 12 inbreds were crossed in a diallel design without reciprocals to create 66 test hybrids which were evaluated for agronomic, dry milling, ear, and kernel properties over 3 years.
