Partial diallel crossing designs are in common use among evolutionary geneticists, as well as among plant and animal breeders. When the goal is to make statements about populations represented by a given set of lines, it is desirable to maximize the number of lines sampled given a set number of crosses among them. We propose an augmented round-robin design that accomplishes this. We develop a h...

Six parent diallel cross without reciprocal was studied to investigate the genetic behavior of different agronomic traits in rice. The analysis of Wr-Vr graph showed that panicle length, thousand grain weight and grain yield per plant did not follow the additivedominance model indicating epistatic gene action responsible for the expression of these traits. All other traits under the study were ...

A partial diallel design was used among 20 maize inbred lines to form 110 F1 hybrids to generate information on the values of these lines for developing insect resistant maize varieties during the short rains season of 2006. The hybrids were evaluated for resistance to the C. partellus and B. fusca, and for agronomic performance over two seasons during long and short rains of 2007 at a mid-alti...

Abstract: In many agricultural crops, the number of parents used in cross breeding make it difficult to obtain all possible hybrids diallels. Therefore, using maize as a model plant and based on traits with high low heritabilities, aim present study was quantify correlation estimates general combining ability (GCA) specific (SCA) between complete diallel circulant diallel, without inclusion par...

Increasing drought incidence and infertile soils require the improvement of maize for nitrogen use efficiency (NUE) under conditions. The objectives were to assess tolerance genetic effects Algerian populations no-nitrogen water stress. We evaluated a diallel among six vs. 120 kg/ha N fertilization control. Variability was significant their crosses NUE drought. Additive could be capitalized usi...

Abstract The objective of this work was to investigate the genetic control black bean (Phaseolus vulgaris) and select parents segregating populations with high resistance Fusarium wilt, yield, greater 100-seed weight (100SW), using a partial diallel cross. Twenty-five were obtained from two groups – first five resistant second susceptible wilt. evaluated in experiments three years/generations f...

to assess heritability, gene action and combining ability of rice varieties for characteristics related to grain appearance and cooking quality, the progenies derived from direct and reverse crosses of the 6×6 complete diallel together with their parents included hashemi, hassani, shahpasand, kadous, vandana and ir36 were grown in a randomized complete block design with three replications in th...

With the aim of estimating genetic parameters and identifying superior popcorn combinations, 10 parents were crossed in a circulant diallel and evaluated together with the 15 resulting hybrids at two locations in two growing seasons for grain yield, number of broken plants, number of partially husked ears and popping expansion. The hybrids were less sensitive to environmental variations than th...
