“…The crosses (ICSA608 × ICSR29) and (ICSA52 × ICSR89028) gave maximum SCA effects of 12.06 and 11.74, respectively, which may be considered suitable for hybrid crop development (Table 7). These findings are in agreement with those obtained by Hovny & El-Dsouky (2007), Abdel-Mottaleb (2009), Essa (2009), Mahdy et al (2011 and Amir & Mohamed (2015).

“…They found that the relative hybrid mean superiority over the mid parent values was highest for grain yield followed by plant height and above ground dry matter. Our findings are in accordance with the findings of Hovny & El-Dsouky (2007), AbdelMottaleb (2009), Essa (2009), Mahdy et al (2011), Omar et al (2014 and Amir & Mohamed (2015).…”

“…For SCA, effects, the crosses ICSA613 × ICSR89028 and ICSA20 × ICSR53 gave positive and highly significant SCA effects indicating that these crosses can be considered desirable combiners. This is in agreement with the findings of Hovny & El-Dsouky (2007), Abdel-Mottaleb (2009), Essa (2009), Mahdy et al (2011), Omar et al (2014 and Amir & Mohamed (2015).…”

“…The results obtained were concur with those obtained by Al-Nagar et al (2007) and Abou-Amer & Kewan (2014) who found that N and NP levels and their interaction with genotypes had a highly significant effect on sorghum green fodder yield and grain yield (t/fad (fad=2400 m 2 )). Variation among parents, crosses, parents vs crosses, lines, testers and line × testers also was observed in several sorghum studies such as Hovny & El-Dsouky (2007), Abdel-Mottaleb (2009), Essa (2009 and Mahdy et al (2011). …”

ETEROSIS and combining ability for grain yield and some …….agronomic traits were studied among thirty F1 grain sorghum crosses and their elven parents under three NPK levels during 2014 and 2015 seasons. Significant differences among genotypes were found for all studied traits, indicating wide genetic diversity. The interaction of genotypes with each of years and NPK levels were significant in most studied traits. The analysis of variance for combining ability revealed that the mean square due to entries, parents, parents vs. crosses, crosses, lines, testers, lines × testers turned up significant for all studied characters and suggesting that the experimental materials possessed considerable variability that both general and specific combining ability were involved in the genetic expression of these characters. The female line ICSB610 showed significant and negative general combining ability (GCA) effects for days to 50% heading and panicle length and positive for grain yield and plant height. It may be used to develop high yielding, early flowering, and tall hybrids with short panicles. For specific combining ability (SCA), effects, the crosses ICSA613 × ICSR89028 and ICSA20 × ICSR53 gave positive and highly significant SCA effects which indicated that these crosses can be considered desirable combiners. These crosses had also high grain yield per se and one of the parents with highest GCA effects. The observations on portioning of combining ability variance into additive and dominance variances indicated the role of both additive and dominance gene action. The magnitude of non-additive variance was higher than the additive variance by many folds for all studied traits.

Development of molecular markers linked to barley heterosis

The use of a three-line breeding system based on cytoplasmic male sterility has a great potential for hybrid production in barley. Hybrid vigour, or heterosis, which is an advantage of the offspring as compared to two parental lines, is one of the major factors for the success of the use of hybrids. In this study, gene differential expression profiles between barley hybrids and their parents were analysed by cDNA-AFLP analysis using forty eight crosses. Five transcript-derived fragments (TDFs) showed significant effects on heterosis of 1,000-kernel-weight, one of the major yield components. These five TDFs were successfully validated in different crosses by eliminating crosses with lower heterosis and thus can be used in breeding programs.
