“…Barley production can be increased either by bringing more area under cultivation or by developing new high yielding cultivars. Since area is a limiting factor, new barley varieties with high genetic potential for grain yield needs to be developed, for which several breeding procedures have been established (Ramage, 2011;Friedt et al, 2011). Varietal improvement through plant breeding depends upon the genetic information available from parents and their cross combinations governing qualitative and quantitative traits.…”

Studies on genetic control of grain yield are of great importance for devising effective breeding programmes for yield gain in barley. Hence, inheritance of grain yield, heterosis and combining ability were investigated in barley population obtained from half-diallel crossing among 7 parental lines. The analysis of variance revealed that mean squares due to genotypes were highly significant for grain yield indicating wide diversity among the parental materials used in the study. Mean squares of general combining ability (GCA) and specific combining ability (SCA), the ratio of GCA to SCA mean squares and portion of additive and dominance variances showed, importance of both additive and non-additive gene effects for grain yield. The non significant ratio of GCA to SCA mean square highlighted that non-additive gene effects were more important than additive effects. Distribution of dominant and recessive alleles in parents were asymmetrical and parents possess majority of recessive alleles. Since average degree of dominance has values greater than 1, which indicated over-dominance type of gene action in the inheritance of the grain yield. The parent BHS400 was considered suitable according to its yield capacities and general combining ability effects. Only 2 crosses viz., BHS400 X RD2660 and BHS400 X RD2552 had significant higher grain yield than that of the check variety (BHS400), high significant SCA values and high significant useful heterosis values. Considering average narrow-sense heritability and over-dominant effects in genetic control of grain yield it is better to postpone selection for this trait until advanced breeding generations.

“…Barley is one of the world's oldest and most important crops (along with wheat, rice, and maize) (Ramage 2011). It plays a significant role in the global economy, particularly as animal feed (which accounts for approximately 70% of barley harvests), in malt and alcohol production (about 21% of barley harvests), as a basis for nutritional products (to a lesser extent) (maRcus 2013), and more recently as a feedstock for biofuel production (gRiffey et al 2010).…”

Wykorzystanie niezmienników momentowych Hu i momentów Zernike’a do rozpoznawania ziaren jęczmienia dwu- i sześciorzędowych

Rozpoznawanie odmian ziaren jęczmienia jest zadaniem skomplikowanym i jednocześnie istotnym z punktu widzenia gospodarki. Szczególnie istotna jest identyfikacja ziaren należących do klas dwurzędowych i sześciorzędowych ze względu na właściwości którymi się wykazują, takimi jak zawartość białka, czy skrobi. W różnych zastosowaniach cechy te mają swoje znaczenie. W niniejszej pracy uwaga zostanie skupiona na wykorzystywaniu metod, takich jak momenty Zernike i momenty Hu, w kontekście rozpoznawania kształtu obiektów. Dokonano oceny skuteczności identyfikacji ziaren jęczmienia dwurzędowych i sześciorzędowych z zastosowaniem niezmienników momentowych (Hu i Zernike) w połączeniu z klasyfikatorami: liniowym i SVM z jądrem liniowym, radialnym, wielomianowym i sigmoidalnym. Zastosowanie momentów Zernike i klasyfikatora SVM z jądrem RBF pozwoliło uzyskać dokładność na poziomie 99,2%, w porównaniu do 98,5% uzyskanych dzięki zastosowaniu niezmienników momentu Hu.
