“…One of the parents of population 2, IAC 7 has a superior industrial quality, with high β-glucan content (Crestani et al, 2012). The progeny originating from the cross between IAC 7 and UFRGS 19 showed individuals with average performance inferior to IAC 7 regarding the β-glucan content.…”

“…Parents were selected based on their contrasting β-glucan content in the grains to generate mapping populations. Here, we used a part of F 2 seeds derived from the crosses performed by Crestani et al (2012). In the cold season of 2009, a field experiment was carried out sowing 133 and 138 F 2 seeds of populations 1 and 2, respectively.…”

“…Human consumption of oats is becoming a major trend due to its excellent nutritional profile (Ahmad et al, 2014;Butt et al, 2008). Oats has high protein quality, antioxidant components, high lipid contents (especially unsaturated fatty acid) and high fiber rates (Biel et al, 2014;Crestani et al, 2012;Daou and Zhang, 2012;Marshall et al, 2013;Rasane et al, 2013).…”

Improvement of quality-related traits of grains is a constant concern in white oat breeding programs, which challenges breeders to understand their dynamics. The performance of different genetic combinations must be thoroughly evaluated to make high nutritional quality cultivars available. This study aimed to estimate the heterosis on F 1 and F 2 generations, vigor loss, due to inbreeding, and correlation between the grain chemical components to understand the dynamics of these traits, considering two segregating oat progenies. The populations Albasul × UPF 15 (population 1) and IAC 7 × UFRGS 19 (population 2) were developed. Both populations showed transgressive segregant individuals. The combination Albasul × UPF 15 provided significant heterosis for traits β-glucan total and soluble fiber contents, while the population obtained by crossing IAC 7 × UFRGS 19 generated significant gain by heterosis for total fiber, insoluble fibers and non-structural carbohydrate contents. Considering the F 2 average for each population, one can observe that population 1 presents higher β-glucan and lipid contents than population 2. On the other hand, population 2 has higher protein content than population 1. In both populations, the non-structural carbohydrate content is strongly and negatively correlated whith protein, total and insoluble fibers. Correlations between total fibers and lipids and between total fibers and insoluble fibers were both positive and high in both populations.

Two male sterile lines (Ms-1, Ms-2) and ten inbred lines (K3, K4, K5, K8, K13, K15, K17, K20, K30, K33) were crossed according to Comstock and Robinson's (in: Gowen (ed.) Heterosis, 1952) North Carolina Design II to estimate heterosis, combining ability, heritability and the phenotypic correlation coefficient for 11 ornamental characteristics of Tagetes patula. Twenty cross combinations and 12 parents were evaluated for 11 ornamental characteristics, in a randomized complete block design with three replications, in trials conducted during 2011 and 2012 at Huazhong Agricultural University, Wuhan, China. The results showed that the hybrid combinations displayed higher ornamental values and showed obvious heterosis over the male-parent for most of the ornamental traits evaluated. The male sterile line Ms-1 scored highly for general combining ability (GCA) with respect to the development of F 1 offspring with a dwarf and compact plant habit, abundant double petals, and extended period between the opening and wilting of individual inflorescences. The male sterile line Ms-2 scored highly for GCA with respect to the development of F 1 offspring with a large plant form and large flower size, as well as abundant flower numbers. The specific combining ability (SCA) of cross Ms-2 9 K20 was found to be high, with progeny showing high positive heterosis over the male parent and superior mean values for all ornamental traits, thereby indicating that this cross has the potential to function as a superior cultivar within commercial breeding programmes. Both GCA effects and SCA effects were found to be important for the performance of individual hybrid combinations, and no clear relationship between GCA and SCA was found for these T. patula lines. The ratio of r 2 GCA =r 2 SCA for individual characteristics revealed that the relative importance of GCA and SCA to progeny quality varied for different traits. Estimates of heritability showed that many of the quantitative ornamental traits of T. patula were highly heritable, and the traits of diameter of center disk and number of ray florets should readily be improved by selection. By contrast, environmental factors influenced markedly on the traits of plant height, crown size, number of days between opening and wilting of inflorescences and the maximum number of flowers present each day. Phenotypic correlation coefficient analysis showed that the various vegetative growth characteristics were closely related to one another and, more interestingly, significant phenotypic correlations were found between the growth of the vegetative and reproductive structures of T. patula.
