Inheritance of agronomic and seed composition traits in Glycine max x Glycine soja crosses

Interspecific crosses between the cultivated soybean, Glycine max (L.) Merr., and the wild species. Glycine soja Sieb. & Zuce, may be useful for broadening the genetic base of commercial cultivars. The objectives of the study were to evaluate agronomic traits of G. max, G. soja and their F1 hybrids in tropical and temperate environments, to determine whether cytoplasmic effects were present for agronomic traits and seed composition in reciprocal crosses between the two species, and to evaluate the type of gene action that controls the inheritance of traits in interspecific crosses. Reciprocal crosses were made between 'Century' and PI326581 and between 'Amsoy 71' and PI424001. Thirty plants of each of the parents and 50 F1 plants of each cross were grown at two environments in Puerto Rico and one in Iowa. The traits evaluated were date of stages R1 and R8, leaf size, shattering, defoliation, vining, lodging, agronomic type, plant height, 100-seed weight, percentage of seed protein and oil, and percentages of palmitic, stearic, oleic, linoleic, and linolenic acids in the oil. No significant differences were observed among environments for seven of the 11 agronomic traits evaluated in the two crosses. The relative performance among genotypes for all traits in Iowa and Puerto Rico was similar. This similarity indicates that it is possible to use tropical locations to evaluate the progeny of interspecific crosses. No significant differences between F1 plants of reciprocal crosses were observed in the two crosses for any of the traits; thus, cytoplasmic effects were not important. The type of gene action observed differed among traits and included additive, dominance, and partial dominance.

Five parent populations of faba bean, differing in reaction to rust disease, were crossed to prepare a complete diallel of F1 hybrids. Detached leaves of the parents and F1 hybrids were challenged with 3 Australian rust populations and symptom development was monitored from 11 to 16 days after inoculation, using a disease score related to the percentage of leaf area covered with pustules, and a nominal value for pustule size. Additive gene action was very important in determining the response to rust disease, with ILB 3025 and ILB 3107 having similar low disease scores, Fiord and Acc 327 having high values, and Icarus an intermediate value. Cytoplasmic effects were also critical, with ILB 3025 having the most susceptible cytoplasm and ILB 3107 the most resistant, and this was most readily detected in terms of the size of the pustule. Heterosis conferred slightly lower disease scores and dominance was significant but of lesser importance than additive gene action, particularly for disease score. Rust population host gene action interactions were significant by the end of the observation period, but were much smaller than the main effects. The hybrid ILB 3107 ILB 3025 had less disease development than either parent, indicating the potential for developing more resistant cultivars using transgressive segregation. ILB 3107 shows particular promise for use as a female line as it had both nuclear and cytoplasmic factors to contribute to the development of resistant cultivars.

SummaryLines of mice have been divergently selected for over forty generations on either body weight or fat content. Reciprocal crosses were made between the divergent lines and the offspring backcrossed to the parental lines. The resulting data allowed us to investigate the genetic basis of response, including two features of particular interest: (i) the relative contribution of autosomal and sex-linked genes and whether any significant Y chromosome or cytoplasmic effects were present (ii) the mechanism of gene action, whether predominantly additive or whether significant dominance effects were present. A large additive sex-linked effect was observed in lines selected on body weight which accounted for approximately 25% of the divergence. The remaining 75% of the divergence appeared to be autosomal. There was no apparent sex-linked effect in lines selected on fat content and the response appeared to be entirely autosomal and additive.

AbstractObtaining corn hybrid seeds (Zea mays L.) with high vigour depends on the parental lines and the direction of the cross, and this relates to seed desiccation tolerance and composition. This research studied reciprocal crosses between pairs of proprietary, elite parent lines (L1 and L5; L2 and L4) producing hybrid seeds with different qualities attempting to correlate vigour with seed composition, focusing on storage proteins, starch and soluble sugar amounts. Four corn hybrid seed lots produced from reciprocal crosses were compared (HS 15 with HS 51, and HS 24 with HS 42) by assessing germination, vigour, and seedling emergence in the field. Seed composition was assessed in mature, dehydrated seeds. Proteins were extracted, quantified, and analysed by electrophoresis and densitometry. Starch amounts were assessed using a kit and soluble sugars were determined using high performance liquid chromatography with pulsed electrochemical detection. The L1 and L2 lineages, used as female parents, provided seeds with lower vigour; however, the quantification of major protein bands, and sucrose, raffinose and stachyose were similar between seed lot pairs. While both total seed protein and starch varied between reciprocal hybrids for one of the two sets of crosses, the amounts of neither correlated with seed vigour. Interestingly, hybrids with low seed vigour (HS 15, HS 24) accumulated greater amounts of fructose relative to their reciprocal; correlation analysis confirmed these results. We demonstrate different effects on seed vigour dependent on the maternal parent in reciprocal crosses producing hybrid corn seeds. We also show that vigour is negatively correlated with seed reducing sugar contents.

ABSTRACT When different gene groups are combined by hybridization, the expression of predominant genes for a trait must be known. This understanding is fundamental to the decisions made by breeders in the stages of cultivation and selection of segregating populations during the breeding program. Thus, the objective of this study was to determine the effects of combining ability and gene action for the root distribution traits of the Andean and Mesoamerican common bean gene groups. Six common bean parents from the Andean and Mesoamerican groups were hybridized in a complete diallel mating scheme, resulting in 30 F1 hybrids. The parents and hybrids were planted in the field in a simple lattice design. The target trait was root distribution, calculated as the relative number of roots in the topsoil. The effect of the general combining ability was significantly higher than that of the specific combining ability (58%) and the reciprocal effect (41%). Particularly, the combination estimates were modified according to the order of the gene groups used. The combinations IPR Uirapuru x BAF53 (Mesoamerican x Andean), BAF53 x CBS14 (Andean x Andean), and CBS14 x IPR Uirapuru (Andean x Mesoamerican) mainly exhibited an increase in the mean root distribution. However, the highest fraction of genetic variance correlated with additive components (60%), even in crosses involving different gene groups. Consequently, the additive gene action was predominant in the expression of root distribution trait in common bean, irrespective of the gene group used.
