    Notes: Processing variables affecting toasted wheat properties were studied. For maximum gelatinization of starch, substantial moisture, up to 60% of the weight of the dry wheat, must be infused into the whole kernel and equilibrated prior to the heat treatment. Moistening, tempering and toasting optima were established. Cold paste viscosities can be reduced by over-toasting, as well as under-toasting. Heating rates must maximize starch gelatinization before moisture is evaporated. Enzyme inactivation, which affects storage stability as well as viscosity values, was not complete in 20 set at 300°F (mass-avg kernel temp 275°F) but was complete in only 15 set at 400°F (tMA= 323°F). Toasting expands the kernel twofold or more and creates a porous endosperm structure which absorbs water readily. Several applications were tested, such as soup and sauce thickeners, breaders and cereals for domestic and foreign feeding programs.

    Notes: The successful detachment of sweet corn kernels as intact kernels promises large yield and effluent advantages over cut kernels during processing but requires a low strength of kernel attachment to the cob. This work describes the development of a test method for measuring the strength of kernel attachment and applies it to the identification of %varietal differences. Two components resisting detachment were identified: a base or abscission component and a side or frictional component. Base components as low as 1.3 Newton (N) (Golden Happiness) and as high as 5.5N (Illini Xtra Sweet) and side components as low as 1.3N (Vanguard) and as high as 4.0N (Golden Happiness) were observed. Abscission strength was found to correlate with prototype machine processing variables such as kernel mass production rates and the completeness of kernel removal from the cob.

    Notes: — Drying food pieces in a centrifugal fluidized bed with relatively high air flows may be self-limiting, even when only partial drying is desired. Rate increases obtained in early stages of drying may be more than offset through rate-retarding effects of a skin-like layer of collapsed surface tissue which forms on the pieces. This skin layer becomes increasingly resistant to heat and moisture transfer. Rate data and piece temperature patterns for potato, apple and carrot confirm visual observations that skin barriers 0.2–1.0 mm thick form in the first 8–10 min of drying with high air velocities and moderate temperatures. When air temperatures were 250°F with velocities of 15 fps, 1.2-cm cubes of potato could be blanched in only 6 min, suggesting a procedure for blanching some types of food products without leaching.

    Notes: The greenbug, Schizaphis graminum (Rondani), is the most economically damaging aphid pest of wheat in the southern Great Plains of the USA. In this study, the single, dominant greenbug resistance gene, Gb3, was molecularly tagged and genetically mapped using amplified fragment length polymorphism (AFLP) and simple sequence repeat(SSR) markers. Three AFLP loci were associated with the Gb3 locus in linkage analysis with 75 F2:3 families from the cross between two near-isogenic lines (NILs) for Gb3,‘TXGBE273’ and ‘TXGBE281′. Two of these loci, XMgcc Pagg and Xmagg Patg cosegregate with Gb3 in the population analysed. Further analysis indicated that XMgcc Pagg and Xmagg Patg are specific for the Gb3 locus in diverse genetic backgrounds. Two SSR markers, Xgwm111 and Xgwm428 previously mapped in wheat chromosome 7D, were shown to be linked with Gb3, 22.5 cM and 33.1 cM from Gb3, respectively, in an F2 population of ‘Largo’בTAM 107’, suggesting that Gb3 is located in the long arm of chromosome 7D. The two AFLP markers cosegregating with Gb3 are valuable tools in developing molecular markers for marker-assisted selection of greenbug resistance in wheat breeding.

    Notes: Relatively little is known about host-plant insect-resistance genes. Near-isogenic lines (NILs) can be a useful tool in evaluating such genes and their mechanisms of action. Through backcrossing and single-seed selection, NILs have been produced in wheat (Triticum aestivum L.) for resistance/susceptibility to biotype-E greenbug, Schizaphis graminum (Rondani). Crosses among several resistant and susceptible NILs produced segregation patterns in the F2 generation that were inconsistent with simple monogenic inheritance. The simplest genetic hypothesis consistent with the data would involve two independently segregating loci, requiring complementary expression of multiple resistance alleles. F3 segregation data were also consistent with the proposed genetic hypothesis. Multiple alleles are required to account for the observed variation, although the source of the multiple alleles is unknown. Direct comparison of specific resistant/susceptible pairs of NIL's, as well as bulked segregant analysis, should permit elucidation of resistance mechanisms. Based on the segregation data presented, new designations for the resistance loci studied are proposed.

    Notes: The rotational streaming of cytoplasm in barley root hairs has been stimulated about 1.3–1.8 times through continuous treatment with various solutions of myo-inositol. The stimulation attained the same level as after ATP administration and was dependent on the external myo-inositol supply with the employed concentrations. The stimulation was cut off by simultaneous treatment with myo-inositol and uranyl salts. By using uranyl acetate the rate of streaming was maintained about the value of the control. The uranyl chloride caused an inhibition in the rotational streaming and later made it to cease altogether. The simultaneous treatment with myo-inositol and 2.4-DNP (dinitrophenol) induced a quick inhibition in 60% of the root hairs. consecutively stopping rotational streaming.It is assumed that the stimulation of rotational streaming is not due to the direct effect of myo-inositol but to ATP formed in the reaction: inositol hexaphosphate ++ ADP ↔ ATP + inositol. According to the results obtained by testing with uranyl salts, the phosphorylation of inositol probably takes place at the cell surface. The effect of 2,4-nNP points to the presence of two competitive metabolic processes involved in ATP consumption: the upkeep of rotational streaming and the uptake of substances by the plant cell.
