Basic Information

A study of the relationships among 29 different wheat (Triticum aestivum L.) kernel and flour measurements indicated that only 3 (kernel hardness, protein quantity and rate of dough development) were necessary to provide the basic information required for estimation of the bread and (or) pastry quality potential of a cultivar. Further, information on wheat quality contained in the remainder of the measurements could be interpreted as functions of these three basic factors.

Grinding Time

Kernel hardness, measured as grinding time, of seed from plant-rows extracted from the spring wheat (Triticum aestivum L.) parents of a previous study, showed that Cal 3, thought to have had medium-hard kernels, was in fact a mixture of soft and hard plants plus a few intermediates. This explains unexpected results. Parents Cal 9, Cal 25 and Cal 13 were each homogeneous for plants with soft, hard and very hard kernels, respectively.Key words: Wheat, Triticum aestivum L., medium-hard kernels, grinding time, genetics

Photoperiod Insensitivity

HY355, white spring wheat (Triticum aestivum L.) combines high grain yield, normal height and photoperiod insensitivity. HY355 is heterogeneous for kernel hardness with 55% of the breeder lines rated hard and 45% rated soft. HY355 is the first registered wheat cultivar eligible for grades of Canada Prairie Spring (white). It received a 2-yr interim registration on 6 May 1988.Key words: Wheat (spring), cultivar description

Kernel Protein

Ninety-nine F4 lines from the cross Lennox × Stadler of common wheat (Triticum aestivum L.) ranged widely in both kernel hardness and kernel protein content. A nonsignificant correlation of r = −0.17 showed the absence of any tendency for hardness and high protein to be associated, contrary to what might be expected from the association found in commercial cultivars.

Hard Spring Wheat

Kernel hardness, one of the most important factors in determining the end-use suitability of wheat (Triticum aestivum L.), is largely influenced by puroindoline proteins a (PINA) and b (PINB). Soft texture is wildtype (Pina-D1a/Pinb-D1a) with hard texture being determined by either Pina-D1 gene deletion or point mutations in Pinb-D1a. The objectives of this study were to determine kernel hardness indices (HI) and Pina-D1/Pinb-D1 allelic diversity in a diverse set of 81 Canadian (representing eight wheat classes) and 49 US hard spring wheat varieties. Varieties were grouped into two experimental sets grown in replicated trials in 2004–2006 at Saskatoon, SK. Variation existed among varieties with HI means ranging from 21.7 (CDC Zorba) to 72.7 (AC Morse) in exp. 1 and from 25.0 (HY320) to 66.1 (Norlander) in exp. 2. Only AC Andrew, CDC Zorba, and Red Fife were soft kernel textured and carried the wildtype Pina-D1a/Pinb-D1a alleles. The majority of Canadian varieties were Pina-D1a/Pinb-D1b (69%), while a greater frequency of US varieties was Pina-D1b/Pinb-D1a (55%). Only four varieties, all from Quebec-based breeding programs, carried the Pinb-D1c allele. On average, varieties with the Pina-D1b allele had significantly harder kernels than those carrying the Pinb-D1b mutation. Durum wheat (T. turgidum L. var durum) varieties, included as hard-kernelled controls, possessed significantly harder kernels (average HI = 71.2) than spring wheat varieties with Pina-D1b (65.3). Varieties carrying Pina-D1b (null PINA) were harder than those carrying hardness mutations at the Pinb-D1 locus, but considerable overlap in hardness was evident among genotypic classes. This work represents the first extensive Pin genotyping combined with HI phenotyping survey of Canadian wheat varieties, which is expected to aid breeders in understanding how Pina-D1/Pinb-D1 allele composition is currently associated with kernel hardness across Canadian wheat classes.

Grinding Time

Significant variation among grinding times of F3-derived F4 lines of five crosses indicated that there were genetic differences in hardness among five spring wheat (Triticum aestivum L.) cultivars. Bimodal distributions indicated a two-gene difference between a very hard and soft cultivar and a one-gene difference between a hard and soft cultivar.

Flour Protein

Early generation screening tests for bread wheat quality, including flour protein and various mixograph measurements, and final evaluation measurements, including Remix Loaf Volume and Baking Strength Index, were obtained for 250 samples of spring wheat (Triticum aestivum L.) grown in various locations in 1974. Multiple regression analysis was used to study the relationships between prediction tests and final tests and to develop rules for predicting Remix Loaf Volume and Baking Strength Index. A linear function of flour protein content and mixograph development time was found to be most suitable for predicting Remix Loaf Volume while consideration of the relative magnitudes of these two characteristics was best for predicting Baking Strength Index. The rules developed from an analysis of the 1974 data were tested by applying them to data from 328 samples grown in 1975.

Endosperm Texture

Early-maturing spring wheat germplasm lines CDC EMDR-4, CDC EMDR-9, and CDC EMDR-14 have high levels of seed dormancy. Their agronomic performance is comparable to that of the cultivar Columbus. These three lines had similar grain protein concentration and kernel hardness relative to the check cultivars, except CDC EMDR-4, which had a soft endosperm texture.
