Early Maturing

The comparative growth, phenology, and yield components of three early-maturing barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.) cultivars were studied during the 1989–1991 growing seasons at Palmer, Alaska. Barley cultivars produced an average of 1.1 more leaves than wheat, and had a smaller (4.5 growing degree days/leaf) phyllochron interval. The early maturity of barley relative to wheat was due mainly to its ability to fill and ripen grain under cool conditions.Key words: Barley, wheat, subarctic, phyllochron

Days To Maturity

The purpose of this research was to compare assessments of maturity in barley (Hordeum vulgare L.) using growing degree days to maturity based on visual head color and percent grain moisture. Twelve barley cultivars were evaluated for 3 yr at Palmer, Alaska, using three harvest dates. Phenotypic and environmental correlation coefficients between growing degree days to maturity and grain moisture at harvest were high, and tended to be highest at earlier harvest dates.

Northern Alberta

Two spring barley (Hordeum vulgare L. emend Lam.) and three spring wheat (Triticum aestivum L.) cultivars were grown over a 2-yr period at three locations in Alberta north of latitude 53°N, to compare the effect of fall and spring seeding on yield and maturity. The cultivars were Olli and Jubilee barley, and Park, Thatcher, and Pitic 62 wheat. The locations were Edmonton, Beaverlodge, and Fort Vermilion. With few exceptions, fall seeding resulted in loss of yield compared with spring seeding, and the fall-seeded materials were no earlier maturing than the comparable spring-seeded materials. For the cultivars and locations studied, fall seeding of spring barley and wheat cannot be recommended. Two spring seeding dates were also compared, the first being considerably earlier than typical commercial seeding at the same location. There were few significant differences in yield between the two spring dates, but the later date considerably delayed the maturity of all cultivars.

Four trials with 18 triplet combinations of tall, intermediate and short cultivars of spring wheat, and four trials with 18 triplet combinations of one short and two tall cultivars of spring barley, were conducted over 3 yr at Saskatoon to test the hypothesis that differences in height would not cause interplot competition for grain yield. Significant competition between cultivars was detected in two trials with wheat and in one of the barley trials.Key words: Wheat (spring), Triticum aestivum L., barley (spring), Hordeum vulgare L., interplot competition, grain yield

A eld experiment was conducted during rabi seasons of 2015-16 and 2016-17 to study the accumulated growing degree days (GDD), helio-thermal unit (HTU), photo-thermal unit (PTU), heat use efciencies (HUE) at different phenological stages and performance of wheat (Triticum aestivum L.) varieties grown under different sowing dates. Results of present study revealed that the crop sown on 20th October required maximum calendar days, growing degree days, photo-thermal unit and helio-thermal unit for tillering, owering, earing and maturity which was signicantly reduced with subsequent delay in sowing time. The grain yield recorded in 20th November (4065 kgha-1) was statistically at par with 5th November yield (3863 kgha-1). The signicant reduction in grain yield on varieties was recorded when sowing was delayed beyond 20th November. Among the varieties 'VL-907' produced highest grain yield(3771 kgha-1) which was statistically on par with 'VL-829' (3726 kgha-1). The early and timely sown wheat  variety like VL-829 and VL-907 took highest calendar days, GDD, HTU and PTU for earing and maturity. The variety 'VL-907' recorded the highest grain yield (4196 and 4168 kgha-1) at 5th and 20th November sowing as compared to all other sowing dates.

Selection Decisions

Abstract Wheat stem sawfly, [Cephus cinctus (Hymenoptera: Cephidae)], females display complex behaviors for host selection and oviposition. Susceptible hollow stem wheat (Triticum aestivum L.) cultivars release a greater amount of attractive compound, (Z)-3-hexenyl acetate and receive a greater number of eggs compared to resistant solid stem wheat cultivars. However, barley (Hordeum vulgare L.) is becoming a more common host for C. cinctus in Montana. Therefore, how do host selection and oviposition behaviors on barley cultivars compare to what happens when encountering wheat cultivars? To answer this question, we carried out greenhouse experiments using two barley cultivars: ‘Hockett’ and ‘Craft’. Between these cultivars at Zadoks stages 34 and 49, we compared host selection decisions using a Y-tube olfactometer, compared oviposition behaviors on stems, and counted the number of eggs inside individual stems. In Y-tube bioassays, we found a greater number of C. cinctus females were attracted to the airstream passing over ‘Hockett’ than ‘Craft’ barley cultivars. Although the frequencies of oviposition behaviors were similar between these cultivars, the number of eggs was greater in ‘Hockett’. Volatile profiles indicated that the amount of linalool was greater in the airstream from ‘Craft’ than in ‘Hockett’ at Zadoks 34 while the amount of (Z)-3-hexenyl acetate was greater in airstream from ‘Hockett’ at both Zadoks 34 and 49. These results suggest that volatiles of barley plants influenced host selection behavior of ovipositing C. cinctus females, while other discriminating behaviors do not differ between cultivars.
