“…Two other genes, TaMKK3 and TaVp1, were selected for investigation due to literature that indicates these two loci can have a large impact on PHS susceptibility (Shorinola et al, 2016;Torada et al, 2016). The larger kernel size of the susceptible allelic group may contribute to a higher FN and lower a-amylase levels because it is likely that the scutellum of larger grains accounts for a smaller percentage of the total volume when compared with smaller kernels (Nik, 2011). This was confirmed by Shorinola et al (2016) via fine mapping of the 4AL QTL region.…”

“…For example, the group with the susceptible allele had significantly higher FN and larger kernel diameter, with trends towards lower a-amylase concentrations and higher kernel weight. The larger kernel size of the susceptible allelic group may contribute to a higher FN and lower a-amylase levels because it is likely that the scutellum of larger grains accounts for a smaller percentage of the total volume when compared with smaller kernels (Nik, 2011). This could lead to less total a-amylase, as a-amylase is initially produced in the scutellum, and higher FN, possibly due to the greater starch content in a sample of large kernels relative to a comparably sized sample of small kernels (Ranki and Sopanen, 1984).…”

Allelic Impacts of TaPHS1, TaMKK3, and Vp1B3 on Preharvest Sprouting of Northern Great Plains Winter Wheats

Preharvest sprouting (PHS) of bread wheat (Triticum aestivum L.) is a common problem that can lead to negative economic impacts arising from yield loss and undesirable end‐use quality. Twenty‐one winter wheats adapted to northwestern Montana were grown over two field seasons and used to assess three loci observed in previous studies to have moderate to large impacts on PHS. The main goal was to validate the usefulness of TaPHS1‐3A (a Mother of Flowering Time‐like gene), TaMKK3‐4A (a mitogen‐activated protein kinase kinase 3), and Vp1‐1B (Viviparous 1) in breeding for modified dormancy before harvest, as well as to determine their potential relationships to agronomic and seed traits, specifically, falling number and α‐amylase concentrations. Variation in PHS susceptibility across entries ranged from 0% sprout (fully dormant) to 95% sprout (fully nondormant) after 7 d of wetting. Most entries showed an intermediate level of sprouting susceptibility ranging between 10 and 50% sprouted. Alleles previously reported to impact dormancy were found for all three genes but TaPHS1 was the only locus found to be significantly associated with PHS. It is unclear whether variation caused by TaPHS1 may be masking the effects of the other loci, but it is evident that TaPHS1 could be used in a breeding program to modify the level of seed dormancy in winter wheat before harvest.

“…Early vigour may be associated with both larger leaves and quicker ground cover of leaves and tillers ( Mullan and Reynolds, 2010 ), which are partly determined by embryo size and environmental growth factors (e.g. temperature and soil moisture) ( Mohsen et al , 2011 ; Rebetzke et al , 2014 ).…”

“…However, this was contradicted by (Fauzi et al 2021) for the germination percentage. This variation in seedling traits may attributed to the embryo area (Mohsen, 2011) along with the availability of more amounts of food reserves provided to the embryonic plant (Ellis, 1992). It was suggested that embryos embedded inside of seed are the main drivers of germination vigour because it depends on the quality of the messenger RNA stored during embryo maturation on the mother plant (Rajjou et al 2012).…”

Rice is everyday meal of about half of the world's population. Demand for rice is continuously growing because of increasing population. With the impact of climate change, rice crop needs to be diversi ed with direct seeded cultivation. Under direct seeded condition seeds of high seedling vigour and good crop stand are preferred. Therefore, the following study was undertaken to analyse the seed traits and its effect on seedling vigour and grain yield in rice wild species. It was found that large seeds have larger embryos and better seedling vigour. Signi cant positive correlation found between embryo area grain yield, germination percentage nodal root number and seedling height. The cultivated Oryza sativa genotypes had largest embryo area and seed area followed by Oryza meridionalis. Oryza glaberrima had the smallest embryo area. The seed size was observed to be evolved under selection pressure. Bigger seed sizes in the Oryza sativa cultivars indicate gradual selection for increased seed size and tness under agronomic condition.
