Performance and characteristics of barley germplasm with wild barley allele introgression

Data of 20 traits measured on a collection of 118 barley germplasms in field trials conducted over the three years 2020-2022. The trials were conducted in a range of environments, with different rainfall across four states (SA, VIC, NSW, WA).

The dataset comprises: (1) Trial information for all sites across 3 years, including experimental design and trial management data; (2) Raw phenotypic data; (3) Markers and genotypic data for the set of tested germplasms. 20 traits were measured, including:

• Early establishment (in counts, the average of the number of emerged plants recorded on 50 cm distance of two rows for three times per plot)
• Early establishment per m2
• Days to booting (days from sowing to awn peep 1cm, in days),
• Plant height (distance from the ground to the tip of the awn, in cm),
• Fertile and total tiller number from harvest cut and per m2 (TIN, in counts),
• Grain number per ear (GPE, which was the average grain number per ear of 15 ears randomly selected from each plot, excluding flat and undeveloped grains, in counts),
• Number of abnormal grain/ear
• Thousand-grain weight (TGW, weight of thousand grains, in g),
• Test weight (weight of the seeds in a hundred litre, in kg/hL),
• Harvest index (HI, percentage of weight of plot grain weight from the harvest cut to the total above-ground dry mass, in %),
• Dry biomass
• Screening (percent of grain that was small enough to pass through the 2.2 mm sieve),
• Lodging (1-9 scale, with 1 is plant standing straight and 9 is the plant lying on the ground, in number),
• Final grain yield (Grain weight from a plot per plot size and kg/m2 and then convert to t/ha)

Additionally, disease incidence for net form (NFNB), spot form of net blotch (SFNB), and barley leaf rust (BLR) were also recorded if present. The scale for rating diseases is 1-9 with 1 is no symptoms of diseases and 9 is heavily infested with diseases.
