Estimation of Breeding Parameters from Phenotypic Data of F4:5 RIL in Ethiopian Malt Barley (Hordeum distichum L.) Breeding Population

Table 2

List of agronomic and quality parameters collected.

SN	Variables	Code	Nature of Variables	Collection method
1	Heading date	DH	Quantitative	Number of days from date of sowing till about 75% of plants in the plot was flowering
2	Maturity date	DM	Quantitative	Number of days from sowing to the date when 75% of the peduncle turned to yellow straw color and when no green color remained on glumes and peduncles of the tagged plant
3	Plant height	PH	Quantitative	The actual measurement of plant height from ground level to the tip of the spike excluding the awns and recorded as the average of five randomly selected plants in each plot
4	Thousand kernel weight	TKW	Quantitative	Weights were measured by taking the mass of carefully counted a thousand kernels on sensitive electronic balance (±0.1 g) after kernels were adjusted to 12.5% moisture content
5	Grain protein concentration	GPC	Quantitative	Total protein content in the grain, expressed as a percentage. estimated using the NIRS machine
6	Malt extract	ME	Quantitative	Solid material extracted from finely ground malt, expressed as a percentage. estimated using the NIRS machine
7	Friability	FR	Quantitative	Indicator of endosperm modification after malting by a simple milling test in a friabilimeter, expressed as a percentage. estimated using the NIRS machine
8	Beta-glucan	BG	Quantitative	a principal constituent of the barley endosperm cell wall, expressed as mg/estimated using the NIRS machine
