| Description |
The present study was undertaken to determine genetic variability present in relation to seed traits, yield and malt characters with the objective to study their association contributing to grain yield and malt yield in barley. Genetic analysis of grain yield components, malt and seed characters were conducted on 20 genotypes grown in a randomized block design with three replications at CCS Haryana Agricultural University, Hisar during rabi 2010-11. Observations were recorded for grain yield components, malt and seed characters. The seed characters were recorded in seed testing laboratory of Department of Seed Science & Technology, CCS HAU, Hisar and malt characters were analyzed in micro malting lab at Directorate of Wheat Research, Karnal. Wide range, high coefficients of variation, heritability and genetic advance as percent of mean were recorded for grain yield, tillers/plant, number of grains/spike, electrical conductivity, husk content, grain plumpness and â-glucan content revealed the possibilities of their further improvement following simple selection methods. Two rowed type barley genotypes had high mean values for days to heading, tillers/plant, 1000 grain weight, test weight, grain plumpness, protein content, â-glucan content, malt yield, hot water extract, standard germination, seedling length, accelerated ageing, electrical conductivity, field establishment and seedling vigour showing that two rowed barley genotypes are best for malt. BH 393, BH 932, BH 902, RD 2552 among six rowed barley and DWRUB 52, BH 885,DWR 91, BH 927 in two rowed barley are some of the promising genotypes which should be involved in further breeding programme in barley. Considerable amount of variation was found in material under study. Grain yield was found positively and significantly correlated with days to maturity and grains/spike. Grain yield/plant found positive and significant correlation with malt yield, hot water extract in six rowed barley. Accelerating ageing was found positively and significantly associated with malt yield. These desirable correlations showed that number of grains/spike and days to maturity were the major yield components and higher grain plumpness, malt yield and hot water extract and low protein content, husk content and â-glucan content were the major malting traits among genotypes of both two rowed and six rowed barley. |
