APPRAISAL OF YIELD AND QUALITY TRAITS IN TWO AND SIX ROWED BARLEY

Abstract

Ten barley genotypes were evaluated for yield and quality traits and found significant variance among these traits. Mean variance study revealed that protein (12-13%), starch (59-60%), wet gluten (8-9%) and dry gluten (3-3%) values were at par in both six and two-rowed barley, while 1000-grain weight (47-43g), test weight (61-58kg/hl) and gluten index (96-91) were greater in two rowed, whereas falling number values (263-261sec) were slightly higher in six rowed. Significant positive associations were found among starch, protein, and falling number values (FNV), whereas 1000-grain weight (GW), test weight (TW), gluten index (GI), wet gluten (WG), and dry gluten (DG) revealed positive links in 2-rowed and 6-rowed barley. Based on a principal component analysis (PCA), barley genotype “B-21034” was found in the first quadrant group with the highest values and positively correlated with GI, WG, DG, and GW. B-21008 and B-21022 were noted in the second quadrant with positive correlation with TW. PCA also showed that FNV and TW are far apart, whereas protein and starch reported in the fourth quadrant are too close. PCA revealed that genotype B-21034 showed highest index of WG, DG, GI and GW in first quadrant and can be utilized in breeding programs. For industrial purposes, Sultan-17 may be the best option due to highest values of starch and protein.
