Abstract:
The aim of this research was (i) to evaluate the oat genotypes for grain yield and physiological
traits, (ii) to investigate the oat genotypes having the highest grain yield in the conditions of
research region and the influence of these traits on grain yield. This research was carried out
using 10 oat cultivars, sown in a randomized complete block design with four replications,
between 2014 and 2015 in experimental fields of ATTC Fushe Kruje, Albania. In the
research, leaf area (LA), leaf area index (LAI), net assimilation rate (NAR), crop growth rate
(CGR), dry matter (DM), grain yield (GY) and harvest index (HI) were investigated. According
to the results obtained, cultivars were significantly different for all investigated traits. The
highest grain yield 53.5 kv/ha was produced by the Torpan cultivar. Physiological growth traits
(LA, LAI, NAR, and CGR) increased gradually from vegetative stage and reached maximum to
booting stage. Total dry matter accumulation per plant gradually increase with crop age and
attained maximum a few days before maturity. The different values of physiological growth
traits impacted on different ways on grain yield. Not always the superiority of the cultivars for
physiological growth traits was accompanied with high yield. This was because of different
values of HI i.e. different ability to accumulate the dry matter to the grain. |
