Trends changes of oat genotypes, grown in lithuania

Abstract

A study was carried out at Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry. A total of 37 oat (Avena sativa L.) genotypes, which had been registered, grown or selected in Lithuania over the period 1934–2013 were analysed. Precision field trials were conducted. Conventional technology for oat cultivation was employed. The relationship between oat genotypes and year of registration, growth and selection was calculated. The greatest progress of oat genotypes registered, grown or selected in Lithuania was in the increase of yield (R = 0.73), hectolitre weight (R = 0.53), and plant height decrease (R = −0.57); the highest decrease was found in protein content (R = −0.55). The new cultivars tended to show a higher thousand grain weight, better resistance to lodging, higher starch and lower fat content, lower resistance to crown rust.
