Investigation of grain yield and yield components of some field pea (Pisum sativum L.) genotypes in Mediterranean climate conditions

Abstract

The aim of present study performances of field pea genotypes and relationships among the morphological traits were evalation. The present research was conducted with 20 field pea genotypes at two locations including upland and lownland soil conditions under typical Mediterrananean climate in Turkey. Field trails at each location were organized in randomized complate blocks design with three replications during 2011-2012 and 2012-2013 growing period. Combined mean values over year and location for days to 50 % flowering, stem length (total pod number , grain number (number plant-1), 100-seed weight (g plant-1), seed yield (kg ha-1) and harvesting index (%) were 123.2 days, 81.4 cm, 14.7 number plant-1, 82.1 number plant-1, 18.4 g plant-1, 1176 kg ha-1, 35.5 % respectively. In this resarch obtained results showed that grain yields of genotype 102-Bursa, genotype 25-Denizli, Flavora, Ambasador, Sienna and Topaz with short stem lenght and days to flowering gave higher grain yield than the other varieties in both locations. Negative and significant correlations were found between grain yield and days to 50 % flowering, stem lenght. There were also positive and significant correlations between seed yield and harvesting index in field pea.
