A comparison of yield-related traits of Coriandrum sativum var. microcarpum DC. and Coriandrum sativum var. sativum

Abstract

In this investigation we studied how yield-related traits of large-fruited (var. sativum) and small-fruited (var. microcarpum DC.) coriander differ at the Southeastern Bulgaria climatic conditions during 2010-2012. For this purpose, 20 genotypes from var. microcarpum and 20 genotypes from var. sativum were tested using a randomized complete block design with three replications at the Institute of Agriculture – Karnobat. Plant height, number of primary branches per plant, number of umbels per plant, number of fruits per umbel, fruit weight per plant of small-fruited coriander exceeded large-fruited coriander. Large-fruited coriander had higher fruit weight per umbel and 1000-fruits weight. According to variance analyses, the value of the 1000-fruits weight, fruit weight per umbel, fruit weight per plant and number of primary branches were determined by the coriander variety (var. microcarpum DC. or var. sativum) but other characteristics were more affected by the weather conditions of a particular year. Plant height was determined by the environment for both varieties of coriander. Number of primary branches was influenced by the genotype for var. sativum and by the year for var. microcarpum. The influence of the year was greater for the number of umbels per plant, number of fruits per umbel, fruit weight per plant and 1000-fruits weight of var. sativum compared with var. microcarpum.
