Abstract

This work evaluated the behavior of coriander half-sib progenies ( Coriandrum sativum L.) regarding their agronomic traits. The study was developed in a greenhouse in the Universidade Federal Rural de Pernambuco, PE, Brazil. The experiment was designed as augmented block design with 26 coriander genotypes, of which 24 were coriander half-sib treatments, and two control treatments, ‘Verdao’ and ‘Tabocas’. These progenies were selected from four cycles of phenotypic recurrent selection from the ‘Verdao’ population, which were selected for later bolting. Plant height and canopy diameter were evaluated in the field, and shoot fresh mass. There were significant differences between the treatment means for all variables analyzed. Regarding analysis of variance and SNK test, there is available variability to select half-sib progenies. Genotypes C 4 -014, C 4 -015, C 4 -016, and C 4 -018 had promising productivity compared to the commercial control varieties. The broad-sense heritability values were 77.3, 81.5 and 95.8% for canopy diameter, shoot fresh mass, and plant height, respectively. This result showed that the majority of phenotypic variance is genetic. Therefore, these genotypes may be used in coriander breeding programs of recurrent selection to obtain cultivars adapted to tropical conditions.

Highlights

Horticulture has innovated in several aspects and established its importance by improving land use, encouraging crop diversification and providing healthy food to the population (BISOGNIN et al, 2011).Coriander, Coriandrum sativum L., has been a major component of horticulture in Brazil and worldwide
These results show that the maximum height values obtained in the present study are within the expected range, and the great genetic potential of these four treatments, C4-014, C4-015, C4-016 and C4-018
The genotypes C4-014, C4-015, C4-016 and C4-018 can be selected to obtain a new population with high frequency of favorable alleles to shoot fresh mass

Summary

Introduction

Coriandrum sativum L., has been a major component of horticulture in Brazil and worldwide. It originated in Europe, where it has been cultivated for more than 3,000 years. Its leaves and fruits are highly consumed especially as condiment (NASCIMENTO; PEREIRA 2005). In Brazil, it is the second most important leaf vegetable next to lettuce and is cultivated during the entire year. It is consumed mainly in the North and Northeast regions, but it is currently expanding to Center-Southern Brazil (BERTINI et al, 2010; LUZ et al, 2012)
