Evaluation of okra landraces based on agronomic and biochemical traits

Abstract

Okra is consumed in several countries and is an important source of nutrients for human food. To promote okra production and consumption is essential the development of new cultivars with high nutritional levels, besides desirable agronomic traits. Thus, this study aimed to evaluate nine okra landraces by agronomic and biochemical traits. The accessions UEL2, UEL3, UEL5, UEL6, UEL7, UEL9, UEL10, UEL13 and UEL15 were grown in open field condition and evaluated in relation to fruit yield, fruit weight, fruit diameter, number of fruits per plant and plant height. The biochemical analysis included mineral composition, crude protein content, vitamin C content, total flavonoid and phenolic content and antioxidant activity. The UEL7 accession stood out for the high levels for biochemical traits such as content of some minerals, vitamin C and antioxidant activity. On the other hand, UEL3 accession had a low performance for biochemical traits, but stood out for agronomic traits such as fruit yield and number of fruits per plant. Hence, the UEL7 and UEL3 landraces may be introduced in breeding programs focused on human food and agronomic performance, beyond to contribute for okra germplasm conservation.
