Abstract
Obtaining okra hybrids through partial diallel analysis
Highlights
Okra is widely cultivated for its immature fruits that are consumed in different types of preparations
This study aims to identify promising hybrids by estimating the general and specific combining abilities, and to compare the experimental hybrids with commercial cultivars
The climate of the region is Cwa according to Köppen classification, which is subtropical with dry winter and rainy summer
Summary
Okra is widely cultivated for its immature fruits that are consumed in different types of preparations. Most okra production occurs in Asian and African countries, which are socioeconomically vulnerable This implies two important aspects: okra is important for food security in producing countries, and few investments are made to develop modern cultivars and/or more efficient cultural management techniques (Tadele and Assefa 2012). In Brazil, there is no reliable socioeconomic data on okra agribusiness, in the state of São Paulo (IEA 2019), okra yield has not increased compared to other vegetable crops. This can be attributed mainly to the use of open pollinated cultivars and the occurrence of high root-knot nematodes (Silva et al 2019). There is room for introducing more productive cultivars (Chowdhury and Kumar 2019)
