Genetic diversity in okra
-
Eclectic variation between Indiana and the rest of the accessions for both agromorpho-economic traits and molecular markers affirms its potential usefulness as a source of diverse genes for future breeding programmes. Sequencing of regions from all accessions, suggests that they are identical with a common ancestry. Outcomes of this study is timely for an ongoing okra hybridisation programme in Ghana.

The present investigation was therefore, undertaken to assess the nature and magnitude of genetic diversity available in the genotypes of okra on the basis of various growth, earliness and yield attributes.

Genetic diversity among sixty three okra genotypes was estimated using Mahalanobis D2 statistic. The genotypes were grouped into nine clusters. The maximum number of genotypes was found in cluster I (36) followed by cluster III (15) and Cluster II (6). Remaining all were solitary clusters with single genotype.

Heterosis is one of the greatest practical achievements of plant breeding and has been extensively used in crop improvement in okra. The production of hybrid cultivars with higher fruit yield and quality characters has become increasingly important in recent years due to continuous demand. In the present study, 14 genetically diverse okra parents were crossed in Line x Tester fashion to explore magnitude of heterosis.

The present study was taken up in the Agricultural College, Bapatla during 2016-2017. Cercospora infected leaves were collected during kharif 2016 from eight different okra growing villages in Guntur district, Andhra Pradesh which were used for in planta isolation of fungal DNA and amplified using universal primers ITS 1 and ITS 4. The 550 bp amplicon thus obtained was restricted with hexa cutters, EcoRI, BamHI and tetra cutter Taq1 to find variability among Cercospora isolates.

Genetic diversity is the first and important parameter in crop improvement programme. In the present investigation fifty okra genotypes were assessed to know the nature and magnitude of genetic divergence by using Mahalanobis D2 statistics.

Genetic divergence of 30 okra genotypes was studied using Mahalanobis D2 statistics revealed that considerable genetic diversity among genotypes in okra. Thirty diverse genotypes were grouped into six clusters with the highest of 11 genotypes in the cluster II, 10 in the cluster I, 4 genotypes in the cluster III, 3 in cluster V and 1 in each IV and VI cluster. The inter cluster distance was higher than the intra cluster distance indicating wide genetic diversity among the genotypes of different groups.

An attempt was made to assess the genetic variability, heritability and genetic advance in okra [Abelmoschus esculentus (L.) Moench] using 31 diverse genotypes; were grown in randomized block design with three replications during kharif 2018 at college farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari, Gujarat (India). Observations were recorded on ten characters showing considerable variability.

The present investigation was carried out at Horticulture Research Station, Dr. Y. S. R Horticultural University, Venkataramannagudem, West Godavari district during kharif season, 2018.Based on D2 values, the twenty-nine hybrids of okra grouped into six clusters. Among the sixclusters, cluster III comprised the maximum number of hybrids (6) followed by cluster II (5), cluster V (5), cluster VI (5), cluster I (4) and cluster IV (4). The maximum inter cluster distance was observed between clusters I and VI (D2 =65.06) followed by clusters II and VI (D2 =62.51).
