Genetic diversity and evolution ofBrassicagenetic resources: from morphology to novel genomic technologies – a review

Abstract

Brassica species have an economic and medicinal importance. Estimation of the amount and distribution of genetic diversity within Brassica species is essential for establishing efficient management, conservation and breeding practices. This review discusses the taxonomy, gene pool, and Brassica-derived phytochemicals and their nutraceutical importance. It also surveys the recently advanced studies of the genetic diversity and phylogenetic studies of Brassica species at the level of morphological, cytological, biochemical and molecular markers that have proven to be useful for evaluating the genetic variation, taxonomic relationships and species identity, and could be useful for improving Brassica crops through future promising breeding programmes.

Genetic Diversity and Combining Ability of White Maize Inbred Lines under Different Plant Densities

“…Assessing the genetic diversity is essential for enhancing the yield and conservation strategies of main crops [ 65 , 66 , 67 , 68 , 69 , 70 ], such as maize that has high an economic importance [ 71 ]. The average genetic diversity existing among all the inbred lines was relatively high (0.61).…”

Introductory Chapter: Assessment and Conservation of Genetic Diversity in Plant Species

“…In conclusion, morphological, cytological, biochemical, and molecular markers proved useful in assessing genetic diversity levels in different plant species [22][23][24][25][26][27][28][29][30].…”

Introductory Chapter: Hormonal Regulation in Plant Development and Stress Tolerance

“…GA is also included in the hormonal crosstalk in environmental signals [47]. In conclusion, like the potential use of molecular and genetic markers in crop improvement [48][49][50][51][52][53][54][55][56][57], phytohormones play crucial roles in development and stress tolerance of crops.…”
