Brassica species are vulnerable to narrow genetic base due to the ignorance
of their wild relatives which possess many superior characters. This study
was aimed to explore the genetic diversity in five Brassica species from U
triangle as well as in their wild relative Eruca sativa. For the complete
insight of genetic diversity, four accessions, each from five species of
genus Brassica along with one species of Eruca collected from different
geographical locations (exotic and indigenous) were selected. Six yield
associated parameters viz., primary branches plant-1, plant height, main
raceme length, silique length, silique width and silique main raceme-1 were
studied. Highly significant variations among all species were observed. Mean
performance showed that wild relative E. sativa was superior for primary
branches plant -1 and plant height, which are the main yield associated
traits. In case of Brassica species, B. campestris gave the lengthiest main
racemes, B. nigra produced more silique main raceme-1 and B. carinata
produced the longest and widest silique.
