“…According to Chrungu et al (1999), pollen grains from B. maurorum could not germinate on the stigmas of crop brassicas or the pollen-tube could not reach the ovary. As described by Garg et al (2007), the reciprocal cross B. rapa 9 B. maurorum also failed.…”

“…In earlier hybridizations between B. maurorum and Brassica cultivated species (Takahata and Hinata 1983;Prakash et al 1982;Chrungu et al 1999;Garg et al 2007), B. maurorum was used as the female. According to Chrungu et al (1999), pollen grains from B. maurorum could not germinate on the stigmas of crop brassicas or the pollen-tube could not reach the ovary.…”

“…To date, many wild Brassica species have been recognized to possess various resistant characters which are valuable for crop breeding, for example, Brassica spinescens has the resistance to white rust (Kirti et al 1991), Brassica tournefortii resists or tolerate aphids (Liphaphis erismi) and pathogens such as Albugo candida (Choudhary et al 2000). Brassica maurorum (MM, 2n = 16) is resistant to white rust and Alternaria blight (Chrungu et al 1999).…”

The wild species Brassica maurorum Durieu (MM, 2n = 16) is useful for the improvement of Brassica crops. Herein, interspecific reciprocal crosses between B. maurorum and three cultivated Brassica allotetraploids were carried out with the aid of embryo rescue. Trigenomic hybrids with Brassica napus (AACC, 2n = 38) and Brassica carinata (BBCC, 2n = 34) were produced from reciprocal crosses, but the hybrids with Brassica juncea (AABB, 2n = 36) were obtained only when B. maurorum was used as female. All the hybrids were morphologically intermediate between their parents, and were male and female sterile. By in vitro chromosome doubling of the trigenomic hybrids, the allohexaploids (AACC.MM/MM.AACC, 2n = 54; BBCC.MM, 2n = 50; MM.AABB, 2n = 52) were established and characterized for their phenotype and cytology. The fertilities of three allohexaploids were different, for AACC.MM and MM.AACC failed to produce seeds by selfing, but BBCC.MM showed low seed-set and MM.AABB had good seed-set. They also expressed variable extents of male meiotic regularity as to chromosome pairing and segregation, with MM.AABB > BBCC.MM > AACC.MM/MM.AACC, the same order as their fertility. So their meiotic behavior contributed to the fertility. Finally, the potential of these allohexaploids as a bridge for genetic improvement of Brassica crops was discussed.

“…Sources of resistance to the disease have been identified in wild and related species of Brassicas. For instance, Sinapis alba, commonly known as white mustard (Hansen and Earle, 1997), Camelina sativa, Eruca sativa (Tewari and Conn, 1993), Diplotaxis species (Sharma et al, 2002) and B. maurorum (Chrungu et al, 1999). Dang et al, (2000) Rahman et al, (2010) found varying degree of disease severity while evaluating 26 lines of rapeseed-mustard during the extensive research on Alternaria blight at RARS, Jamalpur.…”

“…Some of the more recent ones are B. maurorum (Chrungu et al, 1999), Orychophragmus violaceus (Li and Heneen, 1999), Sinapis arvensis (Snowden et al, 2000), B. tournefortii (Choudhary and Joshi, 2001), and Diplotaxis siifolia (Ahuja et al, 2003). In all cases where the gene required is not on the 'a' genome, or alternatively on the 'c' genome for B. napus, translocation onto the native genome is necessary.…”
