| Abstract: | Interspecific hybrids were obtained in an otherwise incompatible cross Brassica juncea x Brassica tournefortii through in vitro culture of hybrid embryos. The best response was observed from culture of embryos excised 20 days after pollination on MS medium supplemented with kinetin, α-naphthylacetic acid, gibberellic acid, glutamine and casein hydrolysate. One hybrid plant had many distinct or intermediate characters. It was tolerant to aphid attack, exhibited irregularities in meiotic events and was partially fertile. The F2 open pollinated and BC1 progenies showed a large diversity in their morphological traits and some promising plants with less aphid infection, drought tolerance and high yield were selected. |
