Novel Germplasm Creation in B rassica nap us by Crucifero us Interspecific Hybridization
摘要
Abstract
In order to broaden the genetic basis of germplasm in Brassica napus ,the feasibility of creating novel germplasm by cruciferous interspecific hybridization was investigated in this article .Results implied that podding ratio and crossing compatibility index differed among different cruciferous species .In both interspecifichybridizationsof BrassicanapusandBrassicajuncea,BrassicarapaandBrassicajuncea,the podding ratios (95.0% and 92.5% ) and crossing compatibility indexes (6.51 and 12.40 ) w ere much higher when Brassica juncea was used as maternal parent than those in reciprocal crosses ,which were 17.5% and 20.0% ,0.56 and 1.12 .In the interspecific hybridization of Brassica napus and Brassica rapa ,the podding ratio(97.5% ) and crossing compatibility index (14.66) when Brassica napus was used as maternal parent were much higher than those of its reciprocal cross ,which were 30.0% and 2.41 , respectively .By interspecific hybridization between Brassica juncea and Brassica napus ,the character of fiddle-shaped leaf in Brassica juncea was transferred to Brassica napus ,which was controlled by one pair of recessive gene .In this study ,Brassica napus lines with high olein acid content (83.44% ) and low linolenic acid content (2.14% ) were obtained .These novel germplasms also had low erucic acid and glucosinolate content ,and could be directly used in production .关键词
