Citation: V : 107 ( 3 ) P : 395-405 Year: 2003 Type: ARTICLE | Literature: oryza Field: abstract Doc ID: pub12764581 Accession (PMID): 12764581 | Matching Sentences: [ Sen. 12, subscore: 1.00 ]: The female transmission rates of the alien chromosome varied from 4 . 4 to 35 . 5% , whereas 8 of the 11 MAALs transmitted the alien chromosome through the male gamete , the range being 1 . 7% ( MAAL 10 ) to 11 . 9% ( MAAL 12 ) . Disomic progenies in BC3 and BC4 generations had complete resemblance to the O sativa parent . Of the 2 , 295 disomic BC3F3 progenies , 309 showed introgression for resistance to BPH and 188 each for WBPH and BB resistance . Four plant progenies which were resistant to both BPH and WBPH were also resistant to BB race 2 of the Philippines . Nine of the 34 BC3F1 plants showed introgression for ten allozymes of O latifolia , such as Est5 , Amp1 , Pgi1 , Mdh3 , Pgi2 , Amp3 , Pgd2 , Est9 , Amp2 and Sdh1 , located on 8 of the 12 chromosomes . Alien introgression was also detected for morphological traits such as long awns , earliness , black hull , purple stigma and apiculus . Abnormal plants with many wild-species traits suddenly appeared in normal disomic progenies . These plants showing instability and abnormal segregation behaviour are being investigated for the activation of transposons .
