AFLP analysis of genetic relationships among papaya and its wild relatives (Caricaceae) from EcuadorTheoretical and Applied Genetics - Tập 105 - Trang 289-297 - 2002

The AFLP technique was used to assess the genetic relationships among the cultivated papaya (Carica papaya L.) and related species native to Ecuador. Genetic distances based on AFLP data were estimated for 95 accessions belonging to three genera including C. papaya, at least eight Vasconcella species and two Jacaratia species. Cluster analysis using different methods and principal co-ordinate anal...... hiện toàn bộ

QTL mapping for resistance to root-knot nematodes in the M-120 RNR Upland cotton line (Gossypium hirsutum L.) of the Auburn 623 RNR sourceTheoretical and Applied Genetics - Tập 113 - Trang 1539-1549 - 2006

Root-knot nematodes Meloidogyne incognita (Kofoid and White) can cause severe yield loss in cotton (Gossypium hirsutum L.). The objectives of this study were to determine the inheritance and genomic location of genes conferring root-knot nematode resistance in M-120 RNR, a highly resistant G. hirsutum line with the Auburn 623 RNR source of resistance. Utilizing two interspecific F2 populations dev...... hiện toàn bộ
Mapping of a novel QTL for resistance to cereal cyst nematode in wheatTheoretical and Applied Genetics - Tập 112 - Trang 1480-1486 - 2006

Cereal cyst nematode (CCN; Heterodera avenae Woll.) is a root pathogen of cereals that can cause severe yield losses in intolerant wheat cultivars. Loci for resistance to CCN, measured by a seedling bioassay, were identified by creating a genetic map based on a Trident/Molineux doubled haploid population of 182 lines. A novel locus accounting for up to 14% of the resistance to CCN was mapped to ch...... hiện toàn bộ
Selection of a high and stable pigment-producing strain in cultured Euphorbia millii cellsTheoretical and Applied Genetics - Tập 61 - Trang 113-116 - 1982
Y. Yamamoto, R. Mizuguchi, Y. Yamada
A high pigment-producing strain of cultured Euphorbia millii cells was isolated by clonal selection. The pigment obtained was red and consisted mainly of anthocyanin. The amount of this pigment obtained after 24 selections was seven times that found in the original cells. Statistical and cell-pedigree analyses proved that this cell strain has stable productivity for this red pigment.
