Host Response to Reniform Nematode Infection in Resistant and Susceptible Gossypium arboreum Accessions
The reniform nematode (RN), Rotylenchulus reniformis Lindford and Oliveira, is a serious threat to cotton production. In fields infested with RN, yield losses are estimated at 0 to kg/ha (Robinson, 001). Genetic resistance to RN has not been reported for any commercial cultivar of cotton (Gossypium hirsutum L.) (Robinson et al., 00 ); however, it has been found in G. arboreum (Stewart and Robbi...
متن کاملGossypium Lines Resistant to Rotylenchulus reniformis Vary in Sensitivity to the Herbicide Fluometuron
Reniform nematode (Rotylenchulus reniformis) resistance is being transferred to Gossypium hirsutum from its distant relatives. Reports of fluometuron damage to LONREN lines with nematode resistance from G. longicalyx raised concerns about introducing herbicide sensitivity from other nematode resistance sources. The research objective was to evaluate 15 sources of reniform nematode resistance fo...
متن کاملIntrogression of resistance to reniform nematode (Rotylenchulus reniformis) into upland cotton (Gossypium hirsutum) from Gossypium arboreum and a G. hirsutum/Gossypium aridum bridging line
Gossypium hirsutum L. is the predominant cotton of commerce and all cultivars of this species are susceptible to the reniform nematode, Rotylenchulus reniformis. To introgress resistance to R. reniformis into the tetraploid 2(AD1) G. hirsutum, a resistant diploid A2-genome Gossypium arboreum accession (A2190) was crossed with a hexaploid 2((AD1)D4) bridging line (G 371) to obtain a tetraploid t...
متن کاملResistance to Meloidogyne incognita Race 3 and Rotylenchulus reniformis in Wild Accessions of Gossypium hirsutum and G. barbadense from Mexico.
Forty-six accessions of G. hirsutum and two of G. barbadense were examined for resistance to Meloidogyne incognita race 3 and Rotylenchulus reniformis in environmental growth chamber experiments, with the objective of finding new sources of resistance. Only the G. barbadense accessions, TX-1347 and TX-1348, supported significantly less reproduction by R. reniformis than the susceptible control,...
متن کاملGenetic diversity and relationship analysis of Gossypium arboreum accessions.
Simple sequence repeat techniques were used to identify the genetic diversity of 101 Gossypium arboreum accessions collected from India, Vietnam, and the southwest of China (Guizhou, Guangxi, and Yunnan provinces). Twenty-six pairs of SSR primers produced a total of 103 polymorphic loci with an average of 3.96 polymorphic loci per primer. The average of the effective number of alleles, Nei's ge...
