Characterization of Resistance in a Somatic Hybrid of Solanum bulbocastanum and S. tuberosum, to Meloidogyne chitwoodi.
A somatic hybrid, CBP-233, between resistant Solanum bulbocastanum (SB-22) and susceptible S. tuberosum (R4) was tested for resistance to Meloidogyne chitwoodi race 1. One week after inoculation, only 0.04-0.4% of the initial inoculum (Pi, 5,000 eggs) as second stage-juveniles infected SB-22 and CBP-233 root systems, compared to 2% in R4. After 8 weeks, the number of M. chitwoodi in SB-22 and C...
متن کاملNuclear and cytoplasmic genome composition of Solanum bulbocastanum (+) S. tuberosum somatic hybrids.
Somatic hybrids between the wild incongruent species Solanum bulbocastanum (2n = 2x = 24) and S. tuberosum haploids (2n = 2x = 24) have been characterized for their nuclear and cytoplasmic genome composition. Cytologic observations revealed the recovery of 8 (near-)tetraploid and 3 hexaploid somatic hybrids. Multicolor genomic in situ hybridization (GISH) analysis was carried out to study the g...
متن کاملGlycoalkaloid profile in potato haploids derived from solanum tuberosum-S. bulbocastanum somatic hybrids.
Cultivated and wild potato species synthesize a wide variety of steroidal glycoalkaloids (GA) that may affect either human health or biotic stress resistance. Therefore, GA composition must be a major criterion in the evaluation of breeding products when species genomes are merged and/or manipulated. This work reports the results of GA analysis performed on unique haploid (2n=2x=24) plants obta...
متن کاملRAPD analysis of the interspecific somatic hybrids: Solanum bulbocastanum (+) S. tuberosum.
The diploid Mexican species S. bulbocastanum (blb) was used as a source of late blight resistance in somatic hybridization with the potato (S. tuberosum, tbr) dihaploid H-8105. The produced 2x blb (+) 2x tbr H-8105 somatic hybrids did not retain the blb parent's characteristic high resistance to P. infestans. The revealed aneuploidy of blb (+) tbr H-8105 hybrids indicated a possible loss of ind...
متن کاملRFLP analysis of chromosomal segregation in progeny from an interspecific hexaploid somatic hybrid between Solanum brevidens and Solanum tuberosum.
Segregation of restriction fragment length polymorphism (RFLP) loci was monitored to determine the degree of homeologous pairing and recombination in a hexaploid somatic hybrid, A206, the result of protoplast fusion between Solanum tuberosum (PI 203900, a tetraploid cultivated potato) and Solanum brevidens (PI 218228), a diploid, sexually incompatible, distant relative harboring several traits ...
