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 کاملAbscisic acid enhances resistance to Alternaria solani in tomato seedlings.
The plant hormone abscisic acid (ABA) is an important regulator in many aspects of plant growth and development, as well as stress resistance. Here, we investigated the effects of exogenous ABA application on the interaction between tomato (Solanum lycopersicon L.) and Alternaria solani (early blight). Foliar spraying of 7.58 μM ABA was effective in reducing disease severity in tomato plants. P...
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 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 کاملInheritance of morphological characters and glycoalkaloids in potatoes of somatic hybrids between dihaploid Solanum acauleand tetraploid Solanum tuberosum.
Steroidal glycoalkaloids occur in potatoes and are reported to impart resistance to phytopathogens including bacteria, fungi, and insects. Because glycoalkaloids can be passed to progenies during breeding programs designed to develop improved potatoes, it is of importance to determine the quality of desired characteristics and the composition of glycoalkaloids of new somatic hybrids. The object...
