“…Breeding methods have the following roles: creating genetic variations using conventional and biotechnological methods; selecting recombinants with great potential according to performance data, pedigree records, and genetic information; and selecting the appropriate breeding program to create variations (Shashibhushan and Muchanthula 2021). The high-yield trait can be achieved by the interspecific crossing of cultivated tomatoes and commercial hybrid tomatoes that exhibit morphological characteristics related to yield potential (Resende et al 2020).…”

Abstract. Anisa WN, Afifah EN, Murti RH. 2022. Selection of tomato breeding lines based on morphological traits associated with high yield potential in double-cross population. Biodiversitas 23: 2973-2980. Low tomato production is a global problem. Plant breeding has been intensified to develop high-yield varieties and meet the high production of vegetable crops. Selection is an essential part of plant breeding to evaluate desirable traits of breeding lines. This study aimed to identify tomato breeding lines with high yield potential from 13 breeding lines and 2 commercial tomatoes. Collected data were analyzed using analysis of variance, post hoc, path, and principal component analysis. Results showed that 9 tomato lines, namely, BV-1, BV-2, BV-3, BV-6, BV-7, BV-9, BV-11, BV-12, and BV-13 had a high yield potential based on the number of fruits per plant and fruit weight. Given their high path coefficient value and significant correlation (P<0.05) with the yield potential, these two characteristics are highly recommended to be used as selection criteria for the high yield potential of tomato plants. The following characteristics had a high value of heritability: fruit weight, fruit length, fruit diameter, fruit firmness, fruit locules, fruit pericarp thickness, total soluble solid, number of flowers per bunch, number of fruits per bunch, number of fruits per plant, and harvesting age.

“…Spooner var. hirsutum confer resistance to a wide range of pests [6,26] due to the presence of chemical compounds called acylsugars and/or zingiberene (referred to as ZGB throughout the text), present in leaflets, which are exuded by glandular trichomes, mainly of type IV and VI [27][28][29][30][31][32]. These allelochemicals promote resistance because they have deleterious effects on the feeding process and/or life cycle of pests [21].…”

Arthropod pests are among the biggest problems faced in tomato production worldwide. To overcome the losses caused by these pests, one of the most sustainable and economical strategies is the use of resistance introgressed from wild species. We aimed to develop BC3F2 tomato genotypes with high levels of zingiberene (ZGB) and resistance to whitefly (Bemisia tabaci biotype B), South American tomato pinworm (Tuta absoluta), and the two-spotted spider mite (Tatranychus urticae), from the wild accession of Solanum habrochaites var. hirsutum (accession PI127826). The quantification of ZGB in 520 BC3F2 genotypes and in the parentals yielded the selection of five genotypes with high ZGB content and three with low ZGB content, which were then infested with B. tabaci, T. absolute, and T. urticae. In these eight genotypes and in the parents, the types and amounts of trichomes on the leaves were determined. Additionally, molecular markers were used to identify the genotypes with a higher recurrent genome recovery. The results confirmed the transfer of resistance from S. habrochaites to the BC3F2 genotypes and showed that this resistance seems to be directly related to high concentrations of ZGB and the presence of type IV trichomes.

This study aimed to investigate the growth and development parameters of Phthorimaea absoluta (Meyrick) population at each stage when feeding on 4 host plants: Lycopersicon esculentum, Solanum tuberosum, Solanum melongena, and Nicotiana tabacum. The objective was to predict population dynamics and develop appropriate control strategies. The age-stage sex-life table was used to evaluate survival rate, fecundity, life expectancy, reproductive value, population parameters, and population growth prediction of P. absoluta after feeding on the 4 Solanaceae plants. The results showed significant variations in the fecundity parameters of P. absoluta among the different host plants. The L. esculentum population exhibited the highest average egg-laying period (13.17 ± 0.61 days) and average egg production (219.31 ± 21.02 eggs), while N. tabacum had the lowest values (4.56 ± 0.26 days and 26.08 ± 2.53 eggs, respectively). The gross reproduction rate of P. absoluta feeding on L. esculentum was 146.43 ± 21.00, which was 1.80, 3.77, and 6.39 times higher compared to S. tuberosum, S. melongena, and N. tabacum, respectively. The average age period and population doubling time of P. absoluta feeding on L. esculentum were lower than those of the other 3 host plants. These results indicated that while P. absoluta can complete a generation on L. esculentum, S. tuberosum, S. melongena, and N. tabacum, L. esculentum is the most suitable host for its growth and development. Therefore, in the occurrence and adjacent areas of P. absoluta, relevant authorities should promptly monitor and control its population in the planting areas of Solanaceae plants to prevent further spread.
