“…In tomato ( Solanum lycopersicum L.), an economically important vegetable widely grown and consumed in the world, yield and quality traits were found to demonstrate strong G × E 12 – 16 . Concurrent stability studies in yield traits have allowed the separation of population of tomato varieties into highly stable and highly unstable 17 – 20 .…”

Grafting with vigorous rootstocks could offer tomato growers in Texas sustainable and efficient option to achieve reliable yield across a range of production systems and locations. Genotypes (G) of grafted and non-grafted tomato were grown in different environments (E) in the 2017 and 2018 spring seasons. The objectives of the study were to (i) evaluate the effects of production system and grafting on tomato yield traits, (ii) determine the size of genotypic and genotype by environment interaction (G × e) variance components, and (iii) evaluate the relative stability of tested genotypes for yield and its components across production environments. In 2017, genotypes were non-grafted 'TAMU Hot Ty' (TAM) and 'Tycoon' (TY) and each grafted on commercial tomato rootstocks 'Estamino' (TAM/ ES, TY/ES) and 'Multifort' (TAM/MU, TY/MU) while in 2018, TAM and 'HM1823' (HM) were grafted on 'Estamino' (TAM/ES, HM/ES) and 'Multifort' (TAM/MU, HM/MU). Testing environments were high tunnel (HT) and open-field (OF) in Uvalde in 2017 while in 2018, these were HT and OF in Lubbock (LU-HT, LU-OF), Overton (OV-HT, OV-OF), Uvalde (UV-HT, UV-OF), and Weslaco (WE-HT, WE-OF). Total and marketable yields, fruit number per plant, and average fruit weight were significantly affected by E, G, and G × E interaction. Environmental component contributed 71-86% to the total variation for all these traits, while genotype explained 1.5-10.8%, and the contribution of G × E ranged between 4.3 to 6.7%. Estimation of the univariate statistic parameters and genotype plus genotype × environment (GGE) biplot analysis indicated that HM/MU and HM/ES were the most stable graft combination with the highest total and marketable yields, while TAM/ES was very unstable for yields across test environments. TAM/MU was stable but with yield lower than the grand mean. These results suggest that high tomato yields could be consistently achieved with grafted combination (HM/MU and HM/ES) especially under high tunnel production system across the regions of texas. Genetics, environmental factors, and cultural management practices typically determine the extent of quantitative traits of economic importance such as genotype or cultivar yield. As such, the proportion of the variation in this phenotypic trait due to the main effect of genotype (G), the environment (E) and their interactions (G × E) is routinely assessed during the process of selecting top-performing lines 1. In this regard, multilocation trials are routinely conducted to assess the pattern of genotypic response over a number of locations and years (test environments). Typically, a significant G × E exists whenever the genotype performance greatly differs with environments 2,3. When a significant G × E is identified, subsequent stability analysis is often carried out to identify stable genotypes which exhibit consistently higher yield over several environments 4. The presence of significant G × E has been found in growth and yield traits of several field 5-8 and vegetable crops 3,9-11. In tomato (Solanum lyc...

“…There are several naturally occurring mutations with the long-shelf life properties that affect the ripening of fruit, such as Nr (Never Ripe) 5 , alc (alcobaca) 6 which synonymous with the DFD (delayed fruit deterioration) mutation 7 – 9 rin (ripening inhibitor) 10 , nor (non-ripening) 11 and Cnr (colorless non-ripening) 12 , and these genes have been cloned and studied at the molecular level (NM_001246965, FJ404469, NM_001247047, NM_001319308 and NM_001319308). In addition the mutations rin , nor and alc have been used for long-shelf life breeding programs with the heterosis for yield 13 , 14 . Although theses mutations negatively affect organoleptic quality 15 , 16 , alc mutation seems more appropriate than rin and nor in the breeding of long-shelf life varieties with a low negative impact on fruit quality, particularly better skin color, aroma properties and resistance to bacterial disease 9 , 17 .…”

Quickly and precisely gain genetically enhanced breeding elites with value-adding performance traits is desired by the crop breeders all the time. The present of gene editing technologies, especially the CRISPR/Cas9 system with the capacities of efficiency, versatility and multiplexing provides a reasonable expectation towards breeding goals. For exploiting possible application to accelerate the speed of process at breeding by CRISPR/Cas9 technology, in this study, the Agrobacterium tumefaciens-mediated CRISPR/Cas9 system transformation method was used for obtaining tomato ALC gene mutagenesis and replacement, in absence and presence of the homologous repair template. The average mutation frequency (72.73%) and low replacement efficiency (7.69%) were achieved in T0 transgenic plants respectively. None of homozygous mutation was detected in T0 transgenic plants, but one plant carry the heterozygous genes (Cas9/*-ALC/alc) was stably transmitted to T1 generations for segregation and genotyping. Finally, the desired alc homozygous mutants without T-DNA insertion (*/*-alc/alc) in T1 generations were acquired and further confirmed by genotype and phenotype characterization, with highlight of excellent storage performance, thus the recessive homozygous breeding elites with the character of long-shelf life were generated. Our results support that CRISPR/Cas9-induced gene replacement via HDR provides a valuable method for breeding elite innovation in tomato.

“…In north Indian parts, these mutant alleles shows extended fruit availability period by delaying ripening process of fruits on the plant [11; 14]. Heterozygous hybrids from these mutant alleles perform more uniformly in diverse environments as well as in stress condition than homozygous, this property discussed as a 'physiological homeostasis' [15]. Therefore, heterozygous F1 hybrids for these mutant alleles are a key solution to reduce the post-harvest losses and increase fruit availability period to a greater extent than other normal genotypes.…”

An investigation on tomato was conducted at PAU, Ludhiana during 2020-21 with an objective of developing hybrids possessing maximum harvesting span with desirable horticultural traits. Experimental material, comprised of 56 F1 hybrids, 18 parental lines and standard check 'PTH-2', were transplanted in randomized complete block design in three replicates. Evaluation for all the experimental material was carried out during main as well as spring season. Cross combinations viz., PAU 114×nor-RM-1, PAU 2381×nor-RM-1 in main season while, crosses LT-44×rin-Rutgers, PAU 2381×rin-Rutgers in spring season recorded significant heterobeltosis and heterosis over check for yield and quality traits. Out of 56 hybrids, CLN1621L×alc-IIHR-2050, LT-44×rin-Rutgers in main as well as spring season, PAU 2381×nor-RM-1, Leader×nor-RM-1, LT-42×alc-IIHR-2050 and Roma×nor-RM-1 in main season and PAU 2381×rin-Rutgers, FL-556×rin-Rutgers, FL-556×alc-IIHR-2050 and LT-44×alc-IIHR-2050 in spring season were best for prolonged harvesting span vis-à-vis fruit yield, weight, minimum days from transplanting to first harvest, pericarp thickness, lycopene content, dry matter, TSS and titrable acidity. Therefore, the hybrid crosses which expressed higher yield potential in addition with acceptable qualitative performance together with maximum harvesting span could be utilized for commercial exploitation. HIGHLIGHTS• The heteroticpattern for yield and quality traits in tomato were assessed in two environmental conditions.• Simultaneously, ripening genes i.e. rin, nor and alc genes were studied to prolong harvesting span.• Out of 56 tomato hybrids, CLN1621L×alc-IIHR-2050 and LT-44×rin-Rutgers crosses were found best in main and spring season.
