“…Landraces of vegetable crops are recalling an increasing interest, as they are assumed to be tastier and healthier than commercial varieties (Mou, 2005;Rodríguez-Burruezo et al, 2005). Here we have shown that eggplant landraces contain, on average, greater amounts of phenolics, P, and K than commercial varieties.…”

“…The narrow genetic base of most crops, combined with selection for performance under optimal conditions, has reduced the genetic variability in environmental stress responses, and the modern cultivars of tomato are no exception (Bai & Lindhout, ; Bauchet & Causse, ; Bergougnoux ) . The wild relatives of tomato have the genetic ability to adapt to extreme habitats, and many heirloom cultivars also retain this ability as a result of directed breeding with wild species, and less selection for commercially valuable traits (Sim et al , ; Lin et al , ; Blanca et al , ; RodrÍGuez‐Burruezo et al , ) . Heirloom tomatoes are defined as varieties, which have been passed down through multiple generations of a family (Tomato Fest, https://www.tomatofest.com/what-is-heirloom-tomato.html).…”

Summary Commercial tomato (Solanum lycopersicum) is one of the most widely grown vegetable crops worldwide. Heirloom tomatoes retain extensive genetic diversity and a considerable range of fruit quality and leaf morphological traits. Here the role of leaf morphology was investigated for its impact on fruit quality. Heirloom cultivars were grown in field conditions, and BRIX by yield (BY) and other traits were measured over a 14‐wk period. The complex relationships among these morphological and physiological traits were evaluated using partial least‐squares path modeling, and a consensus model was developed. Photosynthesis contributed strongly to vegetative biomass and sugar content of fruits but had a negative impact on yield. Conversely leaf shape, specifically rounder leaves, had a strong positive impact on both fruit sugar content and yield. Cultivars such as Stupice and Glacier, with very round leaves, had the highest performance in both fruit sugar and yield. Our model accurately predicted BY for two commercial cultivars using leaf shape data as input. This study revealed the importance of leaf shape to fruit quality in tomato, with rounder leaves having significantly improved fruit quality. This correlation was maintained across a range of diverse genetic backgrounds and shows the importance of leaf morphology in tomato crop improvement.

“…Many modern varieties have lost most of their genetic diversity within populations and are genetically homogenous compared to their wild relatives (Lam et al, 2010). A certain degree of genetic diversity remains in open-pollinated crops, heirloom varieties, landraces, and crops that have only been weakly domesticated (Reif et al, 2005;RodrÍGuez-Burruezo, Prohens, RosellÓ, & Nuez, 2005). For cultivation of such "primitive" crops, genotype-aggregated planting of seedlings may be effective for increasing yield.…”

Accumulating evidence indicates that plants are capable of self/non‐self and kin/stranger discrimination. Plants increase biomass of and resource allocation to roots when they encounter roots of conspecific non‐self‐neighbors, but not when they encounter self roots. Root proliferation usually occurs at the expense of reproductive investment. Therefore, if clonal crops are capable of self/non‐self‐discrimination, spatially aggregated planting with seedlings of the same genotype may decrease root proliferation and produce a higher yield than planting without considering seedling genotype. To test this idea, we grew Helianthus tuberosus (Jerusalem artichoke) in pot and field conditions and examined self/non‐self‐discrimination and the effectiveness of genotype‐aggregated planting. Plants grown in self pairs allocated less to root biomass than plants grown in non‐self pairs in both pot and field conditions; in field conditions, the self pairs produced 40% more tubers by weight than the non‐self pairs. When six sprouts from seed tuber of two different genotypes were grown together, with the two genotypes planted aggregately (AGG) or alternately (ALT), plants in the AGG group produced 14% more tubers than plants in the ALT group. These results suggest that spatial aggregation of genotypes increases tuber production in H. tuberosus . Because we found no evidence for trade‐offs between root biomass and tuber production, suppression of root proliferation may not be the only mechanism behind the benefits of genotype aggregation. By applying the concept of self/non‐self‐discrimination, farmers can increase crop production without additional external inputs or expansion of agricultural land use.
