“…Therefore, an appropriate sowing time should be selected for them. Selecting yardlong bean genotypes for photo-insensitivity is also a primary breeding goal [ 200 ]. Regarding soil limiting factors, increasing salinity observed in many areas of Southern European countries [ 201 , 202 ] renders this factor important for cowpea production as for other crops.…”

Cowpea (Vigna unguiculata (L.) Walp.) is a legume with a constant rate of cultivation in Southern European countries. Consumer demand for cowpea worldwide is rising due to its nutritional content, while Europe is constantly attempting to reduce the deficit in the production of pulses and invest in new, healthy food market products. Although the climatic conditions that prevail in Europe are not so harsh in terms of heat and drought as in the tropical climates where cowpea is mainly cultivated, cowpea confronts with a plethora of abiotic and biotic stresses and yield-limiting factors in Southern European countries. In this paper, we summarize the main constraints for cowpea cultivation in Europe and the breeding methods that have been or can be used. A special mention is made of the availability plant genetic resources (PGRs) and their potential for breeding purposes, aiming to promote more sustainable cropping systems as climatic shifts become more frequent and fiercer, and environmental degradation expands worldwide.

“…Long bean ( Vigna unguiculata subsp. sesquipedalis ), also known as Asian yard‐long bean or asparagus bean, is grown traditionally across countries in Southeast Asia (Suma et al., 2021). It is also a popular crop in central California, where it is grown mostly on small‐scale, diversified farms by Southeast Asian refugee Hmong farmers.…”

Long bean (Vigna unguiculata subsp. sesquipedalis, asparagus bean, Asian yardlong bean), the vegetable type of cowpea [Vigna unguiculata (L.) Walp], is a climate‐resilient and nutritious food legume grown by Southeast Asian farmers in the Central Valley of California and marketed to Asian immigrant communities across the United States. Insect pests are major threats, reducing yield and quality of all current lines. Modern plant breeding protocols and extension activities were implemented to develop resistant lines using sources of natural resistance found in African cowpea germplasm. Three aphid‐resistant long bean lines, Dark Green 1994 (Reg no. GP‐320, PI 702995), Light Green 2055 (Reg. no. GP‐321, PI 702996), and Purple 2056 (Reg. no. GP‐322, PI 702997), were developed by introgression of two known quantitative trait loci (QTL) for aphid resistance into three local elite lines through marker‐assisted backcrossing (MABC). One bush‐type long bean line, Bush 2074 (Reg. no. GP‐319, PI 702994), carrying two known QTL for root‐knot nematode resistance, was also developed to enable scaling up production and to improve nematode management in large‐scale commercial farming. These improved lines were evaluated in controlled experiments which also served in outreach activities to enable adoption. Each of these advanced lines, when forming a near‐isogenic pair with its recurrent parent, can provide useful genetic materials for resistance gene discovery.

“…sesquipedalis) is one of the most important legumes cultivated in Cambodia for human consumption (Tantasawat et al, 2010). The plant is known for its resilience to heat and drought stresses and, therefore, finds place in several cropping systems around the world (Suma et al, 2021). It also benefits from rising atmospheric CO 2 concentrations and its fertilization effect, where higher CO 2 concentrations leads to a higher number of pods and seeds, as well as an increase in seed weight over time (Angelotti et al, 2020).…”
