“…Severe chilling injury was also observed in pea accessions from 34 countries at flowering and podding (Shafiq et al 2012). The low-temperature damage in pea resulted in the appearance of aborted buds, flowers and fruit pods and smaller seeds.…”

Of the various environmental stresses that a plant can experience, temperature has the widest and most far-reaching effects on legumes. Temperature extremes, both high (heat stress) and low (cold stress), are injurious to plants at all stages of development, resulting in severe loss of productivity. In response to unfavorable temperatures, plant biomolecules such as stress proteins, enzymatic and non-enzymatic antioxidants, organic osmolytes and phytohormones come into play, usually, as a part of the plant defense mechanisms. The accumulation of these molecules, which may be useful as metabolic indicators of stress tolerance, depend on the plant species exposed to the temperature stress, its intensity and duration. Some of these molecules such as osmolytes, non-enzymatic antioxidants and phytohormones may be supplied exogenously to improve temperature stress tolerance. Legumes show varying degrees of sensitivity to high and low-temperature stresses, which reduces their potential performance at various developmental stages. To address the ever-fluctuating temperature extremes that various legumes are being constantly exposed, efforts are being made to develop tolerant plant varieties via conventional breeding methods as well as more recent molecular breeding techniques. In this review, we describe the progress made towards the adverse effects of abnormal temperatures on various growth stages in legumes and propose appropriate strategies to resolve these effects.

“…Higher stress tolerance has been identified in landrace accessions for toxicity to boron (Bagheri et al 1994), salinity (Leonforte et al 2013) and for iron deficiency (Kabir et al 2012), and new seedling-screening techniques to improve tolerance levels are now being routinely used in Australia (Leonforte et al 2009). There is also preliminary evidence for useful variation for heat stress tolerance during flowering and podding (Petkova et al 2009), and some evidence for higher tolerance to reproductive frost damage based on the yield response of the Australian variety 'Sturt' (Hawthorne 2007) and pod damage (Shafiq et al 2012).…”

The field of plant breeding covers a broad range of different species and categories of plants. While there are many techniques and issues that are similar across these species, many more are unique to each genus.The Handbook of Plant Breeding is organized by major crop categories and includes the most up-to-date molecular techniques being used. It will serve as a resource for plant breeding laboratories in both the university and industrial setting.More information about this series at

“…Although both spring and winter types of field pea are grown in China, most production of pea is in the semi-tropical climate zone as an upland winter crop 17 . However, severe frost damage in winter or early spring that occurs at the seedling stage may cause high rate of seedling death and much production decrease 18 , 19 . Thus, studies on frost tolerance and breeding for winter-hardy cultivars play fundamental roles in the stable increase of pea production 20 – 23 .…”

Frost stress is one of the major abiotic stresses causing seedling death and yield reduction in winter pea. To improve the frost tolerance of pea, field evaluation of frost tolerance was conducted on 672 diverse pea accessions at three locations in Northern China in three growing seasons from 2013 to 2016 and marker-trait association analysis of frost tolerance were performed with 267 informative SSR markers in this study. Sixteen accessions were identified as the most winter-hardy for their ability to survive in all nine field experiments with a mean survival rate of 0.57, ranging from 0.41 to 0.75. Population structure analysis revealed a structured population of two sub-populations plus some admixtures in the 672 accessions. Association analysis detected seven markers that repeatedly had associations with frost tolerance in at least two different environments with two different statistical models. One of the markers is the functional marker EST1109 on LG VI which was predicted to co-localize with a gene involved in the metabolism of glycoproteins in response to chilling stress and may provide a novel mechanism of frost tolerance in pea. These winter-hardy germplasms and frost tolerance associated markers will play a vital role in marker-assisted breeding for winter-hardy pea cultivar.
