Sources of variation for sustainable field pea breeding

Abstract

The pea crop (Pisum sativum L.) is a convenient source of plant protein for animal feeding. The objective of this research was to evaluate field pea breeding lines for agronomic performance and seed quality focussed to their use in a sustainable production. Thirty-five field pea breeding lines and six elite cultivars were evaluated for their agronomic value in field in Spain upon 20 traits related to flower, cycle, plant architecture, productivity and seed quality. The lines showed significant differences in all the quantitative traits evaluated and three of them, namely MB-0307, MB-0308, and MB-0319 were chosen to be evaluated, together with the advanced cultivar ZP-1233, in field and in growing chamber for agronomic performance, seed quality and ability for sustainable production. The four accessions displayed high seed protein content that had significant effect of cropping density with averages of 253.6 g kg -1 under low cropping density of 60 plants m -2 and 259.1 g kg -1 under high cropping density of 90 plants m -2 , therefore, the low cropping density should be regarded as the most convenient. Average yield of the lines MB-0307, MB-0308 and MB-0319 and the cultivar ZP-1233 was fair (197.5 g m -2 ), probably due to the absence of fertilizers and irrigation, aiming for the sustainability of the crop. Intercropping with rye and herbicide application resulted in no differences on the seed yield; therefore, the ability of the breeding lines to grow without herbicide seems to be demonstrated, while the germination of the seeds at low temperature was very good. These results indicate that field pea could be a new protein crop in the North of Spain to satisfy the demand of plant protein for animal feed, based upon adapted breeding lines that combine the ability for growing under sustainable conditions with other desirable agronomic traits maintaining an adequate productivity.

Evaluation of morphological diversity of field pea [Pisum sativum subsp.arvense (L.)] germplasm under sub-tropical climate of Manipur

“…Field pea is an important annual, cool-season pulse crop and dry pea seeds contain high levels of the essential amino acids like lysine and tryptophan, which are deficit in cereal grains (Ana Paula Rodino et al, 2009). Being an important protein source, there is increase in demand for this pulse crop both for animal feed as well as for human consumption (Santalla et al, 2001).…”

Methane emissions from reproductive organs of pea plants exposed to multiple abiotic factors

“…de Sousa-Majer et al (2004) found that water deficiency in pea plants significantly reduced the number of seeds produced by plants; it also decreased the mass of pods. This indicates that water stress has substantial effects on the vegetative and reproductive parts of pea plants ( Rodiño et al 2009).…”

Genotype-specific Patterns of Physiological, Photosynthetic, and Biochemical Responses in Faba Bean Contrasting Pair to Salinity

“…While the hardiest European cultivars may withstand winter temperatures as low as −15°C, harder cultivars growing in the Mediterranean region can withstand winter temperatures as low as −10°C [9]. Due to its high protein content, which can range from 20 to 41% depending on variety, faba bean seeds are particularly essential crops [10]. Additionally, they have enough amounts of both carbohydrates and oil, which raises their nutritional value [10].…”
