Performance of Different Varieties of Spring Field Pea (Pisum sativum L.) under Irrigated and Rainfed Environments in North China

Abstract

Field pea (Pisum sativum L.) is one of the most important pulse crops, and is widely grown in North China. To exploit potential pea varieties suitable for growing in spring planting areas, a set National Regional Trials of Spring Pea Genotype was carried out under irrigated and rainfed environments across seven locations. Grain yield and agronomic traits of fourteen pea cultivars were evaluated. Analysis of variance indicated that the effect of genotype, environments and genotypes × environments interaction was significant (p < 0.01). Results of GGE biplot analysis showed that the first and second principal components accounted for 77.5% and 14.5%, respectively. Genotypes accounted for just 14.7% of the variation in seed yield, while environments accounted for 39.9%, and genotypes × environments interaction accounted for 45.5% of the variation. Investigating the polygon view led to the identification of five superior genotypes and five productivity environments. Superior genotypes and key environments for grain yield were determined using a general linear model. The significant genotypes × environments interaction effects indicated the inconsistent performance of genotypes across the tested environments. Among the tested genotypes, significant differences were observed for grain yield and yield-related traits. The semi-leafless pea variety Longwan 10 was observed the highest yield (3308 kg/ha) over seven locations. Dingwan 12, Dingwan 13, Tongwan 5, Kewan 7 showed higher, stable grain yield than the overall mean of genotypes and check variety Zhongwan 6. The most representative and productivity regions for grain yield of field pea were Yondeng, Qitai, Liaoyang, Dingxi and Tangshan. These findings represent a comprehensive analysis of yield and stability of spring pea varieties and growing locations, which may be useful for national and international pea improvement programs.

Yield Adaptability and Stability in Field Pea Genotypes Using AMMI, GGE, and GYT Biplot Analyses

“…In reality, climate and soil conditions are not the only factors that determine high yield but also ideal management in research stations, including fertili-zation, actual field preparation, sowing and harvesting time, appropriate irrigation, and also the vital factor for high pea yield and production is actual control of weeds, pests, and foliar diseases. These variances in yield may also indicate remarkable GEI between these environments with the results of previously published reports by Yang et al [52]. So, we made more effort to reduce the variances in these factors, like using pesticides for pests and controlling weeds and foliar diseases to estimate the yield be-side the different environments.…”

Garden Peas Production Variation in Relation to Some Biostimulating Substances

“…In relation to the type of culture and the destination of production, different pea varieties were studied to evaluate the relationship between environmental and technological factors, production, quality, sensitivity to stress factors, etc. (Olle et al, 2020;Kumari & Deka, 2021;Yang et al, 2022). This study evaluated the variation of pod and grain production in garden peas, as a relationship between genotype and biostimulating substances, evaluated the interdependence relationship between grain production and pod production, and found models for estimating pea grain production in conditions of statistical certainty.…”
