Genetic variability in quantitative traits of field pea (Pisum sativum L.) genotypes

Abstract

The field pea is very important when it comes to the nutrition of domestic animals, due to a high content of proteins in its grains and aboveground biomass. The aim of this study was to examine genetic variability in quantitative traits of newly created field pea hybrids. The researchers studied two cultivars, one line and their F<sub>3</sub> and F<sub>4</sub> hybrids. The following quantitative traits were analysed: number of pods per plant, number of grains per pod, 1000 seed weight and grain yield. The largest number of pods per plant was recorded for the Baccara × L-CC line hybrid, with a statistically significantly larger (P < 0.01) number of pods per plant than all the other investigated genotypes, lines and hybrids. L-CC line × Baccara, and Saša × L-CC line had a significantly larger (P < 0.05) number of grains per pod. The smallest number of grains per pod was recorded for the Saša and Baccara × Saša hybrid. The genotype vs. year interaction had a significant (P < 0.05) influence on 1000 seed weight. Significantly higher (P < 0.05) 1000 seed weight was recorded for the Baccara genotype, when compared with all other investigated genotypes, lines and hybrids. The lowest 1000 seed weight was recorded for the L-CC line. The genotype × year interaction had a significant influence on the seed yield of field pea. During this research, high seed yields were achieved by the Baccara genotype and Baccara × L-CC line and Baccara × Saša hybrids.

Evaluation of Growth and Yield Characters of Garden Pea Genotypes at Dailekh, Mid-Western Nepal

“…The mean square due to genotype was significant in green pod number/ plant. The number of pod/plant is a variable trait and this result is in agreement with the results of Lakic et al (2017).Genotypes showed the significant variation in green pod yield/plant which indicates differential response of genotypes of this character. Similar results were reported by previous researchers (Chadha et al, 2010;Khichi et al, 2017;Poudel et al, 2017).…”

“…Genetic variability is a prerequisite for any crop improvement programs. Several variability studies have been carried out for various pulse crops such as faba bean, Field pea species [14][15][16][17]. Phenotypic and genotypic coefficients of variation and heritability were commonly used genetic parameters.…”

“…Meteorological conditions are highly variable and unpredictable and greatly affect stability and yield (POPOVIĆ et al, 2012;JANKOVIĆ et al, 2018;LAKIĆ et al, 2019;TERZIĆ et al, 2019;POPOVIĆ et al, 2020a;2020b;JOVANOVIĆ-TODOROVIĆ et al, 2020;PERIĆ et al, 2021). The data of the Republic Hydrometeorological Institute of the Republic of Srpska was used for the analysis of weather conditions.…”
