“…Normal‐leafed peas showed a more serious yield reduction due to lodging. This circumstance was also recorded by Singh and Srivastava (2015); serious lodging after flowering reduced irradiation to the leaflets on lower internodes of normal‐leafed genotypes. Semi‐leafless peas that stand more upright create better conditions for sunlight to penetrate to the lower part of the plants.…”

Pea (Pisum sativum L.) is a major pulse crop important as feed and food. Due to the symbiosis with N-fixing bacteria, it is a valuable component of low-input cropping systems. The traditional cultivation of peas was limited by their high susceptibility to lodging. This problem was reduced, though not completely solved, by a semi-leafless mutant. Almost all modern cultivars carry this mutant. It is still an open question as to whether the lack of leaflets may have impaired the productivity. In organic farming, there is still interest in normal-leafed peas as they can better compete with weeds. To compare the two leaf types, 24 normal-leafed and 30 semi-leafless genotypes were evaluated in three environments. Semi-leafless genotypes had a higher seed (51%) and straw (40%) yield, but most normal-leafed genotypes were older or less adapted than the semi-leafless ones. Some newer normal-leafed cultivars achieved the same yield level, but their cultivation is only possible in mixtures with a supporting crop. Nitrogen content in seed (10%) and in straw (30%) was lower in semi-leafless genotypes. A negative correlation of yield and N content was observed in both leaf types. However, semi-leafless peas had a higher N yield in seed and in straw. No correlation between N yield in seed and straw was found, so it is possible to combine a high seed yield with a high N yield in the straw. This is particularly important in organic production systems, where peas are also grown to provide N to the following crop.

“…This suggested that these three traits can be advantageously used as a selection criterion to improve yield. Singh and Srivastava (2015) also reported significant correlation between 100 seed weight and seed yield per plant among tall as well as dwarf pea genotypes.…”

An investigation was carried out to evaluate 51 diverse field pea genotypes at Langol Research farm, ICAR, RC, NEH Region, Manipur Centre for nine yield related quantitative traits and four morphological qualitative traits for practical field pea improvement in Manipur. The combined analysis of variance of genotypes for all the nine traits was found to be significant. The amount of variability in one variable as a linear function of another variable was also measured through phenotypic and genotypic correlation among nine quantitative traits. The pod number per plant, seed number per pod and 100 seed weight showed significant positive correlation with seed yield per plant both at phenotypic and genotypic levels. Multivariate analysis using principal component analysis (PCA) indicated that three principal components (PCs) accounted for > 75% of the total variation. The genotypes were grouped into seven clusters using distance based Agglomerative "Average linkage" method. Three genotypes IPF-5-19, EC-8495, HUDP-15 belonging to cluster II and DDR-30, early maturing variety belonging to Cluster VI were found promising in terms of seed yield for the region.

“…Skubisz et al (2007) also concluded that stem wall thickness was correlated with the strength and lodging potential of pea stems. Singh and Srivastava (2015) indicated that days to maturity was positively correlated with lodging susceptibility, and that lodging susceptibility was negatively correlated with seed yield per plant. Kosev and Mikic (2012) found that lodging resistance was negatively correlated with seed size and positively correlated with branch number, pods per plant, seeds per plant, fertile nodes per plant, seeds per pod, seed weight per plant, and branch length.…”

To discover the quantitative trait loci (QTLs) influencing lodging resistance and other agronomic traits in pea (Pisum sativum L.), a recombinant inbred line (RIL) population was created from a cross between the variety Delta and a breeding line from a complex cross. The RIL population was grown for five site years, and phenotypic data were collected for 13 quantitative traits and seven categorical traits. Genotypic data were derived from single nucleotide polymorphism (SNP), simple sequence repeat (SSR), and cleaved amplified polymorphic sequence (CAPS) markers. A layered QTL analysis identified seven specific regions where QTLs for these traits colocated. Mendel's height gene (Le) and the semi‐leafless mutation (Af) together accounted for the majority of the variation in lodging in the pea RIL population. All of the seven regions influenced stem thickness characteristics, but not all regions were associated with lodging. The regions near the high response to photoperiod (Hr) gene, and Mendel's flower color locus (A) putatively influenced yield. Both the region near Hr and a region on upper Linkage Group (LG) I were very important for seed size. Since data were collected on 13 different traits, pleiotropic effects could also be studied, giving a unique multi‐trait insight into the effects of these QTLs.
