“…The other traits, which showed a higher difference between PCV and GCV, indicated that the environmental effect on the expression of those traits is higher and that selection based on phenotypic performance of these traits is not effective for further yield improvement. The finding of Gixhari et al (2014), Ouafi et al (2016), Yumkhaibam et al (2019) and Gupta et al (2020) were similar to the present findings.…”

“…This indicates that a negligible role was played by the environmental factors in the inheritance of these traits in pea genotypes. The high genotypic variance for most of these traits was also reported by other researchers (Gixhari et al, 2014;Ouafi et al, 2016;Gupta et al, 2020).…”

“…Our study revealed that the PCV was higher than the GCV for all studied traits. This was also the case for all the traits observed in previous studies (Gudadinni et al, 2017;Gupta et al, 2020), which reported that the environmental effect on any trait is indicated by the magnitude of the differences between the genotypic and phenotypic coefficients of variation; large differences reflect a large environmental effect, whereas small differences reveal a high genetic influence.…”

“…In this investigation, 15 diverse genotypes of pea obtained from different sources were studied to assess their genetic potential for agro-morphological traits. The combined analysis of variance due to genotype was highly significant for all studied traits, thereby suggesting the presence of considerable amount of variability among tested genotypes and this variability can be further utilized in the pea improvement program by selecting superior and desired genotypes (Gupta et al, 2020). These results in concordance with the works of Dagla et al (2013), Kumar et al (2013), Gixhari et al (2014), Ouafi et al (2016), , and Gupta et al (2020) who analyzed genetic diversity among different genotypes of pea using the same agro-morphological traits and found significant differences.…”

“…Environmental factors are more effects on yield than their components, so selection for these components can be helpful to obtain genotypes with superior yield abilities (Gatti et al, 2005). Genotypic coefficient variation, phenotypic coefficient variation and heritability proffer indication for genetic control for the expression of an assigned trait and phenotypic accuracy to prophesy its breeding value (Ullah et al, 2012;Gupta et al, 2020).…”

Fifteen pea (Pisum sativum L.) genotypes were evaluated for their agro-morphological performance and molecular diversity during 2017-2018 and 2018-2019 seasons. Combined analysis of variance revealed that there are highly significant differences among pea genotypes tested for all agro-morphological traits studied. The phenotypic coefficients of variation (PCV) values were relatively greater than Genotypic coefficients of variation (GCV) for all traits; however, GCV values were near to PCV values for the traits, like plant height, pods/plant, 100 seeds weight and pod width. High heritability coupled with high genetic advance was obtained for, plant height, reflecting the presence of additive gene action for the expression of this trait. High to moderate heritability coupled with moderate genetic gain were exhibited for number of pods per plant, 100 seeds weight, pod length, seeds per pod, pod weight and number of branches per plant. The Euclidean Distance among all genotypes based on agro-morphological traits was relatively wide. ISSR and SRAP markers were used to study the molecular diversity among pea genotypes. The molecular marker parameters revealed that SRAP markers were more efficient than ISSR markers with regards to polymorphism detection and in distinction among pea genotypes. Also, both ISSR and SRAP markers were able to amplify unique bands specific to a particular genotype. A positive and significant correlation (r=0.389: p ≤ 0.001) between ISSR and SRAP matrix was observed according to Mantel's test. Also, significant correlation (r = 0.411: p ≤ 0.001) between the matrices of combined molecular markers data and agro-morphological data.

Drought is increasingly frequent in the context of climate change and is considered a major constraint for crop yield. Water scarcity can impair growth, disturb plant water relations and reduce water use efficiency. Pea (Pisum sativum) is a temperate grain legume rich in protein, fibre, micronutrients and bioactive compounds that can benefit human health. In reducing pea yield because of drought, the intensity and duration of stress are critical. This review describes several drought resistance mechanisms in pea based on morphology, physiology and biochemical changes during/after the water deficit period. Drought tolerance of pea can be managed by adopting strategies such as screening, breeding and marker‐assisted selection. Therefore, various biotechnological approaches have led to the development of drought‐tolerant pea cultivars. Finally, the main objective of the current research is to point out some useful traits for drought tolerance in peas and also, mention the methods that can be useful for future studies and breeding programmes.

Background: Garden pea (Pisum sativum L. var. hortense) belongs to family leguminosae is an important legume vegetable grown throughout the world during cool season. It is self pollinated pulse crop with chromosome number 2n = 2x = 14. Based on genetic diversity its primary centre of origin is Mediterranean region. It is used as fresh vegetable and processed frozen vegetable in India and abroad. It is good source of vegetarian protein (6.8%-7.2%) which is consumed as green seed. The experiment was carried out to estimate the GCA effect of parents and SCA effect of 28 hybrids for green pod yield and its related traits using eight parents in crossing programme. Methods: In this experiment crosses was made in 2018-2019 using diallel mating design (excluding reciprocal crosses) and the data investigated in 2019-2020 at Vegetable Research Farm of C.S. Azad University of Agriculture and Technolgy, Kanpur. Result: In our investigation combining ability analysis revealed significant GCA and SCA for all characters. On the basis of gca effect of parents AP1, KS111, KS282 were good general combiners. Based on SCA effect crosses KS282 x Kashi Nandani, KS280 x Kashi Nandani, AP3 x KS282 were good specific combination for pod yield per plant. Such crosses could be further exploited to obtain transgressive segregants in future breeding programme.
