“…However, the estimates of narrow sense heritability were low and valued 27.1% (shellout %), 31.8% (seed yield/plant) and 32.9% (100-seeds weight), hereby selection was difficult and should be delayed to later segregating generations. Also, the broad sense heritability was higher for all characters, the line regression between (W\Vr) cut the head line over the original point for all characters (Esho et al, 2012). According to Patel et al (2017), the number of pods per plant and the number of seeds per plant both showed strong heritabilities together with substantial genetic advance, indicating the primacy of additive gene action in the expression of these traits.…”

In tropical climes, the sensitivity of pea (Pisum sativum L.) to high temperatures as well as its underlying genotypic potential with regard to high-temperature ambient/tolerance at field scale remain unknown. The fraction of the hybrids' (F1) means values that increase or decrease relative to those of their best and middle parents is known as heterosis. "Heterobeltiosis" is the term used to describe how an F1 hybrid has improved over its superior parent. The selection of parental genotypes benefits from an understanding of general combining ability (GCA), specific combining ability (SCA), narrow-sense heritability (h2 n.s.), and broad-sense heritability (h2 b.s.). A significant improvement in salinity tolerance may be attainable through selection by the order of high heat stress tolerance values in the pea (Pisum sativum L.). The selection of parental genotypes benefits from an understanding of general combining ability (GCA), specific combining ability (SCA), narrow-sense heritability (h2 n.s.), and broad-sense heritability (h2 b.s.). The Pea (Pisum sativum L.) has high heritability values of the type that confer heat stress resistance, which suggests that a significant improvement in heat stress tolerance may be attainable by selection under conditions of intense selection pressure. Pisum sativum L. characteristics were mostly regulated by the additive and non-additive (dominance) gene activity under both normal conditions and heat stress.

Management for agronomic practices might improves growth and grain yield in pea. The main objective of this experiment was to assess the interacting effects of different irrigation regimes, sowing date and nitrogen fertilizer treatments on pea traits. We evaluated three irrigation regimes (50, 75, and 100% of the plant irrigation requirement), two sowing dates (February and March), and nitrogen [application of nitroregn (N1) and without nitrogen as control (N0)] in 2019 and 2020 under field conditions. Chlorphyll content, leaf area index, leaf water potential, grain yield and water productivity were higher in the late sowing (March) than in early sowing (February) treatment. Percentage of vegetation cover in late sowing (60%) was significantly higher than in early sowing (52.7%) treatment. Grain yield in 75% water requirement treatment was not significantly different from yield in full irrigation treatment. Application of nitrogen fertilizer significantly reduced grain yield, grain protein and seeds per pod whilst increased chlorophyll content only. The 100% irrigation requirement treatment showed higher evaporation form the soil in N0 than in 50% and 75% irrigation treatments in late sown pea. Leaf evapotranspiration (ET) was lower in 50% water requirement irrigation regime than in the other irrigation treatments. Water use efficiency (WUE) which was higher in the late than early sowing treatment did not differ between 50% and full irrigation treatments in N0. In conclusion, the results of the current study suggested that application of nitrogen fertilizer did not benefit pea growth and that management of irrigation regime in late sowing might improve grain yield in pea and save irrigation water in regions with limited water availability.
