“…Suggesting that these characters could be considered as major green pod yield contributing characters in pea. These findings are in line with the reports of earlier researchers Kumar et al (2010) [10] , Ram et al (2010) [10] , Pal and Singh (2012) [16] , Kumar et [3] . These correlations suggest that selection of these component traits will be effective in improving yield of pea.…”

“…Length of pod and average weight of ten pods showed positive and significant correlation with number of seeds per pod. Results are in agreement with the findings of Nawab et al (2008) [15] , Yadav et al (2010) [21] , Pal and Singh (2012) [16] , Kumar et al (2015) [11,12] , Katoch et al (2016) [7] and Devi et al (2017) [3] . Pod yield per plant showed highly significant positive correlation with number of pods per plant and weight of ten pods both at genotypic and phenotypic level.…”

“…Number of pods per plant showed positive significant association with width thickness and shelling per cent. These results are in line with those of Yadav et al (2010) [21] , [6] , Kumar et al (2015) [11,12] , Katoch et al (2016) [7] , Thakur et al (2016) [19] and Devi et al (2017) [3] . Length of pod and average weight of ten pods showed positive and significant correlation with number of seeds per pod.…”

“…Thus, this trait might be reckoned as the most important component trait for pod yield per plant. The results are in propinquity with Sharma et al (2007) [18] , Kumar et al (2010) [10] , Ram et al (2010) [10] , Heena et al (2016) [5] , Devi et al (2017) [3] , Kumawat et al (2018) [13] and Lal et al (2018) [14] whereas days to first picking had the highest negative direct effect on pod yield per plant followed by days to first flowering, number of seeds per pod, thickness of pod and shelling per cent. Hence simultaneous selection for these characters can be made for the improvement of yield.…”

The experiment was conducted in order to estimate the character association for eleven traits in thirty diverse garden pea genotypes during Rabi season of 2018-19 at the Research Farm, Department of Vegetable Science, College of Horticulture, Mudigere. Quantitative analysis were carried out for all the characters which are directly or indirectly associated with the yield and yield contributing traits. The correlation studies revealed that pod yield per plant exhibited highly positive and significant character association with number of pods per plant and weight of ten pods. Therefore, these traits may be considered as the most reliable selection indices for effective improvement in yield.

“…In India too the native honey bees have alarmingly declined in population over the past decades (Chakrabarti 2019; Devi et al 2021). They have become increasingly endangered because of large-field monocropping, chemical intensive agricultural practices, habitat loss due to urbanisation and diseases brought by invasive honey bee species (Fitch et al 2019; Nath et al 2023).…”

Little is known about the agroecological implications of the Asian honey bee Apis cerana Fabricius in its vast native range including southeast India. To identify the foraging preferences of this generalist species, we collected 388 corbicular pollen samples over three years at Merveille, an eco-restoration site in Puducherry region, southeast India. Pollen was collected twice or thrice weekly from March 2018 to December 2021 in three locations within the site. We used canonical correspondence analysis to evaluate how average daily temperature, humidity and other meteorological changes over the years would influence A. cerana's diet. We show that (1) A. cerana has a large dietary niche (87 pollen taxa), but essentially feeds on Cocos nucifera (all year long) and on Borassus flabellifer, Turnera, Acacia, Mollugo/Trianthema, Leucaena/Prosopis, Portulaca, Poaceae, Syzygium-t, Dodonaea viscosa and Boerhavia seasonally; these were most frequently and abundantly foraged at all locations. (2) In all locations, bees preferentially feed on arboreal plants (44 taxa). (3) Bees' pollen diet varies in composition according to seasons. It is also least diverse in the hottest and driest months (March-May) with 2–4 taxa against 7–13 taxa in other months. (4) In 2021, which was more humid and slightly cooler than 2018 and 2019, bee diet included more pollen of Cyperaceae, Dodonaea viscosa, Liliaceae and fallow land weeds such as Boerhavia and Mimosa pudica. In conclusion, corbicular pollen loads of Apis cerana provide a long and continuous record of the bee's diet and its changes through time and space. The diet changed according to subtle changes in humidity and temperature as also drastic changes in rainfall at the study site, likely reflecting changes in the floral resource availability and the bees' preference. The sustained presence of this bee species within its native ranges can be a bellwether of pollinator friendly habitats.

Background: Garden pea is an important leguminous vegetable crop but the lack of high yielding and stable varieties is the major constraint. There is a need to explore genetic variability for the crop improvement programs. Considering this, the current investigation was aimed to study the genetic variability and relationship among the yield and its contributing traits in advanced matromorphic progenies for effective production. Methods: A two year experiment was carried out at SKUAST- Chatha, Jammu during the cropping season of 2020-21 and 2021-22 to find out the genetic variability parameters, path coefficient and correlation studies for thirteen yield contributing traits in twenty two garden pea genotypes (twelve advanced matromorphic progenies and ten parental lines). Result: The results revealed high variability among the tested genotypes. The values of phenotypic coefficient of variation (PCV) were greater as compared to the genotypic coefficient of variation (GCV) for all the traits. High heritability along with genetic advance ( greater than 20%) was observed for all the traits whereas pod length (PL) and shelling percentage (SP) were exceptions. Pod yield per plant ( PYPP) had positive genotypic and phenotypic correlation with node at which first flower appears (NFFA), plant height(PH), internodal distance (ID), no. of pods per node (NPPN), pod length (PL), no. of seeds per pod(NSPP), no. of pods per plant (NPP), days to first picking (DFF), average pod weight (APW) and shelling percentage (SP). Positive direct effect on pod yield per plant (PYPP) was exhibited by traits viz., days to 50 per cent flowering (DFPF), node at which first flower appears (NFFA), internodal distance (ID), no. of pods per node (NPPN), pod width (PW), no. of seeds per pod (NSPP), no. of pods per plant (NPPP), days to first picking (DFP) and average pod weight (APW) in path coefficient analysis.
