“…However, there was close linkage and very minute difference between the values of PCV and GCV with respect to most of the traits except pod width and number of flowering nodes per inflorescence revealing the fact that there was very minor influence of environment on the expression of most of the characters and selection of these characters based on phenotype would be effective. Similar results were disseminated in the findings [3,[17][18][19][20][21][22].…”

Dolichos bean is an indigenous legume grown as vegetable (Lablab purpureus var. typicus) and pulse (Lablab purpureus var. lignosus) throughout India. A wide range of variation exists for the morphological and reproductive characters amongst the land races of Indian Bean grown all over the country. Therefore it is necessary to select variety having desired pod quality with high yield potential. Despite of these good attributing characters it is still regarded as underexploited vegetable because of low productivity, long duration and photosensitivity, flowering irregularity, growth habit and preference of consumers with respect to pod shape, pod size, pod colour, pod aroma. Keeping this in view the present investigation was conducted at All India Co-ordinated Research Project on Vegetable Crops, Odisha University Of Agriculture and Technology, Bhubaneswar during Rabi, 2020-21 for evaluating the yield and yield attributing characters, for estimating the variability, heritability, genetic advance and the association between yield and yield attributing characters for an effective selection to estimate the genetic variability in Dolichus bean [Lablab purpureus (L.) sweet var. typicus] genotypes for further crop improvement study. The genotypic variance ranged from 0.02 for pod weight per plant to 2435 for average leaf area. The phenotypic variance ranged from 0.023 for pod weight per plant to 2879.8 for average leaf area. Phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (PCV) for all the 14 characters taken. This happened because PCV estimates includes variations due to environment (E) and genotype and environment (GE) interaction. PCV was highest (60.31) for pod yield per plant followed by average leaf area (35.09) indicating the presence of wide range of genetic variability in the germplasm for these traits. Higher value of GCV was found for characters like pod yield per plant (59.80) followed by average leaf area (32.26) and number of pods per plant (31.94). Highest estimates of heritability in broad sense was observed in Pod weight per plant (98.30) followed by number of pods per plant (96.17), average leaf area (84.55), number of pods per inflorescence (83.91), pod length (82.22), plant height (78.82), pod yield per hectare (78.66) indicating that these characters are less influenced by environment.

“…While, low GCV and PCV values were recorded for days to 50 per cent flowering(3.42 % and 4.16 %, respectively), days to maturity (2.27 % and 2.94 %, respectively), pod length (7.99 % and 9.78 %, respectively), pod width (8.75 % and 9.36 %, respectively) and seeds per pod (2.62 % and 3.07 %, respectively) except plant height (8.24 % and 10.43 %, respectively) which showed moderate PCV value suggesting a limited range of variability for these traits and limited scope of selection for them. Similar results were also obtained for seed yield per plant byPeer et al (2018); for pods per raceme bySingh et al (2011); for racemes per plant and days to 50 per cent flowering byPatel et al (2022); for pods per plant and pod weight byAfsan and Roy (2020); for seeds per pod and pod length byGnanesh et al (2006) and for days to maturity byPatel et al (2022). pod length, pod width and seed yield per plant byHadavani et al (2018); for plant height and pods per raceme byMagalingam et al (2013) and for seeds per pod byPeer et al (2018).In the present study, high genetic advance as per cent of mean was observed for racemes per plant (23.73 %), pods per plant (20.95 %), pod weight (21.31 %) and seed yield per plant (44.86 %) (Table2).…”

The experiment was carried out to determine the genetic variability parameters and character associations for eleven quantitative traits in Indian bean genotypes. It revealed a significant amount of variability present among these genotypes. Seed yield per plant had high Genotypic coefficient of variation (GCV) and Phenotypic coefficient of variation (PCV) values, showing the potential for improvement by selection. Racemes per plant, pods per raceme, pods per plant, and pod weight had moderate GCV and PCV values. There was high heritability combined with a high genetic advance for pod weight and seed yield per plant. Plant height, pods per plant, and pod weight were significantly and positively associated with seed yield per plant. Pods per plant had the most positive direct effect on seed yield per plant, followed by racemes per plant, plant height, pod weight, pod length, and seeds per pod. Therefore, selection for such traits is advised to bring about improvement in Indian beans.

This study was conducted evaluate the performance of Lablab genotypes across various locations of Ethiopia. Twelve accessions of L. purpureus obtained from ILRI Genebank and a check registered variety from Bako Agricultural Research Center were sown under a 3 × 13 factorial experiment in a randomized complete block design (RCBD) during the rainy season in 2020, across three locations, namely Tepi, Bechi, and Kite sites of South West Ethiopia. The data were collected on the establishment, days to different physiological stages, forage yields, soil properties, and other related parameters. The data were subjected to analysis of variance using the general linear model of SAS and mean comparison via list significance difference test. A significant difference ( p ≤ 0.01 ) was observed across locations for most of the studied agronomic traits. The highest average dry matter (DM) forage yield recorded for T6 (accession 11613), T8 (acc. 10953), T5 (acc. 14417), and T4 (accession 11612) was 10.3, 8.7, 6.8, and 7.4 t/ha-1, respectively. Dry matter forage yield was positively associated and regressed with plant height and leaf-to-stem ratio. Lablab accessions are well adapted to the ecology tested. Lablab could also be produced in these locations without any remarkable disease problems. It is recommended that five top forage producing accessions be advanced for the next step of yield evaluation in standard multilocation. This leads to recommending best lablab accessions to be registered for the Tepi area and other similar agroecologies. Furthermore, recommended varieties should be evaluated through animal performance through feeding trials. Refining the main agronomic practice such as time of sowing, application of fertilizer, harvesting time, identifying best food crop-lablab integration methods, and feeding strategies is also vital to address in the future.
