Low heritability and high genotype × environment interactions make the trait-based breeding strategy an unreliable approach. This study was planned to identify the drought-tolerant lines by evaluating yield-based selection indices in a recombinant inbred line (RIL) population derived from an inter-specific cross between drought-tolerant genotype GPF 2 (<jats:italic>Cicer arietinum</jats:italic> L.) and drought-sensitive accession ILWC 292 (<jats:italic>C. reticulatum</jats:italic>) at two locations in India (Ludhiana and Faridkot). A total of six yield-based selection indices were calculated and significant variation was observed in the RILs and their parents for yield-based selection indices at both locations. A holistic approach across association analysis and principal component analysis identified drought tolerance index, mean productivity, geometric mean productivity and harmonic mean productivity as key selection indices, which could be used for indirect selection of drought-tolerant lines. Overall, on the basis of these approaches, a total of 15 promising RILs were identified for their use in chickpea breeding programme for developing drought-tolerant cultivars.","PeriodicalId":20188,"journal":{"name":"Plant Genetic Resources","volume":"233 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140035164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing three crucial crosses between petalous (Pant Sweta, Pant Girija, YSH0401) and ‘apetalous’ parents, we observed the absence of apetalous plants in the F<jats:sub>1</jats:sub> generation, indicating dominant inheritance of petalous plants. The F<jats:sub>2</jats:sub> generation consistently displayed a 3:1 ratio of petalous to apetalous plants, confirming the dominance of the petalous trait. Chi-squared tests on each generation supported this conclusion. Backcrosses with petalous parents yielded no fruit, reinforcing the dominance of the petalous trait. Chi-squared tests on these backcrosses further confirmed the dominance inheritance pattern. Conversely, backcrosses with apetalous parents consistently exhibited a 1:1 ratio, highlighting the recessive nature of the apetalous trait.

In the present investigation, a total of 21 genotypes of dolichos bean, comprising local collections mainly, along with one standard check (Kashi Sheetal) were evaluated in a complete randomized block design with three replications for two consecutive years, 2021–22 to 2022–23 for the perusal of the genetic variability. Analysis of variance revealed significant differences among all the genotypes for all the characters. PCV and GCV estimates revealed very little influence of environment on the expression of traits under study. High heritability (&gt;90%) estimates coupled with high genetic advance as a percent of the mean were observed for flower attributes, pod length, average weight of 10 pods, pod yield and protein content. The principal component analysis revealed that the first two components cumulatively accounted for more than 50% of total variability. The present investigation revealed that the genotypes, RLBDL-S-8, RLBDL-S-14 and RLBDL-S-4-5 were stable across the years and genotype RLBDL-S-8 exhibited the highest yield potential, which can be used effectively in the development of high yielding varieties of dolichos bean in the Bundelkhand region. The study also revealed the presence of wide genetic variability in the studied local accessions which is a prerequisite for the genetic improvement of crop plants.

Greece with a favourable environment all-round the year, has become a major competitor in tomato production around Europe. However, there is an increasing demand to improve tomato crop, to withstand harsh environmental conditions (extreme temperatures, salinity, etc.), and to develop high-quality final products. People have devoted a significant effort to crop improvement through phenotypic screening resulting in a large number of tomato landraces. An increasing demand to clarify the relationships among local tomato landraces and hybrids utilizing the most preferred molecular markers the simple sequence repeats (SSR-markers) is the main objective of this study. Twenty-seven tomato landraces and two tomato hybrids cultivated in Crete, Greece, were genotyped utilizing eleven simple sequence repeats (SSR) along with the Structure analysis of the germplasm. A neighbour-joining dendrogram of the 27 landraces and the two hybrids was produced. The Structure analysis indicated that nine ancestral populations are hidden inside the group of all the genotypes tested, using Evanno's method. The final objective was to make these data publicly available through the first Greek relational database (Greek Tomato Database-GTD). GTD was developed allowing the users to update and enrich the database, with new and supplemental information.

The results showed that total phenolic content (TPC), total flavonoid content (TFC) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity in the leaves of Sarbisheh were higher than in other treatments. The amount of TPC, TFC and DPPH scavenging activity in leaves was higher than in other tissues in the Sarbisheh population, increasing by 31 and 70%, 41 and 20%, 8 and 13%, respectively, over that of flowers and fruits.

Four different genotypes of snapmelon (<jats:italic>Cucumis melo</jats:italic> L. var. <jats:italic>momordica</jats:italic>) responded differently to 0, 7 and 21 d of simulated drought stress. Information was collected on a range of morpho-physiological, biochemical and molecular characteristics. Each genotype had longer roots, though BAM-VR-312 had the longest roots overall. As the severity of the drought grew, the net photosynthetic rate (Pn) and stomatal conductance (Gs) dropped. In BAM-VR-312, a smaller decline in relative water content (RWC) was recorded, despite the fact that drought stress caused a significant fall in RWC. BAM-VR-312 had smaller accumulations of electrolyte leakage, hydrogen peroxide, phenol and malondialdehyde, although proline content was greater. A decrease in photosynthetic pigments was noted, though BAM-VR-312 had the least reduction. Antioxidant enzyme activity increased in BAM-VR-312, as evidenced by records of ascorbate peroxidase, catalase, guaiacol peroxidase, glutathione reductase and superoxide dismutase. Similarly, expression level of their respective genes was recorded highest in BAM-VR-312.

Lentil (<jats:italic>Lens culinaris</jats:italic> Medikus) plays a vital role in ensuring global food and nutritional security. Traits like early flowering enable the crop to mature faster, thereby shortening the growing window and reducing yield losses caused by moisture and heat stresses during the reproductive phase. However, issues like limited genetic diversity in this trait remain unaddressed. To address this gap, our study aims to comprehensively assess genetic variability and trait associations in 158 lentil accessions. In the present study, we observed significant variations for days to 50% flowering (67–90 days), days to maturity (109–122 days) and 100 seed weight (1.69–2.68 g) throughout a period of two consecutive years (2020–2021 and 2021–2022). The observed variability in these traits offers a valuable avenue for the improvement of lentil yield through targeted selection and hybridization. Additionally, correlation analysis showed negative correlation between days to 50% flowering and grain yield per plant, while plant height had a significant (<jats:italic>P</jats:italic> &lt; 0.01) positive correlation with all traits except yield per plant. Furthermore, we identified specific germplasm with exceptional traits that hold significant potential for future breeding programmes.
