Not AvailableIndian bean [Lablab purpureus (L.) Sweet] is an underexploited nutritious legume vegetable found in tropical regions of Asia and Africa. The nutritional and anti-oxidant properties of 21 pole type Indian bean genotypes were analysed in edible pods in terms of protein, sugar, chlorophyll, carotenoids, phenol, and proline contents. The analyses revealed a significant genotypic variation in the level of protein (102-635.6 mg), sugar (0.188-1.11 mg), chlorophyll (0.121-0.716 mg), phenol (1.7-9.67 mg), proline (0.02-7.06 μg) and carotenoids (0.04-0.231 mg).Estimation of genetic variability parameters revealed that chlorophyll a and non-reducing sugar had high estimates of PCV than GCV, whereas, protein, phenol, chlorophyll b, carotenoid, reducing sugar and non-reducing sugar had moderately high PCV than GCV indicating that such variability could be exploited for successful identification of genotypes for the specific biochemical property. In general, heritability estimates were recorded to be high for all the characters studied except chlorophyll a and reducing sugar. High heritability coupled with high genetic advance as percentage of mean was observed for proline, non-reducing sugar, chlorophyll a, carotenoidd, protein and phenol. Since such traits are controlled by additive genes, more importance need to be given to these traits while selecting the breeding lines rich in nutritional qualities.Not Availabl

Not AvailableGenetic diversity in 143 Indian bean [Lablab purpureus (L.) Sweet] accessions from India was assessed using simple sequence repeat (SSR) markers. A total of 134 SSR markers developed from common bean, cowpea, mung bean, moth bean and Faba bean were used to assess their transferability to Indian bean. Quantitative traits as well as SSR marker data was used to analyse the genetic diversity analysis in 143 Indian bean accessions from different agroecological zones of India. Of the 134 SSR primers, 55 (41.0%) were found to be transferable since they showed reproducible polymorphic amplification products in Indian bean. The SSR primers derived from common bean fail to amplify any product in Indian bean. The results indicated that there is a potential for transferring SSR markers within legumes. The identification of a set of transferable SSR markers would enable the application of the SSR technology in Indian bean molecular research. To our knowledge, this is the first ever attempt to evaluate cross-species microsatellite (SSR) markers for a possible dissection of genetic diversity in Indian bean.Not Availabl
