Preliminary Characterization and Evaluation of Landraces of Indian Spinach (Basella spp. L.) for Agro-economic and Quality Traits

Abstract

Indian spinach (Basella spp. L.) is an underutilized and underexploited indigenous leafy vegetable which has high nutritional and medicinal value and extensively used in the sub-continent. Landrace germplasm is endowed with rich genetic variability for various yield and quality traits. A total of six accessions collected through an exploration during 2010 were pre-bred by selfing during the October-January cropping season in 2011. These landraces were evaluated in a randomized block design with four replications in June-September, 2012 at Vegetable Research Station, Dr. Y. S. R. Horticultural University, Rajendranagar to assess the genetic diversity, variability, heritability and genetic advance for yield and its components in the material. Multivariate analysis following Ward's minimum variance-method revealed distinct clustering pattern. Analysis of variance revealed highly significant differences among all genotypes for all the studied traits indicating considerable variability among ecotypes for most of the measured parameters. There was significant variability for genetic potential of all genotypes for different traits under study. The highest variability at genotypic level was observed for stalk yield (73.95%) followed by leaf-stalk ratio (46.70%) and weight of tender shoot (41.25%). Low to high estimates of broad sense heritability were found in different traits. High estimates of heritability (>60%) coupled with high genetic advance as percent of mean (>20%) for petiole length, internodal length, weight of tender shoot, stalk yield, leaf-stalk ratio and harvest index revealed that most likely the heritability is due to additive gene effects and selection may be effective.

EST-SSR Based Genetic Diversity and Population Structure among Korean Landraces of Foxtail Millet (Setaria italica L.)

“…According to Deb (2009), collection and maintaining landraces diversity can ensure agricultural sustainability and food security. Knowledge of the genetic diversity and the population structure of germplasm collections is an important foundation to understand the genetic relationship, diversity, and population structure among cultivated species (Reddy et al, 2014).…”

Genetic Divergence Analysis of Inbred Lines of Okra [Abelmoschus esculentus (L.) Moench]

“…To meet the demand of ever growing human population in the country, it is thus imperative to find alternative means for increasing the yield potential of okra in a sustainable manner. A successful variety in any vegetable crop must meet minimal criteria for numerous traits that are potentially valued in the markets (Reddy et al, 2014). Superiority for multiple 'yield' and 'quality' traits is essential for economic sustainability of a variety (Reddy et al, 2014).…”

Superiority for multiple 'yield' and 'quality' traits is essential for economic sustainability of a variety (Reddy et al, 2014). The major emphasis in okra breeding is on the development of HYVs coupled with acceptable pod quality and resistance to yellow vein mosaic virus (Reddy et al, 2012b The present investigation was therefore, undertaken to assess the nature and magnitude of genetic diversity available in the genotypes of okra on the basis of various growth, earliness and yield attributes.…”

Management of Cercospora Leaf Spot of Indian Spinach (Basella alba L.) with BAU Bio-fungicide and a Plant Growth Promoting Hormone

“…Indian spinach (Basella alba L.) belongs to the family Basellaceae is an indigenous, rapidly growing, tropical leafy vegetable [1,2] commonly grown as backyard plant in the home gardens. It is originated from India or Indonesia [3], however; it is also popular in tropical and subtropical region including Asia, America, Africa, Madagascar etc.…”

“…It is originated from India or Indonesia [3], however; it is also popular in tropical and subtropical region including Asia, America, Africa, Madagascar etc. [2]. The vegetable has other interesting common names in different region like Ceylon spinach, Malabar spinach, saan choy (Chinese), mongtoi (Vietnamese), alugbati (Philippines), puisaag (Bengali), remayong (Malay) etc.…”
