BACKGROUND AND AIMS Most plant scientists, in contrast to animal scientists, study only half the organism, namely above-ground stems, leaves, flowers and fruits, and neglect below-ground roots. Yet all acknowledge roots are important for anchorage, water and nutrient uptake, and presumably components of yield. This paper investigates the relationship between domestication, and the root systems ...

The eggplant (Solanum melongena L.), also known as aubergine or brinjal, has been cultivated for centuries in the Old World and is currently a crop species of global importance. Despite this, hypotheses of eggplant evolution have been fraught with controversy. Previous conclusions have relied solely on morphological characters or have been based on insufficient taxonomic sampling, leading to co...

A new sexannulate species of the genus Orobdella Oka, 1895, Orobdella mononokesp. n., is described on the basis of five specimens collected from Yakushima Island, Japan. Orobdella mononokesp. n. differs from other sexannulate Orobdella species in its possessing the following combination of characters: dorsal surface bicolor in life, I-XIII, XXVII and caudal sucker grayish purple, XIV-XXVI amber...

Wheat is an important cereal crop of the world and its productivity has been limited by abiotic stresses. An experiment was conducted at the Department of Plant Breeding and Molecular Genetics, Faculty of Agriculture, The University of Poonch Rawalakot, to assess the genetic diversity for drought tolerance in synthetic wheat double haploids. On the bases of cluster analyses, the genotypes were ...

nical ability for plant transformation increases daily, the practicality of using transgenic plants in complex The halobacteria are the only organisms that are tolerbreeding programmes seems rarely to be given enough ant of salinity at the molecular level. All other bacteria, thought. If intervention at the molecular level is to lead all fungi, all plants, and all animals avoid the need for to ...

Genetic diversity is prerequisite for any crop improvement program as it helps in the development of superior recombinants. Fifty Malaysian upland rice accessions were evaluated for 12 growth traits, yield and yield components. All of the traits were significant and highly significant among the accessions. The higher magnitudes of genotypic and phenotypic coefficients of variation were recorded...

Soybean (Glycine max (L.) Merrill) is the only oilseed crop having richest source of quality protein (~ 40%) apart from 20% edible and share 22 % oil requirement country. The present study was carried out to estimate important genetic parameters such as genotypic coefficient variance (GCV), phenotypic (PCV), heritability (h2) expected advance (EGA).Thirty-five soybean genotypes collected differ...

Northeast India is rich in genetic diversity of horticultural crops and colocasia one the important crops. This region for both cultivated wild species particularly jhum fields, homestead gardens, near water bodies, river banks, forests road sides. Wide range variability observed vegetative characters, corm cormel yield quality characters.  It field as a mixed crop along with paddy other l...

Construction of a genetic linkage map is necessary to apply marker-assisted selection tools in a crop improvement program. Except for the recent studies from two laboratories, most of the previous studies have shown little or no DNA polymorphism in cultivated groundnut (Arachis hypogaea L.). In the present study, 70 selected genotypes, representing variability for several morphological, physiol...

A field study was conducted at Sardarkrushinagar in North Gujarat during crop season kharif 2012 to know the existence of genotype x environment interaction and stability for yield and yield attributes in three different environments. The experiment was laid out in a randomized complete block design replicated thrice. Stability parameters that are useful tools for identification of genotypes wi...
