Allele-specific PCR (AS-PCR) with 3 primers was used to identify true F1 hybrids resulting from normal oleate groundnut cultivars pollinated with high oleate groundnut genotypes with a 1-bp insertion (A:T) at position 442 after the start codon in FAD2B. Its reliability was confirmed by direct sequencing of FAD2B PCR products. The AS-PCR protocol requires minimal resources, and thus provides an ...

In recent times efforts are being made to improve the productivity of bambara groundnut. Studies were initiated (i) to characterise and evaluate landraces and to select superior ones for irradiation, (ii) to induce genetic variation through gamma irradiation and (iii) to use biotechnological approaches to shorten the generation cycle. The results of the study indicated that gamma irradiation in...

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...

Aims: To investigate the combined effect of Arbuscular Mycorrhizal Fungi (AMF) and intercropping on control nematode Radopholus similis in banana.
 Study Design: The study involved an experiment which banana-banana monocrops alongside banana-groundnut banana-sweet potato intercrops were inoculated with AMF Rhizophagus irregularis MUCL 41833 to R. similis.
 Place Duration Study: Centre...

The goal of achieving concrete with adequate durability properties in terms reduced susceptibility to alkali-silica and mechanical-strength behaviour has led several high-performance materials development. While the use Bambara nut shell ash is gaining acceptance various applications, mineralogical composition such by-product cannot be easily controlled as a manufactured pozzolan. In this resea...
