Abstract:
... Non-availability of genetic male sterility (GMS) in genetically diverse genotypes and the problem of rouging fertile plants in hybrid plot necessitated the development and testing of new F ₁ hybrids of chili pepper (Capsicum annuum L.) using cytoplasmic-genetic male sterility (CGMS) system and identifying good combiner inbred lines for transferring male sterility system in to them. Twelve inbred l ...

Abstract:
... St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze] is a warm season turfgrass and is widely used for lawns and landscapes in the southern United States of America. The southern chinch bug (Blissusinsularis Barber) is the most damaging insect of St. Augustinegrass. Use of resistant cultivars is an environmentally sound and sustainable method to control this insect pest. Two newly identifie ...

Lablab purpureus; chi-square distribution; germplasm; multivariate analysis; quantitative traits; variance
Abstract:
... Development of a reduced representative set of a large base collection enables greater use of genetic resources in crop improvement programs. Efficiency of standard stratified clustering (SSC) and heuristic approaches were compared for developing core sets of Dolichos bean from a base collection of 648 accessions on the basis of data on 21 qualitative and 20 quantitative traits. The SSC approach w ...

Subject:
Hypera postica; Medicago sativa; Onobrychis viciifolia; alfalfa; crop yield; field experimentation; forage production; intercropping; land values; pests; population growth
Abstract:
... Diversification of varieties or species within the same field can result in reduced pest population and increased yields. To study the forage production and alfalfa weevil (Hypera postica) population in alfalfa (Medicago sativa L .) and sainfoin (Onobrychis sativa) intercropping, a field experiment was carried out as a split-plot in time across 2 years (2010–12) with three replications. Treatments ...

Subject:
Paspalum scrobiculatum; cluster analysis; culms; early development; genetic improvement; genetic variation; genotype; germplasm; grain yield; lodging
Abstract:
... Presence of genetic diversity is a prerequisite for genetic improvement of any crop. As lodging and associated grain loss is a problem in kodo millet, a study was undertaken to characterize and assess the diversity in kodo millet germplasm accessions for culm strength and grain yield-related traits. Principal component and cluster analyses were performed for grouping the genotypes and to identify ...

Abstract:
... Genetic linkage maps are deployed to locate quantitative trait loci (QTL) of traits of interest and speed up breeding programs. In this study, we used two Vicia faba L. backcross families (BCFams). Genetic linkage maps were constructed with 193 and 288 polymorphic amplified fragment length polymorphism (AFLP) markers using 131 and 132 individuals for BCFam1 and BCFam2, respectively. The BCFam1 lin ...

Abstract:
... Cassava is an economically important crop in Thailand. ‘Hanatee’, a Thai variety of cassava, was used to develop microsatellite markers from an enriched-genomic DNA library using (GAT) ₈, (GGA) ₈, and (AAAC) ₆ oligonucleotide repeats. Thirty-two primer pairs were developed and used to evaluate 40 M. esculenta Crantz samples originating from 15 countries. Nine polymorphic loci were identified with ...

Abstract:
... Broccoli (Brassica oleracea var. italica) is an important nutritionally rich vegetable cole crop grown in the world. Environmental stress, pests, and diseases cause enormous yield losses because of a limited gene pool. Genetic manipulation is becoming an important method for broccoli improvement. The objective of present study was to evaluate the potency of thidiazuron (TDZ) as a plant growth regu ...
