Paithumbase is an established database for identifying the phenotypic variations of the mungbean germplasm accessions preserved in the National Pulses Research Centre, Tamil Nadu Agricultural University. This database provides information on both quantitative and qualitative traits of the mungbean germplasm. The database architecture was built with a GUI interface, developed in PHP and HTML as ...

Breeders normally select simultaneously for several traits in various environments. We investigated the effects of the progeny x environment interaction on success in selection for several traits. The population used was obtained from a cross between the CVIII-85-11 line, which has a semi-erect to prostrate plant architecture and a cream with brown streaks bean type, and the BRS-Supremo cultiva...

Autopolyploid plants and their organs are often larger than their diploid counterparts, which makes them attractive to plant breeders. Mulberry (Morus alba L.) is an important commercial woody plant in many tropical and subtropical areas. In this study, we obtained a series of autotetraploid mulberry plants resulting from a colchicine treatment. To evaluate the effects of genome duplications in...

In-field infection of maize (Zea mays L.) ears by the fungus Aspergillus flavus Link:Fr causes pre-harvest aflatoxin contamination grain. Germplasm lines with host-plant resistance to accumulation are available breeders, but these often possess undesirable agronomic characteristics. Commercial expired plant variety protection (ex-PVP lines) a potential source elite germplasm public breeders. A ...

The Honeycomb Selection Design (HSD) is an innovative experimental method whose main feature the even and systematic entry arrangement. Its systematicity, if combined with absence of inter-plant competition that maximizes phenotypic expression differentiation individual plants, enables implementation single-plant selection as early initial generations genetic segregation, facilitating plant bre...

Th e world's food production systems must keep up with an ever-increasing demand in spite of the challenges caused by climate change and environmental degradation. To meet this challenge, plant breeders must have access to genetic diversity for crop improvement. However, genetic homogeneity in the handful of major crops that feed the world limits options for breeding progress (Swaminathan, 2009...

The fundamental discoveries of Darwin and Mendel established the scientific basis for plant breeding and genetics at the turn of the 20th century. Similarly, the recent integration of advances in biotechnology, genomic research, and molecular marker applications with conventional plant breeding practices has created the foundation for molecular plant breeding, an interdisciplinary science that ...
