Sustainable use of plant protection products in Nigeria and challenges
Nigeria’s drive to boost food security and to fight off insect pests and yield-limiting crop pathogens has led to an unintended consequence: the mass importation and build-up of obsolete and toxic pesticides. Nigerian farmers have been relying heavily on these agrochemicals for the control of various weeds, insect pests and pathogens, leading to the high importation of these products. Although...

Effect of Eucalyptus pollen isolation methods on pollen viability, debris content, quantity isolated and pollen density per stigma
Success of interspecific hybridization in Eucalyptus depends on the availability of contamination free, clean and viable pollen from elite paternal trees. Unlike the natural process of open pollination, control pollination (CP) in Eucalyptus orchards, is a slow, tedious and labour-intensive procedure that involves high costs, but results in low seed yields. In order to overcome these...

Agronomic and molecular evaluation of recombinant inbred lines (RILs) of lentil
Sequence-related amplified polymorphism (SRAP) and morphological markers were studied to compare the efficiency of both marker systems in the evaluation of twenty five lentil (Lens culinaris Medik.) recombinant inbred lines (RILs) and four testers. Data on 13 morphological traits were collected and analyzed. A total of 240 polymorphic SRAP’s bands (76.7%) were scored using four...

Screening of superior chickpea genotypes for various environments of Iran using genotype plus genotype × environment (GGE) biplot analysis
Superior crop cultivars must be identified through multi-environment trials (MET) and on the basis of multiple traits. The objective of this study was to explore the effect of genotype (G) and genotype × environment interaction (GE) on grain yield of 17 chickpea genotypes (Cicer arietinum L.) in six different research stations of Iran. GGE (G plus GE) biplot methodology was used to evaluate...

Genetic diversity for sustainability of rice crop in Indian Punjab and its implications
The varietal diversity in rice crop in Indian Punjab has been increasing at a fast rate due to variable soil and climatic conditions and variable objective functions of the farmers. In spite of the fact that productivity of rice increased over time, as a result of improvement in technology and its fast adoption, the declining resource base, particularly water, soil health and pest resistance, the genetic...
