This study evaluated agronomic traits of 111 genotypes of black gram Vigna mungo (L.) Hepper, mainly from Pakistan, to determine the extent of genetic diversity. Seed proteins were analyzed by SDS-PAGE. High genetic variance was observed for days to flowering, days to maturity, number of branches/plant, number of pods/plant, biomass/plant, grain yield/plant and harvest index, whereas low geneti...

Tree breeders face the problem of negative correlations between wood properties and growth traits. It is necessary to overcome this difficulty in order to obtain promising genotypes. The selection index is one of the helpful tools in this process, because it allows multiple features of interest to be selected. In this study, a multiple trait selection index for Khasi pine (Pinus kesiya Royle ex...

Mosquito control with the use of insecticides is faced with the challenges of insecticide resistance in disease vectors, community refusal, their high cost, operational difficulties, and environmental concern. In view of this, integrated vector control strategies with the use of larvivorous fishes such as Guppy (Poecilia reticulata) and Gambusia (G. affinis) as biological control agents were us...

Narrow migration corridors known in diurnal, social migrants such as raptors, storks and geese are thought to be caused by topographical leading line effects in combination with learning detailed routes across generations. Here, we document narrow-front migration in a nocturnal, solitary migrant, the common cuckoo Cuculus canorus, using satellite telemetry. We tracked the migration of adult cuc...

Sugarcane is the most important sugar and bioenergy crop in the world. The selection and combination of parents for crossing rely on an understanding of their genetic structures and molecular diversity. In the present study, 115 sugarcane genotypes used for parental crossing were genotyped based on five genomic simple sequence repeat marker (gSSR) loci and 88 polymorphic alleles of loci (100%) ...

The power of selection is illustrated by the increase in the average annual yield of dairy cows in Sweden in kg fat-corrected milk from 2,500 kg in the year 1900 to 8,200 kg in 1997. More than a half of this improvement has a genetic origin. The breeding goal for dairy cattle has successively been broadened to cover traits other than production. The prerequisites for a successful breeding progr...

problem in major rice growing areas where there is acute scarcity of water and rainfed cultivation depends on the seasonal rainfall. So, order to overcome for cultivation, breeders have made prompt efforts breed genotypes which can tolerate drought stress condition. develop such an efficient breeding programme, selecting plants with desirable root characters one objectives that enables withstan...

ABET 2000 requires new approaches to quality control and continuous improvement in engineering programs. It is instructive to analyze this control in terms familiar to the engineering community and to consider the implications for classroom and program level practices. A common approach to program assessment is to monitor student and graduate success statistically. This is analogous to using st...

In this study, breeding structures and commercial sow lines were evaluated by economic and genetic simulation studies for their suitability to provide the Dutch organic pig sector with replacement gilts. Sow and litter performance from over 2000 crossbred sows from 2006 to 2007 were collected on 11 to 14 Dutch organic pig herds, respectively, and compared with conventional herds. Results showed...
