The environment can influence heterosis, the phenomena in which the offspring of two inbred parents exhibits phenotypic performance beyond the inbred parents for specific traits. In this study we measured 25 traits in a set of 47 maize hybrids and their inbred parents grown in 16 different environments with varying levels of average productivity. By quantifying 25 vegetative and reproductive tr...

Several inbred lines of rats were produced from noninbred stock of Dahl salt-sensitive (S) rats, and several inbred lines were also produced from noninbred stock of Dahl salt-resistant (R) rats. There were significant differences (p less than 0.001) in blood pressure response to a high salt diet among the inbred S lines produced, which indicates that the original S stock obtained from Brookhave...

Glucosinolates are the biochemical compounds that provide defense to plants against pathogens and herbivores. In this study, the relative expression level of 48 glucosinolate biosynthesis genes was explored in four morphologically-different cabbage inbred lines by qPCR analysis. The content of aliphatic and indolic glucosinolate molecules present in those cabbage lines was also estimated by HPL...

Accurate data and relevant insights on parental corn inbred lines' hybrids’ genetic purity diversity are essential for hybrid development seed production. Here, the of 19 yellow lines were assessed using SSR markers. A total 91 markers utilized, which 61 highly polymorphic had high polymorphism information content value (PIC = 0.379). Genetic parameters calculated from generated marker data. Ob...

We determined virulence of seven Heterorhabditis bacteriophora strain GPS11 inbred lines possessing superior infective juvenile longevity, and heat and ultra violet radiation tolerance against white grubs Popillia japonica and Cyclocephala borealis. At 1 and 2 weeks after treatment, inbred line A2 was significantly more virulent towards P. japonica compared to the parent strain GPS11 and inbred...

THAT mouse Mecca, the Jackson Laboratory, has repeatedly pioneered in bringing mouse genetics to its present state. There was George Snell’s NobelPrize-winning work on histocompatibility, Roy Stevens’ work on embryonal carcinoma, Tibby Russell’s on hematopoiesis, and many others (reviewed by Paigen 2003a,b). It has also been the site of several important methodological innovations. First and mo...

The seed proteome of two traditional maize inbred lines (pb269 and pb369) contrasting in grain hardness and in preferable use for bread-making was evaluated. The pb269 seeds, of flint type (i.e., hard endosperm), are preferably used by manufacturers, while pb369 (dent, soft endosperm) is rejected. The hypothesis that the content and relative amounts of specific proteins in the maize flour are r...
