The present investigation for studying correlations and path analysis estimates grain yield contributing characters in maize was carried out at Maize Research Centre Seed Farm, Devihosur eleven characters. Days to 50 per cent tasseling significantly positively correlated with days silking negatively plant height, ear cob length, shelling percentage, hundred weight yield. significant percentage ...

In maize (Zea mays L.), GSp1, the predominant GS isozyme of the developing kernel, is abundant in the pedicel and pericarp, but absent from the endosperm and embryo. Determinations of GSp1 tissue distribution in vegetative tissues have been limited thus far to root and leaves, where the isozyme is absent. However, the promoter from the gene encoding GSp1 has been shown to drive reporter gene ex...

Fungi in the genus Fusarium are very common associates of maize (Zea mays L.) plants. These fungi can cause disease at all developmental stages of the plant, but also may infect plants without causing symptoms (24). Certain Fusarium species, particularly F. verticillioides (Sacc.) Nirenberg (synonym = F. moniliforme J. Sheld.) and F. proliferatum (T. Matsushima) Nirenberg, often infect maize pl...

Maize (Zea mays L.) is a host to numerous pathogenic species that impose serious diseases to its ear and foliage, negatively affecting the yield and the quality of the maize crop. A considerable amount of research has been carried out to elucidate mechanisms of maize-pathogen interactions with a major goal to identify defense-associated proteins. In this review, we summarize interactions of mai...

T HE extent of infection of the corn grain by fungi of various kinds is an important item in the grading of corn by physical or chemical means or by performance tests. It may also be an important item in the feeding value of the grain for livestock. Mitchell and Beadles (i94o) have studied the impairment in the nutritive value of corn by various types of ear rot, using growing albino rats as te...

The maize sex determination pathway results in the arrest of stamen in ear spikelets and the abortion of pistils in both the tassel spikelets and in the secondary florets of ear spikelets. Arrested stamen cells showed no signs of DNA fragmentation, an absence of CYCLIN B expression, and an accumulation of the negative cell cycle regulator WEE1 RNA.
