The tassel seed mutations ts4 and Ts6 of maize cause irregular branching in its inflorescences, tassels, and ears, in addition to feminization of the tassel due to the failure to abort pistils. A comparison of the development of mutant and wild-type tassels and ears using scanning electron microscopy reveals that at least four reproductive meristem types can be identified in maize: the inflores...

We characterized allelic variation at barren inflorescence2 (bif2), a maize co-ortholog of the Arabidopsis PINOID protein kinase (PID), and tested for trait associations with bif2 in both an association mapping population of 277 diverse maize inbreds and in the inter-mated B73 x Mo17 (IBM) linkage population. Results from the quantitative analyses were compared with previous reports of bif2 phe...

Studies of the morphology of the corn plant have led, according to Weatherwax (17) j^ to clearer and simpler explanations of the results of certain experiments with corn. It should be expected that further studies of the developmental morphology might prove to be equally helpful. Variations from the normal sequence of development which lead to abnormalities of the tassel and ear and variations ...

The twisting process of Sirospunning and Ringspunning was compared and analyzed as to the phenomenon that Sirospunning decreases yarn hairiness. It can be obtained from the analysis of geometrical model that more hairiness is twisted into the yarns and the amount of apparent hairiness is reduced through its special twisting. It can be calculated that when the count is equal Sirospunning can red...

In this study, tassels of Cave-in-Rock (upland) and Alamo (lowland) were removed at or near tassel emergence to explore its effects on biomass production and quality. Tassel-removed (TR) Cave-in-Rock and Alamo both exhibited a significant (P<0.05) increase in plant heights (not including tassel length), tiller number, and aboveground biomass dry weight (10% and 12%, 30% and 13%, 13% and 18%, re...

Evaluation of the genetic variability, heritability and advance traits is an essential task in any plant improvement program. Twenty maize genotypes were replicated twice a randomized complete block design on research plot Prithu Technical College, Deukhuri Dang Nepal from June 2017 to September determine heritability, for different agronomic traits. Analysis variance showed significant differe...

Any altered plant phenotypic expression is a variation that may be desirable or undesirable. Mutants form one such class which has been exploited in past and have role to play in future. One of the aspects in utilizing the worth of mutants is conversion of normal maize into quality protein maize (QPM). In the current investigation we have found a number of plants in the BC2F1 populations whose ...

Paddystem borer (Scirpophaga incertulas) is a serious rice pest. The damaged plants wither into dead tassel or white tassel. Such damage leads to decreased in rice production. In order to control the damages of paddystem borer efficiency, it is very important to analyze and study the regulation of population dynamics and the related factors affecting the development. This investigated the popul...
