Maize is one of the most important crops, both worldwide and in Romania, preserving diversity biological material used breeding this plant particular importance. The Agricultural Research Development Station (ARDS) Turda, inbred lines collection includes its own genotypes some obtained as a result germplasm exchanges with other institutions country or abroad. In present study, 575 created at Tu...

In the sub-tropics, water and nitrogen are the most important factors limiting the grain yield of maize. The effect of nitrogen (N) rates and drought stress at different growth stages of maize were investigated. Nitrogen treatments consisted of 100, 150, and 200  kgN.ha-1 from the urea source while water stress treatments were composed of irrigation-off since the early 10-leaf stage to emergenc...

IV INHERITED condition of pollen abortion is frequently found in many A species of plants. In maize 20 genes for male sterility are listed by EMERSON, BEADLE and FRASER (193.5). Male sterile-1 reported by SINGLETON and JONES (1930) is on chromosome 6 closely linked with the Y y endosperm locus. All of the gene steriles described are independent recessives, each capable of bringing about either ...

The maize P1-rr gene encodes a Myb-homologous transcription factor that regulates the synthesis of red flavonoid pigments. Maize plants transformed with segments of the P1-rr promoter driving a GUS reporter gene exhibit significant variation in transgene expression, both between independent transformation events and among sibling plants derived from a single event. Interestingly, variability in...
