Hybrid rice

Hybrid technology in many crops has contributed 20-30 per cent increase in the production and exploitation of heterosis through the development of F1 hybrids which has been recently deployed in rice with yield advantage of 20-25 per cent over best pure lines. The main aim of any plant breeding programme is to develop special high yielding hybrids and success of any plant breeding programme depends on the choice of appropriate genotypes as parents in the hybridization programme.

A putative transcription factor, named RAMY, that binds to the 20-bp O2S sequences of the regulatory region of the Amy2genepromoter has been identifiedusing the yeast one-hybrid system from a rice library. The full lengthRAMY cDNA clone encodes a 218-amino acid protein and is homologous to the late embryogenesis-abundant protein (LEA5). In vitromutagenesis and electrophoretic mobility shift assays confirmed that RAMY can bind with O2S spe-cifically throughanunusual zincfingerwithaCXCX4CX2H consensus sequence. ...

In a pot experiment was conducted to evaluate the physiological characteristics and root characteristics associated with drought tolerance of rice varieties including indica rice subspecies, japonica rice subspecies, hybrid male sterility line and temperature sensitivity of wild rice species for comparison with drought-tolerant Indica rice varieties. At the effective tillering, the pot experiment was to drain the water and then dried for 4 days, then watered again.
