Performance evaluation of double type tuberose IIHR-4 (IC -0633777) for flower yield. quality and biotic stress resistance/tolerance

An experiment was carried out to evaluate an advance breeding line of tuberose double type IIHR-4 along with check for flowering, yield and resistance root knot nematode Alternaria leaf burn disease. The hybrid selection developed through hybridization by crossing Mexican Single x Pearl Double, followed selection. Double found be novel better flowering quality traits such as short spike (62.00 cm), rachis length (25.59cm), diameter floret (4.47cm) number florets per (50.75). spikes exhibited more open at a time in (7.10) the shorter internodal 3.45cm. are (5.22cm) arranged very compactly on making ideal cut flower. highly resistant Meloidogyne incognita under field conditions tolerant
