|Abstract: ||Fourteen promising F1 hybrids of Watermelon namely IIHR-188 X IIHR-118, IIHR 114 X IIHR 118 , IIHR 119 X IIHR-20-1, Arka Manik X IIHR 46, IIHR 43 X IIHR 46, Arka Manik X IIHR-188, Arka Jyothi ,NS-295, Kushboo, Madhubala, Apporva, CWH-7 and Riya were evaluated in the experimental plots of Division of Vegetable Crops, Indian Institute of Horticultural Research, Bangalore during 2002-04. Information about various biometrical characters such as fruit length (cm), fruit girth (cm), days to first male flower opening & female flower opening, Rind thickness(cm) and TSS (%) along with Yield (t ha-1), were utilized to develop stability models with a view to identify the stable hybrid(s) for wide range of cultivation.
Stability models developed indicated that two hybrids viz., Arka Jyothi (with yield potential of 75.91 t ha-1), across the years and NS-295 (64.25 t ha-1), were stable for wide range of cultivation. Statistical measures of stability viz., regression coefficient, deviation from regression co-efficient and ecovalence measures were worked out and utilized for grouping of hybrids into different categories based on their cumulative performance over year.|
