|Abstract: ||Watermelon [Citrullus lanatus (Thunb.) Matsum & Nakai] is the most important Cucurbitaceous vegetable crop grown for its fleshy, juicy and sweet fruits. It is extensively cultivated both under irrigated and riverbed cultivation. In India, watermelon is grown in an area of 28,000 ha with a production of 2,05,885 t (NHB-2004). With increasing interest in hybrid seeds and the advanced scientific researches, especially on hybrid seed production techniques, the seeds of superior hybrids in watermelon can be made available to the growers at reasonable prices. During 2004, research work was initiated at Indian Institute of Horticultural Research, Bangalore, on the development of F1 hybrids in watermelon for high yield and quality parameters. During the last three years , 43 F1 hybrids were developed and evaluated. Based on yield performance, ten superior F1 hybrids were short listed and evaluated in RBD with three replications along with commercial check NS-295, during rabi summer seasons of 2006-07, 2007-08 and 2008-09. During 2006-07, ten F1 hybrids were evaluated, of which the F1 hybrid WH-35 gave the highest fruit yield of 66.21 t/ha, followed by the hybrid WH-24 (50.64 t/ha) , whereas the commercial check NS-295 gave an yield of 38 t/ha. During 2007-2008, the hybrid WH-24 gave the highest fruit yield of 84.18 t/ha, which differed significantly from rest of the hybrids evaluated. This was followed by the hybrids WH-35 (60.20 t/ha) and WH-26 (59.09 t/ha), whereas, the commercial check NS-295 produced 32.34 t /ha. During 2008-2009, of the hybrids evaluated, the hybrid WH-35 gave the highest yield (112.67 t/ha), which differed significantly from rest of the hybrids evaluated. This was followed by the hybrids WH-24 ( 90.73 t/ha). The pooled analysis of data revealed that two hybrids, namely, WH-35 (79.18.68 t/ha) and WH-24 (7519.20 t/ha), out yielded the commercial check NS-295 (47.02.8t/ha). These F1 hybrids (WH-35 and WH-24) have been identified at Institute level by Institute Variety Identification Committee during 2009 for further testing in the growers’ fields. The hybrid WH-35 produces oblong shaped fruits. The rind colour is green with dark green ,broad broken stripes. The T.S.S is 13.05 per cent, the average fruit weight is 10.38 kg. The flesh is red , juicy and sweet . The hybrid WH-24 produces oval shaped fruits. The rind colour is dark green with light green, broken stripes. The flesh colour is red with a TSS of 11.55 per cent. The average fruit weight is 8.15 kg with 1-2 fruit per vine whereas, the commercial check hybrid NS-295, produces oblong shaped fruits. The rind colour is light green with green stripes. The flesh colour is red with a T.S.S. of 10.91 per cent.|
