High yielding and moderately resistant to fruit rot disease chilli hybrid – CCH 1 (TNAU Chilli Hybrid CO 1)

Anthracnose is one of the serious diseases in chilli which affects whole plant and also fruits in particular. A study was undertaken to develop a high yielding and anthracnose disease resistant hybrid in chilli at the Dept. of Vegetable Crops, HC & RI, TNAU, Coimbatore during 2004-05. As a first step, ninety three germplasm lines maintained in the Dept. of Vegetable crops were evaluated for disease resistant and yield. Three single plant selections namely Sln 1, Sln 2 and Sln 3 made in advanced generations of a hybrid were found to be resistant and the genotypes Arka Lohit, Pepper Hot, CA 97, KDC 1, CC 4, CA 95, CA 115 and CA 59 were found to be moderately resistant. These selected lines were used both as male (testers) and lines as female parents and 30 hybrids were obtained. All these hybrids were tested for the performance of yield, quality and disease resistance. Among them the hybrid combination of Sln 1 x CA 97 was identified as best performed hybrid CCH 1(TNAU Chilli Hybrid CO 1). This was test verified across the state in 8 MLT and 103 ART plots along with NS 1701 and K 1 as check. The results showed that the per cent increase was 14.65 over NS 1701 and 51.40 over K 1for green fruit yield and 19.15 and 60.86 for dry fruit yield respectively. The fruit rot incidence in terms of Percentage of Disease Index (PDI) observed was 12.50 and hence it is comes under moderately resistant group. This entry CCH 1 has been released as TNAU Chilli Hybrid CO 1 during the year 2009-10.
