Abstract

Chilli (Capsicum annum) is the predominant sp., which is cultivated in both hot and sweet papers. The maintenance of the genetic purity of chilli plant is a matter of great concern for the breeders. For genetic purity analysis, between true hybrids and off-types, breeders find out morphological differences between them, but this technique is cannot be recognized easily and also costly, tedious to score, and environmentally sensitive. Alternatively,  molecular markers based genetic purity analysis can be employed. The molecular marker-based technique was thus used to overcome the conventional method drawbacks. The main objective of the study is to identify informative molecular markers (ISSR and RAPD) capable of distinguishing Chilli hybrids and their parental lines and their utilization in seed purity assessment. Five parental lines of Chilli (i.eCH10, CH12, CH530, CH709, CH734) were used for the production of 3 hybrids. Total 30 ISSR and 8 RAPD primers were selected for the study of 5 parental lines, among them 2ISSR and 1 RAPD primers produced unique fingerprinting across the hybrids. The ISSR marker UBC815 amplified alleles specific to different parental lines(CH10 & CH12) for hybrids (ACH112), The ISSR marker UBC 827, amplified alleles specific to different parental lines(CH709 & CH12) for hybrids (ACH179). Likewise, RAPD primer B20 for hybrid ACH 753 and their parental lines(CH734 & CH530). Thus, the above study showed that the aid of molecular markers is more reliable, highly efficient, and reproducible for assessing fingerprinting of Chilli commercial hybrid seeds with more accuracy.
