Two Cytoplasmic Male Sterile lines were crossed with fourteen restorer lines of rice widely grown in the western regions of Maharashtra, India, to produce 28 F1 hybrids which were evaluated for eight agronomically important traits, contributing to yield potential, in replicated field trials. The hybrid performance was recorded along with heterosis and heterobeltiosis. All the rice lines under investigation were subjected to marker-based variability analysis. An attempt was made to correlate genetic distance based on specific markers for each trait individually, as well as average genetic distance based on all specific markers, with hybrid performance and heterosis, by regression analysis. Specific markers could cluster the parental lines in different groups and showed significant correlation with hybrid performance. The data also supports the proposition that epistasis is the basis of heterosis. The analysis, however, revealed a lack of significant predictive values for field application.

Objective:Indian papaya or Carica papaya is known to have de-sloughing and wound-healing properties due to the presence of protease enzymes. The present study was done to compare the efficacy and safety of papaya dressing with hydrogen peroxide solution for preparation of wound bed in patients of postoperative wound gape.Materials and Methods:A randomized, open-labeled interventional study was carried out over a period of 8 months at a tertiary care hospital on post-caesarean section patients with wound gape. The efficacy parameters studied were duration of time required to induce development of healthy granulation tissue and total duration of hospitalization. Safety parameters studied were adverse effects reported by patients and development of hypersensitivity reaction.Results:A total of 64 patients were enrolled, of which 32 patients received hydrogen peroxide dressing and 31 patients received papaya dressing (one patient withdrew after randomization). Time required to induce the development of healthy granulation tissue and total duration of hospitalization were 6.2 ± 1.6 days vs 2.5 ± 0.5 days and 19.2 ± 5.8 days vs 12.92 ± 4.6 days in papaya and hydrogen peroxide dressing groups, respectively. Both primary efficacy parameters were significantly shorter in papaya dressing group. The incidence of adverse effects like local irritation and itching were comparable in both groups and the difference was not statistically significant.Conclusion:Papaya dressing is more efficacious and equally safe as compared to hydrogen peroxide dressing when used for wound bed preparation in patients with postoperative wound gape.
