| Summary, etc. | The evaluation of morphological characters and compatibility analysis of 14 selected genotypes was undertaken in the present study titled "Compatibility studies of three way crosses in Anthurium andreanum Linden. The analysis of variance revealed significant variation among the 14 genotypes for the 18 characters studied. This reveals genetic potential for crop improvement. Variability studies indicated high phenotypic, and genotypic coefficients of variation for the characters internode length, number of leaves and spadices per plant per year and days from emergence to maturity of leaves. The characters with high heritability coupled with high genetic advance values were leaf area, anthocyanin content and inclination of candle indicating additive gene action. Plant height was found to be positively correlated with number of leaves or spadices per plant per year. Candle length had positive genotypic correlation with position of candle. Pollen fertility ranged from 9.26 per cent in PR x DT to 35.70 per cent in Carre. Pollen emergence was completely absent in the genotype W x LJ during the course of the study. Pollen production was high in the r, cooler months of October to December and was suppressed in the months from March to June. From the cross compatibility analysis, it was seen that the percentage of fruit bearing candles was highest for W x LJ (100.00 %) with two crosses. The cross PR x LR with all the possible four crosses gave a value of 79.15 per cent. The number of fruits per candle ranged from 12 to 120. 00 x KR had the highest average number of fruits per candle and it was lowest for 00 x PR. The percentage of fruit set was below 50 per cent for all the crosses. The crosses involving 00 x KR had the highest average percentage of fruit set. The number of days taken for germination varied from four to nine days. The seed germination was highest (87.30 %) for the cross (00 x KR) x H. No cross showed 100 per cent survival beyond four to six months. For PR x LR with all the possible four crosses, the survival percentage was 56.80 per cent. Scoring of the compatibility reactions based on the percentage of fruiting candles, fruit set and seed germination on a scale ranging from zero to nine showed the highest compatibility score of nine for (00 x KR) x C. The best female parents identified were 00 x KR and PR x LR based on the overall performance. |
