Performance evaluation and correlation analysis in mithipagal genotypes (Momordica charantia var. muricata)
Abstract
The evaluation of twenty genotypes of mithipagal was carried out under Periyakulam condition. Observation were recorded for the following traits viz, vine length, days to male flower appearance, days to female flower appearance, nodes of male flower appearance, nodes of female flower appearance, sex ratio, fruits per vine, fruit weight, fruit length, fruit girth, fruit thickness, seeds per fruit, yield per vine, ascorbic acid, momordicine content, protein content and total soluble solids. Among the genotypes, MC 7 (0.64 kg) followed by MC 20 (0.62 kg) and MC16 (0.53 kg) recorded the highest mean value of fruit yield. Correlation analysis revealed that fruit yield per vine was significant and positively correlated with vine length, nodes of female flower appearance, fruits per vine, fruit length, fruit girth, fruit weight, fruit thickness, seeds per fruit, momordicine content and protein content. However negative association was observed with days to first male flower appearance, days to first female flower appearance and nodes of first male flower appearance. Hence selecting mithipagal genotypes with high fruit weight, more number of fruits per vine and seeds per fruit, fruits with high flesh thickness and momordicine and protein content will help to improve yield per vine and quality of mithipagal fruits.
