Traits association and path value analysis of Gymnema sylvestre cuttings for higher survival percentage under the influence of PGRs

Abstract

Twenty genotypes of radish (Raphanus sativus L.) were evaluated in Randomized Block Design during Rabi season 2010-11 at experimental farm of Horticultural Research Centre, Chauras Canpus, H.N.B. Garhwal University, Srinagar (Garhwal), Uttarakhand (India) to assess the correlation coefficient and path coefficient analysis. Root yield/plant was positively correlated with plant height 40 days after sowing, number of leaves 40 days after sowing, plant height 50 days after sowing, number of leaves 50 days after sowing, plant height 60 days after sowing, number of leaves 60 days after sowing, number of leaves 70 days after sowing, total plant height after harvesting, total plant weight and leaf weight, while it showed negative correlation with plant height 70 days after sowing at phenotypic and genotypic levels. The maximum positive direct effects on root yield/plant was observed by number of leaves 70 days after sowing followed by plant height 70 days after sowing and plant height 60 days after sowing, while plant height 50 days after sowing, number of leaves 60 days after sowing, total plant height after harvesting, total plant weight and root length had negative direct effect.
