DEPARTMENT OF GENETICS AND PLANT BREEDING JUNAGADH AGRICULTURAL UNIVERSITY JUNAGADH - 362 001, GUJARAT, INDIA * EMAIL: mayurdarwankar@gmail.com _____________________________________________________________________ ABSTRACT Thirty diverse genotypes of coriander were grown in three different environments (D 1 to D 3 ) created by sowing dates during rabi 2011-12 at Vegetable Research Station, Junagadh. Seed yield per plant was positively and significantly correlated with harvest index and 100-seed weight at both genotypic and phenotypic level in all the three dates of sowing, whereas, seed yield per plant had significant and positive correlation with umbellets per plant in D 2 at both genotypic and phenotypic level and in D 1 at phenotypic and in D 3 at genotypic level. In addition to that, in timely sowing condition (D 2 ), seed yield per plant showed significant and positive correlation with longest basal leaf length and number of basal leaves at genotypic level and with number of fruit bearing branches at phenotypic level. In late sowing condition (D 3 ), seed yield per plant showed significant and positive correlation with number of fruit bearing branches and umbels per plant at genotypic level. This indicated that importance of these traits as compliment of seed yield. Path coefficient analysis revealed that the days to 50 per cent flowering, 100- seed weight, plant height, number of basal leaves, longest basal leaf length, umbels per plant and umbellets per plant in early sown condition (D 1 ); harvest index, days to 50 per cent flowering, longest basal leaf length, umbels per plant, umbellets per plant, seeds per umbel and 100-seed weight in timely sown condition (D 2 ); and days to 50 per cent flowering, plant height, number of basal leaves, number of fruit bearing branches and umbellets per plant in late sown condition (D 3 ) exhibited high and positive direct effects on seed yield per plant. KEY WORDS: Coriander, correlation, path analysis, environme INTRODUCTION Coriander (Coriandrum sativum L.) is an important seed spice crop belonging to the family Apiaceae (previously classified under the family Umbelliferae) with a diploid chromosome number 2n=22. Improvement in seed yield could be achieved through selection of component characters influencing yield. An understanding of the character association of component traits with yield and their direct effects in path analysis is important for effective selection of traits for high yield. But the estimates of correlation coefficients and path coefficients are subjected to change by the
