INTERRELATIONSHIPS AMONG YIELD COMPONENTS AND PLANT GROWTH CHARACTERS, AND THEIR CONTRIBUTION TO YIELD IN TWO SPECIES OF MUSTARD

Twelve cultivars belonging to two species of Brassica were used to determine the nature and degree of interrelationships among yield components and some plant growth characters, and their contribution to yield. Nine characters were studied and simple, partial, and multiple correlation coefficients were computed. Results indicated that pod length, number of pods per plant, number of seeds per pod, and seed weight per pod were positively and linearly associated with seed yield per plant and that these four component characters of yield were also interrelated with plant height. The percentage of oil in the seeds was positively correlated with seed weight, but negatively with number of seeds per pod. Late maturity was found to be undesirable because it reduces number of pods per plant.
