Ideotype and relationship between morpho-physiological characters and yield in Indian mustard (Brassica juncea)

Abstract

Twelve genotypes of Indian mustard [Brassica juncea (L.) Czemj. & Cosson] were evaluated for various yield and morpho- physiological characters during 1990 and 1991. The genotypes were classified basal or non-basal branching type on the basis of the presence or absence of at least 1 productive primary branch within 30 cm height of the plant. A correlation analysis revealed that the traits related to basal branching were positively associated among themselves as well as with the seed yield. There were desirable and negative associations of basal branching characters with flowering time and plant height. Thus breeding for early maturing basal branching plant types with medium height and high yield is possible.
