  In mustard (Brassica juncea) broad-sense heritabilities, coefficients of variability and genetics advance values were computed for primary branches, plant height, siliquas per plant and seed yield per plant in four single crosses. Number of siliquas per plant were highly heritable coupled with high genetic advance and coefficient of variability. It reflected a great scope for selection. Cross combinations 86-4-3 x Poorbi Raya and 86-16-1 x Poorbi Raya were particularly valuable for various characters. They gave high heritability and genetics advance for most characters. Indicating that selection should lead to a fast genetic improvement of the material.

  Five cross of Brassica juncea viz., SMP 13-78 x Zem-I, SML 31E x Zem-I, DL 8 x Zem-I, SM 83000 x Zem-I, Pr 171-71 x Zem-I were made. These crosses (F1's) along with their parents were sown and heterosis was studied for branches per plant, plant height (cm), number of siliquas and yield per plant (g) in F1 generation. It was found that a cross of SMP 13-78 x Zem-I showed maximum heterosis and heterobeltotic for all the characters studied. Therefore, this cross combination can fruitfully be utilized for improving yield and its components in future breeding programmes.

  The extent of amenable genetic variability and association of important agronomic characters were determined in a set of 21 genotypes of sesame under Faisalabad conditions. The extent of genetic coefficient of variability, heritability and genetic advance as percent of mean in that order were 18.47,95.68,37.23; 89.04, 97.02, 1.33; 26.00, 94.49, 55.23; 12.81, 94.15, 25.61; 16.10, 99.02, 32.93 and 32.45, 99.97, 66.67 percent for plant height, number of branches per plant, number of capsules per plant, number of seed per capsule, 1000-seed weight and seed yield per plant, respectively. The number of capsules per plant contributed the highest towards seed yield followed by 1000-seed weight and plant height. Selection emphasis on these traits could result in improvement of seed yield.
