The studies indicated that sympodial branches had strong positive correlation with plant height, monopodial branches and number of bolls per plant while it negatively correlated with number of seeds per lock, number of seeds per boll and boll weight. Plant height had strong positive association with bolls per plant. The number of locks per boll had positive correlation with boll weight and number of seeds per boll while it negatively correlated with tapering boll shape. Number of seeds per boll correlated positively with boll weight and lint percentage. Number of seeds per lock had strong positive association with number of seeds per boll and boll weight. Number of seeds per boll correlated positively with boll weight. Lint percentage had no association with any of the traits studied. Fibre length correlated positively with fibre strength while these traits had no correlation with any plant morphological trait.

A field research was conducted under field situation at the Research Area, University of Agriculture, Faisalabad, to study the combining ability effects for yield and its components in sunflower. Fifteen accessions of sunflower were crossed in line x tester fashion. Crosses along with their parents were grown in the field. For this purpose 10 lines (G-16, G-68, G-146, G-55, G-82, G-40, G-9, HBR-5, A-18 and G-57) and 5 testers (G-3, G-32, G-61, G-50, and G-54) were crossed according to line x tester fashion. Among the lines G-82, G-40, G-9 and HBR-5 showed positive and significant GCA effects for No. of achene per head, 100 achene weight, and achene yield per plant and proved to be good general combiners for most of these characters. Among the testers G-3, G-61 and G-54 proved as good general combiners for most of the characters i.e. for number of days to flowering, plant height, internodal length, No. of achene per head and achene yield/ plant. The hybrids G-146 x G-54, G-16 x G-61, and G-82 x G-3 showed good specific combining effects are for all the characters. Genotypic differences were significant for all the characters."

Investigations were done to find out the Agro-qualitative response of forage maize (Zea mays L.), blended and intercropped with forage legumes.The experiment consisted of 10 treatments containing different combinations of maize with legumes i.e. sesbania and cluster bean.This study was focused to achieve high quantity and better quality of maize fodder.Aim of the study was to determine the more efficient method of sowing and to have a look on the most favorable combination of maize and legumes. The better sowing method and combination of legumes with non-legume fodder can provide the higher quantity and better quality of fodder to the dairy industry of Pakistan.Data on growth, yield and quality parameters was recorded by using standard procedures, statistically analyzed using Fishers analysis of variance technique and least significant difference (LSD) test at 5 % probability will be used to compare the treatment's means.Keeping in view the results of the present study, it was concluded that the good quantity and quality of forage maize (Zea mays L.) sown mixed with forage legumes can be obtained by interrow growing of maize and sesbania in 30 cm apart rows under Sahiwal conditions

Complete diallel mating design of five parents NIAB KRISHMA, SLS-1, MNH-513, BH-162 and LA.FREGOBRACTS-3159 were used in the crosses to study the inheritance pattern and combining ability for various plant traits such as plant height, number of monopodial branches, number of sympodial branches, number of bolls per plant, seed cotton yield, boll weight, GOT, fiber length, fiber strength and fiber fineness in cotton (Gossypium hirsutum L.). The data collected were subjected to analysis of variance technique which shows significant results of all characters. The characters showing significant genotypic differences were further analyzed genetically following the diallel analysis which show that the regression co-efficient for all traits deviates significantly from zero but not from unity which reveals that data of all traits is free from epistasis. Varieties MNH-513 and NIAB Krishma show better results according to yield components and fiber characters due to having more dominant genes and better combining ability comparatively other varieties.
