Domestic edible oil production needs to be increase. Brassica rapa can be a better source for filling the gap between consumption and production of oil production, due to its yellow seeded nature. The goal of this study is to gather and develop information on genetics of different plants and seed yield related traits of Brassica rapa. A randomized complete block design is used for estimation of the genetic expression on seed yield related traits using four lines (UAF-11, Toria, BSA and TP-124-1) in diallel fashion. Statistical analysis was analyzed using Statistix 8.1. The presence of partial dominance type of gene action and the absence of epistasis was observed. Partial dominant gene action was observed in all traits. Direction of dominance was more frequent towards better parents except seed yield per plant. The number of recessive genes were more than that of dominant genes except number of seeds/siliqua. Maternal effects were observed in all traits. This study shows that UAF-11 is the best parent for Brassica rapa because it has the maximum dominant genes for almost all traits and can be utilized in future breeding efforts.

Thanks to its short life cycle, high yield and yellow seed colour, oilseed rape (Brassica rapa L.) is a potentially useful source to fill the gap between production and consumption. This study was designed to ascertain the genetic expression of descriptive and seed yield-related traits in four B. rapa accessions (UAF-11, Toria, BSA and TP-124-1) and their hybrid progenies obtained from complete diallel mating crossings. Heterosis and heterobeltiosis were computed for these traits. Seed colour was varying shades of brown and showed Mendelian genetics. Seed shape was consistently round in all lines, and leaf hairiness was a characteristic of all crosses including self. Each parent line had a particular leaf shape as elliptic, pandurate, lanceolate and ovate, and no intermediate or new shapes were observed in F 1. Leaf colour was varying shades of green. Seed shape, leaf shape and leaf colour were under digenic control with no epistatic or maternal effects. Leaf shape showed multiple allelism. Seed shape showed no variations. Leaf hairiness was dominant and under monogenic control. Number of siliqua/primary branches of plant, number of siliqua/secondary branches of plant and total number of siliqua/plant directly affect seed yield of plant while effect of plant height is indirect. Variability was observed in heterosis and heterobeltiosis for all traits. UAF-11 and its crosses with Toria and TP-124-1 and their reciprocals were identified as the best hybrid progenies for future breeding efforts. Our results for the traits, compared here will, hopefully, facilitate future efforts to select productive B. rapa accessions for breeding programs aimed at optimizing heterosis.

Sorghum is a good alternative to meet the growing fodder and poultry feed requirements. The major barrier in enhancing sorghum production is the lack of sufficient information on the genetic diversity of sorghum genotypes in Pakistan. In this study 30 sorghum genotypes from the gene pool maintained by the Maize and Millet Research Institute, Yusafwala, Sahiwal, Pakistan were sown in 2015 in a randomised complete block design. Morphological data such as days to 50 % anthesis, plant height, flag leaf area, brix percentage, panicle length, 1000 grain weight and grain yield were recorded. Data were evaluated for statistical significance using principal component analysis (PCA) and cluster analysis. A highly significant variation was observed among the genotypes. The percentage coefficient of variation in all traits was less than 10 %, which showed that uncontrolled variation was highly unlikely. A close correlation was seen between flag leaf area and grain yield, days to 50 % anthesis and 1000 grain weight, and between panicle length and brix value. Flag leaf area, grain yield and 1000 grain weight indicated the least contribution to the total genetic diversity. The contribution of PC1, PC2 and PC3 was 64.5 % of total variation. According to PCA and cluster analysis genotype YS-9 was important for the character days to 50 % anthesis; genotype YS-22 for grain yield and flag leaf area; genotype YS-27 for plant height; genotype YS-10 and genotype YS-7 for panicle length; and genotype YS-12 for brix value.

It was found that the genotypes OH8, K55TMS and A495-2 performed better under normal and drought stress conditions. Higher heritability and genetic advance was recorded for shoot length, root weight and biomass of seedling. It was concluded that significant correlation was found for root length with shoot length, fresh biomass, dry root length and dry shoot weight. Significant correlation of root length and shoot length indicated the genotypes with higher root and shoot length showed drought stress resistance. It was suggested that selection on the basis of root and shoot length may be helpful to improve maize yield under drought stress conditions.
