“…The reasons for this situation are low quality fodder and limited feed availability. Because of low quality fodder and feed, animals reach puberty later, and the intercalving interval is shorter (Ali, 2011;Mumtaz et al, 2017b). This situation could be improved with increased milk and meat productivity per animal, and increased chicken production, and targets could be achieved by increasing milk, meat and chicken production up to 100% with good quality fodder and feed availability.…”

This study was conducted to compare the performance of ten sorghum hybrids at two locations (Maize and Millets Research Institute, Yusafwala, Sahiwal, MMRI) & Sorghum Research Sub-Station, Dera Gazi Khan, D.G. Khan) for two consecutive years (2015 and 2016), i.e. in a total of four environments (MMRI-15, MMRI-16, DG Khan-15 and DG Khan-16). The experiment was conducted in a Randomized Complete Block Design with a plot size of 4 × 0.75 × 2 m. In all four environments the crop was sown in July and harvested in December. Five plants were selected randomly from each plot for data collection. The following ranges were determined in the investigated traits; grain yield (2858.34-5266.33 kg ha-1), fodder yield (28663-45667 kg ha-1), days to 50% anthesis (76-81 days) and Brix value (8.28-18.42). Analysis of variance (ANOVA) estimates, generated by the biplot software were used for data interpretation. It was found that the influence of genotype, environment and G × E interaction was significant (P<0.05) for all traits in all environments. The data for all traits except Brix value were useful for further study. For grain yield and fodder yield, hybrid YSH-95 was the most suitable due to its higher yield and better stability. Sorghum Research Sub-Station Dera Gazi Khan (DG Khan), a non-discriminating location, were considered suitable for generally adapted hybrids and Maize and Millets Research Institute, Yusafwala, Sahiwal (MMRI), a more discriminating location, were considered best for specifically adapted hybrids. The results of which-won-where biplots showed that Lasani was the best general hybrid at both locations, whereas YSH-95 was the best hybrid for the specific environmental conditions at MMRI.

“…Currently, existing B. rapa varieties are have limitations such as a low yield, aphid attack, white rust of crucifer, low percentage of better quality oil, and shattering at maturity. Additionally, lodging problem due to winds and rains is also a major limitation (Mumtaz et al, 2014). Farmers are also reluctant to grow it due to problems in its economic return but with such varieties of high yielding and short duration, its area and production can be increases and farmers can be attracted towards it.…”

Pakistan is deficient in production of edible oil. 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.

The sunflower is a remarkable oilseed crop due to better oil composition and short duration. In this experiment combining ability was computed for achene yield and its related trait. Fifteen genotypes of sunflower were crossed by using line × tester pattern. Out of 15 genotypes, A6, A7, A10, A11, A12, A17, A19, A20, A21 and A26 were taken as females (lines) and A8, A9, A16, A18 and A22 were taken as male (testers). The parental and 50 F1 crosses seed was sown in randomized complete block design in 3 replications in next growing season. The data was recorded for leaves/plant, leaf area, plant height, head angle, fresh head diameter, dry head diameter, number of achenes/head, average yield/plant, 100 achene weight and harvest index. The recorded data was used to estimate the genetic of descriptive traits among the genetic material. Heterosis study revealed that A19 × A22 was best hybrid for plant height. A21 × A8 performed well for number of achenes per head and directly involved in increasing yield. A7 × A8 hybrid combinations expressed positive and significant SCA values for average yield. The intermediate inheritance pattern was observed for all traits. It can be concluded that investigated material can be efficiently used for the development of high-yielding hybrids along with genetic improvement of sunflower accessions for different traits.
