“…Similarly, V 1 (116 days), V 10 and V 12 (115 days each) also took lesser number of days to reach maturity compared with check varieties. Similar findings have been observed by ( Siyal et al, 2020 ) who confirmed that days to reach maturity play a role in wheat yield.…”

“…Likewise, V 11 , V 19 , V 22 and V 23 followed V 10 and V 20 and took comparatively lesser number of days to spike emergence than the rest of the lines ( Table 3 ). An earlier study found that wheat variety taking less number of days for heading is categorized early maturing ( Siyal et al, 2020 , Takumi et al, 2020 , Tiwari et al, 2019 ).…”

“…Most of the tested lines exhibited medium stature like V 6 , V 12 except V 11 (70.4), V 12 (80.6 cm), V 13 (75.4 cm), V 15 (72.5 cm), V 17 (69.1 cm), V 18 (72.5 cm), V 19 (76.4 cm), V 20 (69.4) and V 21 (71.4), whereas minimum value for plant height was observed for V 29 (59.9 cm). ( Siyal et al, 2020 , Zhao et al, 2018 ) reported that medium statured genotypes had higher grain yield than tall statured genotypes.…”

Global wheat yields are suffering due to differences in regional climatic conditions and soil fertility. Plant breeders are continuously working to improve the yield per unit area of wheat crop through selecting superior lines as parents. The screening and field evaluation of available lines allow the selection of superior ones and subsequently improved varieties. Therefore, heritable distinctions among 33 bread wheat lines for yield and related attributes were assessed under field conditions. The experiment included thirty lines and three check varieties. Data relating to different plant characteristics was collected at maturity. Significant differences were recorded for yield and related traits of tested wheat lines and check varieties. Wheat lines V 6 , V 12 and V 20 proved better with reduced number of days to reach anthesis and other desirable traits compared to check varieties. Days to start heading had strong correlation with spike length and number of spikelets spike -1 . Flag leaf area had positive relationship with peduncle length and yield related traits. The 1000-garin weight and grain yield were also correlated with each other. It is concluded that V 6 , V 10 and V 20 proved better for all studied traits than the rest of the lines. Therefore, these lines could be used in wheat breeding program as parents to improve yield.

“…Hence, in case of branching capacity, the Pr-75 and Pr-102 could be considered as the most promising lines for using in future breeding programs on linseed. Found the visible effects of Environmental effect on branches number [11]. Capsules plant -1 Capsules contain the seeds in flowering plants like linseed, and it is generally said that more the capsules in a plant, greater the yield plant -1 .…”

Variability and genetic diversity assessment is foremost activity to be embarked before any crop improvement programme. Divergence analysis is helpful in identifying suitable and diverse parents for realizing high heterotic effects with transgressive sergeants in later generations. Thus, a research study was design to study and the purpose of this study remained to evaluate the variation in seed germination, days taken to flowering and maturity, height of the plant, branches and capsules per plant, thousand grains weight, oil content percentage and seed yield kg per hector at Oilseeds Section, Agriculture Research Institute, Tandojam Pakistan. Six linseed varieties (including candidates and one commercial variety), viz., Pr-83, 84, 102, 17, 75 respectively and Ilsi-90 as check were evaluated for their growth, seed yield and oil yield performance. The field experiment was set up in Randomized Complete Block Design with three replications.The achieved results pointed out that except seed germination, all the growth and seed yield related traits as well as oil content differed significantly (P<0.05) in diverse linseed varieties. It was concluded that linseed candidate varieties Pr-75 and Pr-17 surpassed commercial linseed variety Ilsi-90 (check) in all the growth and seed yield works as well as in oil content, which is a most significant consequence of this experiment, and the varieties Pr-75 and Pr-17 could be promising for general cultivation in Sindh province.

“…Ngwako and Mashiqa (2013) also reported the same results for this character. According to a previous study, wheat varieties that take fewer days to mature are classified as early maturing (Siyal et al, 2020;Takumi et al, 2020). Morpho Yield Attributes of Bread Wheat…”

W heat is a winter cereal crop which requires relatively low temperatures ranging from 12 to 22º C and these temperatures are considered optimum for its reproductive development (Farooq et al., 2011). This crop is considered amongst the most important crops in Pakistan because of its contribution of 1.6% and 8.9% in GDP and value added in agriculture of our homeland being cultivated on 8.74 million hectares up to 2019 yielding 25.195 million tonnes (GOP, 2019). For our country, this Abstract | A fast change in the climate has perplexed the world by creating drought and its related issues. In this way, plenty of hexaploid wheat is influenced in our Pakistan. For combating this situation, research was carried out on sixteen bread wheat genotypes to see the effect of water stress at the experimental field, NIA, Tandojam in an RCBD with factorial arrangement of three treatments i.e. T 1 (zero irrigation), T 2 (two irrigations), T 3 (four irrigations) during Rabi season, 2016-2017. The ANOVA results exposed significant differences among genotypes as well as treatments for most of the attributes, however genotypes x treatment was also significant for several characters. Among the treatments, T 3 (four irrigation) recorded higher mean perform then T 2 (two irrigation) and T 1 (zero irrigation) which showed that different irrigation regimes caused significantly impact on all the traits. Among the genotypes, V3-10-34 showed minimum reduction in spike length, spikelets per spike, grains per spike, seed index, grain yield per plant and harvest index. The genotype, V2-10-15 manifested minimum decrease for days to 75% maturity and spikelets per spike at zero irrigation and two irrigations. C7-98-4 gave minimum decrease for flag leaf area and V2-10-3 caused smaller amount of reduction for biological yield plant -1 at zero irrigation and two irrigations. The genotypes like V3-10-34, V2-10-15, C7-98-4 and V2-10-3 could be recommended for the water deficiency areas of farmers.
