The experiment was carried out at Research Farm in Department of Agronomy, Punjab Agricultural University, Ludhiana to work out effective weed management strategy in transplanted rice. Nine treatments viz. pendimethalin + pyrazosulfuronat 675 + 15 g, 900 + 20 g, 1125 + 25 g, pendimethalin at 1500 g, pyrazosulfuronat 15 g, pyrazosulfuronat 20 g, metsulfuron + chlorimuronat 4 g ha -1 , hand weeding and weedy check replicated thrice laid out in randomized complete block design (RCBD). The results revealed that pendimethalin + pyrazosulfuron at 1125 + 25 g ha -1 , provided effective weed control (73.8-86.2% weed control efficiency) over other treatments. During 2015, pendimethalin + pyrazosulfuron at 1125 + 25 g ha -1 was found profitable with higher rice grain yield (6.65 t ha -1 ) and cost benefit ratio (1:2.25). Pendimethalin + pyrazosulfuronatat 900 + 20 g ha -1 , was found profitable with higher rice grain yield (7.35 t ha -1 ) and cost benefit ratio (1:2.50) and was statistically at par with pendimethalin + pyrazosulfuron at 1125 + 25 g ha -1 for weed control during 2016.
本试验在旁遮普省农业大学农学系研究农场进行，旨在制定插秧水稻有效的杂草管理策略。采用随机完全区组设计(RCBD)进行了手除草和杂草试验，9个处理分别为:二甲甲烷+吡唑磺隆675 + 15g、900 + 20g、1125 + 25g、二甲甲烷1500 g、吡唑磺隆15g、吡唑磺隆20g、甲磺隆+氯脲4g ha -1。结果表明，喷施1125 + 25 g ha -1的二甲甲烷+吡唑隆对杂草的防效为73.8% ~ 86.2%。2015年，使用1125 + 25 g - ha -1的二甲甲烷+吡唑隆可获得较高的水稻产量(6.65 t - ha -1)和成本效益比(1:2.25)。在2016年的杂草防治中，使用900 + 20 g - ha -1的二甲醚+吡唑磺隆具有较高的水稻产量(7.35 t - ha -1)和成本效益比(1:2.50)，在统计上与使用1125 + 25 g - ha -1的二甲醚+吡唑磺隆相当。

The genetic gain for yield in wheat and other cereals has been known to be stagnating in recent years. Breeding wheat cultivars with increased genetic potential can contribute to meet at least half of the desired production increases. In this context we have developed some advanced wheat lines in our breeding program, which aims to utilize the untapped variability. We assessed a set of 60 diverse lines along with four commercial check varieties for various agro-morphological traits, grain quality and yield based and also the adaptability using molecular markers. Significant genotypic differences were observed for most of the grain quality and agro-morphological traits recorded, including grain yield. We could identify lines which have significantly higher grain yield. The diversity analysis carried out using the DNA markers could explain the variability for different traits in this set. This set of genotypes is thus a very useful source as far as enhancing the yield levels. The lines developed through the conventional breeding program were based on crosses between elite breeding lines and specific donors and hence might resulted in higher yield potential.

Barley (Hordeum vulgare L.) is included in the family of grasses and is the fourth highly significant crop after maize, wheat and rice. Barley is considered as an important food ingredient because of the presence of vital biochemical constituents viz. β-glucan, starch, amylose, protein etc. Barley is usually classified as hulless or hulled types (absence or presence of hull adhering to grain). Hulless barley needs negligible processing and preserves maximum of the endosperm and germ, which is once in a while lost during the time spent for dehulling. As a result, it is highly suitable for human utilization, as the entire grain can be specifically utilized to form a meal or processed into flour. Interest in the use of hulless barley as a food grain has expanded primarily due to its stated health benefits .The regular intake of hulless barley contributes to maintenance of normal blood cholesterol level, beneficial in preventing certain types of cancer like colon cancer and also provides better glucose and insulin responses. Hulless barley has high β-glucan content which helps in lowering of glycemic index and also causes the stimulation of bowel health. For this reason food industry is anxious about expanding the utilization of these cereals as nourishment fixings and henceforth more research is merited here.

Development of hybrids in wheat is an innovative approach for enhancing present productivity levels. Presence of standard or commercial heterosis is essential for successful development of a hybrid cultivar. The discovery of heterosis and its exploitation in modern plant breeding programmes is one of the most important advances in plant improvement (Alghamdi, 2009). Although hybrid development in wheat could not achieve any success in the world but efforts are being made for development of CMS (Cytoplasmic Male Sterility) based hybrids in wheat for marginal land with half seed rate and in this direction, more than 50 diversified cytoplasmic male sterile (CMS) lines were developed in agronomic background of Indian wheat cultivars using backcross breeding at ICAR-IIWBR, Karnal (Singh et al., 2016). These new CMS lines were evaluated for male sterility and 12 CMS lines in agronomic background of DBW 17 (a promising cultivar of NWPZ were crossed with 3 fertility restorer lines (Res 5, Res 37 & Res 38) during 2016-17 crop season to develop 36 experimental hybrids.

An experiment was conducted for two consecutive years (2012-13 and 2013-14) to determine the effect of different inducer chemicals on spot blotch disease of wheat and its impact on grain yield. All the inducer chemicals reduced the spot blotch infection significantly at different concentration levelsand also increase the yield attributing characters like number of grains/panicle and 1000 seed weight. The accumulation of phenol increased up to 96 days after sowing (DAS), whereas, peroxidase accumulation increased up to 68 days after sowing in wheat plants in all the treatments.Among the different inducer chemicals salicyclic acid (10 -4 M) and CuSO4 (10 -4 M and 10 -5 M) showed good results even at low concentration levels. Therefore, the inducer chemicals can be used as an alternative method to manage the spot blotch of wheat.
