“…2). Considerably lower temperature during the early growth stages resulted in the prolonged vegetative phase in case of early transplanting date (Abhilash et al 2017). Crop geometries also reacted differently for number of days required to attain distinct phenological stages (Fig.…”

Field experiment was conducted during 2021 at Division of Agronomy, SKUAST-K, Wadura with three dates of transplanting Kharifviz viz . 05 June, 15 June and 25 June and three crop geometries ., 15 cm x 10 cm, 15 cm x 15 cm and 20 cm x 15 cm. The study used th th th microclimatic modifications by adjusting the sowing time and crop geometry. The early transplanted treatment (5 June) did better than those th transplanted in latter weeks of June in terms of growth, phenology, grain yield and low blast disease incidence of scented rice-. MushkBudji Variations among crop geometries were also observed, with crop spacing 20 cm x 15 cm required more time to attain different phenological stages thus producing a higher yield at harvest and low blast disease incidence of rice-. Moreover, statistically significant MushkBudji interactions between the were identified, where early transplanted rice crop (5 June) at transplanting dates and crop geometries on grain yield th spacing 20 cm x 15 cm (T S ) proved to be the better combination for maximum yield. The study concluded that early transplanting (5 June) 1 3 th with spacing 20 cm x 15 cm (S ) realized higher growth, yield parameters and low blast disease incidence of rice-under lower 3 MushkBudji altitude belts (1590 amsl) of Kashmir.

Cold stress affects growth and development of rice plants from germination to reproductive stages. Thirty breeding lines/varieties including tolerant and susceptible check varieties were evaluated for cold tolerance at seedling and reproductive stage using artificially induced low temperature situations to understand the genetic relationship among them and to identify promising donors for cold tolerance. Three breeding lines, BR8253-9-3-4-3, IR77497-31-2-3-1and IR2266-42-6-2 demonstrated higher cold tolerance for the seedling stage (LD score <3.0). Molecular analysis revealed 68% genetic similarity among the genotypes. On average 64% of the breeding lines shared common alleles at any given locus ranging from 27% (RM22870) to 97% (RM186). UPGMA dendrogram showed that majority of the breeding lines showing 4-5 degrees of LD were grouped together. Two breeding lines, BR8258-7-1-5-2B2 and BR8258-7-1-5-2B3 having 86% common alleles showed low leaf discoloration (LD: 4) at seedling stage coupled with relatively low reduction in spikelet fertility (45.8% and 48.1%) and grain yield (43.3% and 39.1%). The gene diversity and PIC value revealed that seven SSR loci (RM1282, RM600, RM5349, RM6972, RM5847, RM5911, and RM511) might be the best markers to differentiate between tolerant and susceptible genotypes at reproductive stage. The breeding lines with tolerance to cold stress at the seedling and the reproductive stages identified from this study, and the SSR markers mentioned above could be useful for developing cold tolerance rice.
