The motivation behind the investigation was to distinguish the harvest assortments in the Haor territory of Netrokona locale to limit the nourishment weakness circumstance during nourishment emergency. The examination was directed in four chose towns of Madan and Khaliajuri Upazilas under the Netrokona region. Information were gathered from haphazardly chosen 400 ranchers from the examination zone in the year 2011. The discoveries of the investigation uncovered that ranchers ordinarily develop just three HYV boro rice assortments (BR 19, BRRI dhan 28 and BRRI dhan 29) in the Haor region under examination. In aman season ranchers generally develop neighborhood assortments and they get least yield. Just barely any vegetables found to develop by the ranchers in Haor territory. The vegetables are: onion, garlic, stew, bottle gourd, sweet gourd, woman's finger and tomato. Among these onion, garlic and bean stew are for the most part developed. Numerous ranchers detailed that during the flood they needed to confront difficult issues in regard of correspondence, illnesses, expanded cost of various wares, and absence of satisfactory government security net projects/help. Ranchers' absence of flood readiness has been watched while a few ranchers remained uncared about the event of flood and thusly they didn't take any readiness for flood.

Rice is a brief day plant and flowering is promoted in quick day situations and suppressed in long day condition. the short-day condition allows the manufacturing of flowers in distinct flowering ranges which substantially helps synchronous flowering for sorts that fluctuate of their flowering time. The heading date for synchronization of Paw San Hmwe (PSM) and other four indica rice sorts were studied below short-day period and neutral day length circumstance and F1 seed set become observed from hybridization of PSM and indica rice varieties by using hot water emasculation method. results confirmed days to a heading of PSM and different four indica sorts in short day period have been earlier than those in impartial day duration. some of the examined types, PSM changed into rather touchy to high temperature and photoperiod in impartial day length because of no longer most effective flowering in short-day photoperiod circumstance however additionally photoperiod sensitive and past due cultivar. the existing examine revealed that although five rice varieties have been cultivated to modify synchronization underneath impartial day length and brief day length for hybridization, synchronization for PSM and different 4 indica rice types become now not located in both conditions as it might be distinctive genetic version on the tested varieties and sowing date of examined types changed into same underneath neutral day length and short day period circumstance. Synchronization changed into determined in short day period and cultivation in a concrete tank of internet residence. PSM from quick day duration circumstance become used as a female determine for hybridization because it was synchronized with the alternative three indica sorts from 2nd-time cultivation within the concrete tank of internet residence. The F1 seed set percent of PSM x IR 24 became higher than the other tested crosses and collected two F1 hybrids (PSM x IR 24 and PSM x Thaichung 65). therefore, brief day period condition (9-hour light and 15 hours darkish) may be used for synchronization and hybridization on rice genotypes mainly PSM (photoperiod sensitive range) compared to impartial day length situation. The F1 hybrids (PSM x IR 24 and PSM x Thaichung 65) from this study need to be used to get new rice varieties through several techniques.
