RESUMEN
Crop related information is provided to the farmers by Government bodies and Private organisations.Farmers use this information to make farming profitable by selecting suitable varieties for that region.The information is not common to every farming station. Data mining techniques applied for provided crop research data customises it to each farming station. Present studies has been carried out on application of data mining in selection of suitable rice variety to Warangal region by obtaining the data of 20 years. Theeight rice varieties recommended by rice research station, focussing on six traits were considered for the present study. Results show that Ramappa, JGL 384, Swarna, Samba masuri are high yielding varieties in Warangal region. Kavya, MTU 1010 andWGL14 have high harvested grain weight whereas Sureka, Samba Masuri and Ramappa have least. Kavya and WGL14 showed high straw strength, panicle length and carbohydrate content. This analysis helps the farmer to select particular combination of traits to identify high performing varieties for specific location.
RESUMEN
Infection of the pebrine disease has been found to be highly virulent and harm the cocoon yield as well as characters of silkworm Anthereae mylitta. Therefore, an attempt was made to evaluate the impact of parasite Nosema species on the ecorace (Sukinda) of A.mylitta in respect of transovarial transmitted (T1), secondary infection (T2) and healthy silkworm (T3). In comparison to T3, the number of larval mortality was 16 and 11 in T1 and T2 respectively; whereas as number of pupal mortality was 6 and 5 in T1 and T2 respectively.The larval weight, number of moths emerged, number of eggs laid and percent hatchability were reduced in T1 and T2 in comparison to T3.The infected layings were high in T1(51%) and T2(42%) as against T3(0%). Similarly, the infected moths were 34% in T1 and 15% in T2 as against 0 percent in T3.All the characteristics parameters of cocoon were reduced in T1 and T2 against T3. The study explains that there was no significant variation between T1 and T2 on different parameters of larva, pupa and cocoon characters.
RESUMEN
Antheraea mylitta produces tasar silk and is an endemic species of the Indian subcontinent. Populations of this species show a certain degree of phenotypic variability for which they are designated as ‘ecoraces’. Inorder to study the genetic variability in relation to the environment among Daba T.V and Andhra local the life history of two ecorace from hatching to egg laying stage and the cocoon characters were enumerated. Andhra local ecorace has exhibited superior qualities in fecundity, shell ratio,silkyield,filament length,reelability and denier whereas mothemergence, larvalweight, cocoonweight,shell weightand effective rate of rearing have been encouraging in Daba T.V.Thus the variations in the above characters could be attributed to the genetic variability between the two ecoraces rather than the environment influence as they are reared under similar environment.
