41 Method of mass production of soil-less arbuscular mycorrhizal fungal inoculums

Method of mass production of soil-less arbuscular mycorrhizal fungal inoculums As per the Bureau of Indian Standards (BIS) specifications, an AM fungal inoculum should contain a minimum of 100 propagules per gram of substrate. Traditionally, the inoculum is multiplied on live host plant roots grown on different substrates like sand: soil mixture, vermiculite, perlite, etc which are bulky materials for handling and transport. Further, propagule count on such media does not meet the standards often.

42 Centella asiatica genotypes, IIHR CA-1 and IIHR CA-13

Centella asiatica genotypes, IIHR CA-1 and IIHR CA-13 genotypes were identified In India, to date there is only one variety Vallabh Medha developed at DMAPR. Considering its importance, the work was initiated on this crop at IIHR and, 16 germplasm lines have been collected and maintained. The systematic assessment of this collection for biomass yield and quality has lead to identification of two genotypes namely, IIHR CA-1 and IIHR CA-13. Method of breeding for the development of these varieties is Single plant clonal selection.

43 Onion varieties and F1 hybrids suitable for development of Paste

Developed onion varieties and F1 hybrids suitable for Paste India is the second largest producer of onion in the world accounting for 16 % area and 10 % of production. In our country, onion is grown in 0.5 million hectare with production of 5.5 million tones. The major onion growing states are Maharashtra, Madhya Pradesh, Gujarat, Karnataka, Bihar, Telangana and Andhra Pradesh. Nearly 40 % of onion produced does not reach the consumers because of various types of losses due to PLW, handling and storage loss, etc.

44 ICAR-IIHR Developed 3 new Rose Varieties Arka Ivory, Arka Pride and Arka Sukanya

ICAR-IIHR Developed three new Rose Varieties Arka Ivory, Arka Pride and Arka Sukanya ICAR-IIHR developed the following new Rose varieties: 1) Arka Ivory - It is rose variety Ideal for cut flower production under protected cultivation. Potential yield of 110 fls/sq.mit. It is moderately resistant to mites. 2) Arka Pride - It is a cut flower rose variety suitable for protected cultivation Potential yield of 120fls/sq.mt and 3) Arka Sukanya - It’s a fragrant rose variety with 0.22% of concrete yield in fresh flowers.

45 Dipping of fruits in mango wash

Dipping of fruits in mango wash Mango blackening caused by sooty blotch and flyspeck (SBFS) complex is a kind of cosmetic skin problem and causes only superficial damage on the mango fruit surface. The fungi that cause them, grow on the surface of the cuticle and do not damage the fruit itself. But cause losses in commercial mango production because affected fruits are rejected in fresh market grades to much cheaper rate which causes financial loss to the mango growers and traders. As such there is no technology available in India to remove this malady of mango.

46 ICAR-IIHR developed two Ridge Gourd Varieties

ICAR-IIHR Developed two Ridge Gourd Varieties Arka Prasan: This open pollinated ridge gourd variety has been identified for release by the Institute VTIC during 2016. Early flowering and first female flower appears at 9th node from the base of the vine. Takes 34-35 days for the first female flower appearance and 42-45 days for first picking of fruits. Produces green, long, tender fruits. Excellent cooking quality, nutritionally rich in antioxidant activity and minerals like phosphorus, Calcium and zinc. Yields 26.0 t/ha in 120-135 days duration.

47 Biological control of Mango inflorescence hoppers Idioscopus spp

Biological control of Mango inflorescence hoppers Idioscopus spp Mango is an important subtropical fruit in India, with high commercial value in internal and export markets. Among the insect pests mango inflorescence hoppers Idioscopus spp at flowering is the most serious.Infestation of the hoppers cause withering of flowers, sooty mold formation due to honey dew secretion resulting up to 100 percent loss in fruit setting and thereby on yield. Presently insecticidal control is recommended for the management of mango hoppers.
