from flower buds before anthesis and from open flower heads. is the male part of a flower and transferred to the flower’s female part called the stigma (1997) Cicer arietinum × C. reticulatum Ladizinsky and Adler (1976a, b) C. arietinum × C. echinospermum Pundir and Mengesha (1995) C. arietinum × C. pinnatifidum Mallikarjuna (1999) C. arietinum × C.bijugum Clarke et al. and Devel. A good gram crop in case of desi (black varieties) gives an output of 15 to 20 quintals yield per hectare and in case of Kabuli varieties gives about 25 to 30 quintals yield per hectare. A true-breeding black gram (Vigna mungo) × green gram (Vigna radiata) derivative was reciprocally crossed with adzuki bean, Vigna angularis. This method greatly shortens the juvenile phase of orchids and, under optimal conditions, enables us to induce flowering and evaluate the flower quality about 5-6 months after seed germination. In Biology and breeding of food legumes, QTL analysis of domestication syndrome in zombi pea (Vigna vexillata), an underutilized legume crop, QTL Analysis of Domestication Syndrome in Zombi Pea (Vigna vexillata), an Underutilized Legume Crop, ASSESSMENT OF GENETIC PURITY OF INTER-SPECIFIC F1 HYBRIDS INVOLVING VIGNA RADIATA AND VIGNA UMBELLATA, Breeding for Insect Resistance in Mung Bean and Urd Bean, Ultrastructural Studies on the Fusion Product between Protoplasts of Mung Bean and Adzuki Bean Iriawati, Interspecific hybridization between mung bean (Vigna radiata) and adzuki bean (V. angularis), On the Interspecific Hybrdization between the Adzuuki Bean, Phaseolus angularis (WILLD) W.F.WIGHT and the Green Gram, Phaseolus radiatus L. : I. Such situation is found in tomato and brinjal. velocity, insect pollinators and supplementary pollination. Its hybridity was confirmed at the seedling stage based on the presence of the green epicotyl colour of the adzuki bean. P.M. A.M.i cent- age of total in 3) Study of floral structure of self pollinated crops. It ensures self pollination and prevents cross pollination. of inspections to be conducted. Here pollination occurs before floer opening (cleistogamous) in night. Pollination is of two types: viz. The methods of embryo rescues facilitate the interspecific crosses and contribute to exploiting the available genetic diversity within plant germplasm. The rooted shoots were hardened and observed for morphological characters. 1) Autogamy or self pollination and 2) Allogamy or cross pollination. Am. The application of growth regulators to pistils for delaying the initiation of abscission of pods is usual for numerous interspecific hybridizations. Here, stigmas remain densely and closely surrounded by anthers. Forced self pollination did not set seeds in these hybrids, but seeds were obtained when pollinated with ICPL 85010. Furthermore, a successful interspecific hybrid of V. mungo x V. angularis was accomplished through the use of intraspecific hybrid parents. Comparison of domestication-related QTLs of the zombi pea with those of cowpea (Vigna unguiculata), azuki bean (Vigna angularis), mungbean (Vigna radiata) and rice bean (Vigna umbellata) revealed that there was conservation of some QTLs for seed size, pod size and leaf size between zombi pea and cowpea and that QTLs associated with seed size (weight, length, width and thickness) in each species were clustered on same linkage. Seed Propagated Rice, Wheat, Barley, Oats, Chickpea, Pea, Cowpea, Lentil, Green gram, Black gram, Soybean, Common bean, Moth and Devel. In vitro flowering and in vitro pollination: methods that will benefit the orchid industry. In Vigna species, early generation (F 1 and F 2 ) hybrid progenies derived from hybridization of distantly-related genotypes always possesses pods with incomplete filled (empty seeds in some locules) [49. 1991, Verma and Brar 1996. The purpose was to avoid self-incompatibility after in vitro self-pollination of ovules isolated 24 and 48 h after pollination.One fertile pod containing two hybrid seeds was obtained, when V. angularis was used as the male parent. No. Pollen germination percentage and number of flowers for each clone were also investigated. early dry period, could be to take full advantage of the first rainy season for vegetative growth and reproduction. Two domesticated forms of zombi pea are cultivated as crop plants; seed and tuber forms. The green grams are the most commonly grown in Kenya. In vitro mutation in flower colour was detected in one branch of the same plant with 10 Gy irradiation. endemic succulent of the Magaliesberg mountain range, previously thought to be largely sunbird (specialist) pollinated. Chickpea (gram) can be grown as one crop or combine with barely, linseed, mustard, peas, corn, coffee, safflower, potato, sweet potato, wheat or sorghum etc. Pulse crops (Red gram, Black gram and Green gram) are basically self-pollinated in nature and don’t need any external pollination practices. However, high incidence of insect pests in these crops is a major constraint in achieving their potential productivity and resulting in yield instability over the years. 1991 ) Chromosome doubling using colchicine Chaisan et al.
